1. B. Why do macromolecules differ in the amount of energy they contain? The amount of energy stored in macromolecules varies because their chemical structures and therefore the energy contained in their chemical bonds differ.

What is the effect of charge differences that build up across the inner mitochondrial membrane during cellular respiration?

What is the effect of charge differences that build up across the inner mitochondrial membrane during cellular respiration? H+ ions continue to build causing the membrane to burst and sending an influx of H+ ions across the membrane.

How is the chemical energy contained in glucose similar to money in a savings account?

Just like the money in a savings account the glucose is stored in the body in the form of ATP. Whenever the body needs energy the ATP is taken and consumed. Using the ATP is like withdrawing the money from the bank account and spending the cash.

What is the main reason organisms need food?

Organisms need to take food to get energy and perform life processes. A living organism undergoes many life processes like nutrition respiration digestion transportation excretion blood circulation and reproduction. To perform all these life processes the organism needs energy and nutrients.

Why do all organisms need matter and energy?

All living organisms need energy to grow and reproduce maintain their structures and respond to their environments. Metabolism is the set of life-sustaining chemical processes that enables organisms transform the chemical energy stored in molecules into energy that can be used for cellular processes.

Which is necessary for a plant to convert the energy of the sun into energy it can use?

Plants must take in carbon dioxide and water. They use energy from the sun to convert carbon dioxide and water into glucose and oxygen.

How does the location of ATP synthase differ between prokaryotes and eukaryotes Where do protons accumulate as a result of the ETS in each cell type?

How does the location of ATP synthase differ between prokaryotes and eukaryotes? … In prokaryotic cells protons flow from the outside of the cytoplasmic membrane into the cytoplasm. In eukaryotic cells protons flow from the inner mitochondrial membrane space to the mitochondrial matrix.

How are alcoholic fermentation and lactic acid fermentation similar How are they different?

The similarity is that they both happen under anaerobic conditions and produce a little amount of ATP. The difference is that alcoholic fermentation gives CO2 while lactic acid does not.

What happens to the concentration of H+ in the intermembrane space and the matrix as electrons move down the ETC?

What happens to the concentration of H+ in the intermembrane space and the matrix as electrons move down the ETC? The concentration of the intermembrane increases while the concentration of the matrix decreases. Where does the H+ come from that makes ATP synthase work? … To create hydrogen ions.

How does photosynthesis and cellular respiration have opposite effects on gases in the atmosphere?

Photosynthesis takes in CO2 and releases O2. Cellular respiration takes in O2 and releases CO2. “Photosynthesis and cellular respiration have opposite effects on gases in the atmosphere.” Explain this statement. … Its used to make carbon dioxide NADH ATP and FADH2.

Is glucose a chemical energy?

A molecule of glucose which has the chemical formula C6H12O6 carries a packet of chemical energy just the right size for transport and uptake by cells. In your body glucose is the “deliverable” form of energy carried in your blood through capillaries to each of your 100 trillion cells.

How is the function of NAD+ similar to that of NADP+?

The function of NAD+ is similar to that of NADP+ because they both are electron carries that accept high energy electrons and are converted and used in electron transport chains. … Cellular respiration (including the Krebs cycle and the electron transport chain) requires oxygen.

How does food turn into energy?

Through the process of cellular respiration the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration glucose and oxygen are converted into carbon dioxide and water and the energy is transferred to ATP.

Which macromolecule provides the energy that starts glycolysis?

Glycolysis begins with glucose and produces two pyruvate molecules four new ATP molecules and two molecules of NADH.

How energy released during respiration is stored?

Releasing energy in the form of ATP

Respiration releases energy – it is an exothermic process. The energy is stored in molecules of ATP . ATP can be broken down in other processes in cells to release the stored energy.

Why are the majority of organisms so similar in their energy metabolism?

Answer: organisms and the complexity of metabolism researchers have found that all branches of life share some of the same metabolic pathways suggesting that all organisms evolved from the same ancient common ancestor. ATP is the major carrier of biologically utilizable energy in all forms of living matter.

How do different organisms obtain and use energy to survive in their environment?

1: Most energy comes from the sun either directly or indirectly: Most life forms on earth get their energy from the sun. Plants use photosynthesis to capture sunlight and herbivores eat those plants to obtain energy. Carnivores eat the herbivores and decomposers digest plant and animal matter.

Why isn’t all the energy transferred to the next organism where does it go?

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. … A food chain can usually sustain no more than six energy transfers before all the energy is used up.

How do plants turn sunlight into energy in scientific terms?

Plants convert sunlight into usable energy through the process of photosynthesis. Light energy from the photons strikes the chlorophyll in the leaves which causes a chemical reaction between the chlorophyll carbon dioxide and water creating C6H12O6 or sugar.

How do plants absorb light energy from the sun?

Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun’s energy and turns it into chemical energy. … With the chlorophyll gone the green light is not being reflected anymore!

What are plants that convert energy from the sun called?

They make it themselves! Plants are called autotrophs because they can use energy from light to synthesize or make their own food source.

Why do eukaryotes produce less ATP than prokaryotes?

In eukaryotic cells unlike prokaryotes NADH generated in the cytoplasm during glycolysis must be transported across the mitochondrial membrane before it can transfer electrons to the electron transport chain and this requires energy. As a result between 1 and 2 ATP are generated from these NADH.

Why do prokaryotic and eukaryotic cells have different type of producing energy?

The hallmark feature that distinguishes eukaryotes from prokaryotes is that eukaryotic cells contain compartments called organelles that are surrounded by membranes. Each organelle supports different activities in the cell. … Prokaryotes lack mitochondria and instead produce their ATP on their cell surface membrane.

How does cellular respiration differ in prokaryotes and eukaryotes?

Both eukaryotic and prokaryotic organisms get the energy they need to grow and maintain normal cellular function through cellular respiration. … In eukaryotes most cellular respiration reactions take place within the mitochondria. In prokaryotes they occur in the cytoplasm and/or within the cell membrane.

Which is a major difference between lactic acid fermentation and alcohol fermentation?

The main difference between lactic acid and alcoholic fermentation is that lactic acid fermentation produces lactic acid molecules from pyruvate whereas alcoholic fermentation produces ethyl alcohol and carbon dioxide. Alcoholic fermentation of yeast is used in the food industry to produce wine and beer.

How do lactic acid and alcoholic fermentation differ quizlet?

Lactic Acid happens in the muscles while Alcoholic happens in the production of alcohol and bread. The product of lactic acid fermentation is lactic acid but the products of alcoholic fermentation is ethanol and Co2. The main difference between aerobic and anaerobic is the presence of O2.

How are lactic acid fermentation and alcoholic fermentation different quizlet?

They are different in that alcoholic fermentation produces alcohol and carbon dioxide while lactic acid fermentation produces lactic acid. When the race is over the only way to get rid of lactic acid is through a chemical pathway that requires extra oxygen.

What is the effect of H+ accumulation in the intermembrane space?

What is the effect of proton accumulation in the intermembrane space? The accumulation of protons decreases pH in the intermembrane space and creates a proton gradient.

What is the function of the protein channel where H+ ions escape into the matrix of the mitochondrion?

The inner membranes of the mitochondria contain protein spheres called ATP synthases. As H+ ions escape through channels into these proteins the ATP synthase spins. As it rotates the enzyme grabs a low-energy ADP attaching a phosphate forming high-energy ATP.

What happens to the concentration of hydrogen in the intermembrane space?

The pumping of hydrogen ions across the inner membrane creates a greater concentration of the ions in the intermembrane space than in the matrix. This chemiosmotic gradient causes the ions to flow back across the membrane into the matrix where their concentration is lower.

How the molecules in photosynthesis and cellular respiration are similar?

The two processes are similar in that they both produce energy albeit in two different forms. … The win-win of the two processes is that they both provide each other with the necessary ingredients for the process to take place: glucose and oxygen for cellular respiration carbon dioxide and water for photosynthesis.

What made the two processes different from each other of cellular respiration and photosynthesis?

The main difference between photosynthesis and cellular respiration is that photosynthesis is an anabolic process where the synthesis of organic compounds occurs storing energy whereas cellular respiration is a catabolic process where the stored organic compounds are utilized producing energy.

How are cellular respiration and photosynthesis related in terms of energy?
