In what organelle would you find acetyl CoA formation, the citric acid cycle, and the electron transport chain? A. chloroplast B. nucleus C. mitochondrion D. Golgi apparatus E. lysosome

mitochondrion All of the steps of cellular respiration except glycolysis take place in the mitochondrion.

Which statement describes the citric acid cycle? A. This process produces some ATP and carbon dioxide in the mitochondrion. B. This process joins 2 pyruvic acid molecules into a molecule of glucose. C. This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration. D. This process converts pyruvic acid to acetyl CoA. E. This process splits glucose in half and produces 2 ATPs for each glucose

This process produces some ATP and carbon dioxide in the mitochondrion. The citric acid cycle breaks down carbon molecules, releasing carbon dioxide and forming some ATP.

which of the following is a common feature of the processes indicated (electrons carried by NADH and electrons carried by NADH and FADH2) A. movement of pyruvic acid into the mitochondria B. movement of hydrogen atoms associated with NADH C. movement of organic food molecules between catabolic pathways D. movement of phosphate groups associated with ADP

movement of hydrogen atoms associated with NADH The hydrogen atoms removed from food molecules during glycolysis and the Krebs cycle can be thought of as the combination of protons and high energy electrons. These are both carried by the coenzyme NADH (and FADH2) from the catabolic pathways to the electron transport chain.

Which of the following is following is a true statement regarding the reactions in substrate-level phosphorylation A. Together, the reactions indicated by the letters F and G produce most of the ATP synthesized during cellular respiration. B. Both reactions F and G include the synthesis of ATP powered by the diffusion of H+ ions. C. Both reactions F and G involve the transfer of a phosphate group from an organic substrate to ADP. D. Both reactions F and G involve the transfer of electrons from an organic substrate to the molecule ATP.

Both reactions F and G involve the transfer of a phosphate group from an organic substrate to ADP. they both indicate the synthesis of ATP by substrate-level phosphorylation

What is the correct general equation for cellular respiration? A. 6 O2 + 6 H2O + ATP energy → C6H12O6 + 6 CO2 B. C6H12O6 + 6 H2O → 6 CO2 + 6 O2 + ATP energy C. C6H12O6 + 6 CO2 → 6 O2 + 6 H2O + ATP energy D. C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + ATP energy E. 6 CO2 + 6 H2O + ATP energy → C6H12O6 + 6 O2

C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + ATP energy Cellular respiration extracts energy from glucose (C6H12O6) to produce smaller energy packets (ATP).

Which of the following processes takes place in the cytosol of a eukaryotic cell? A. glycolysis B. ATP production by ATP synthase C. electron transport chain D. citric acid cycle D. acetyl CoA formation

Glycolysis the breakdown of glucose into two molecules of pyruvic acid, takes place in the cytosol, outside the mitochondria.

Which statement describes glycolysis? A. This process produces some ATP and carbon dioxide in the mitochondrion. B. This process splits glucose in half and produces 2 ATPs for each glucose. C. This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration. D. This process joins 2 pyruvic acid molecules into a molecule of glucose. E. This process converts pyruvic acid to acetyl CoA.

This process splits glucose in half and produces 2 ATPs for each glucose. In glycolysis, glucose is split into two molecules of pyruvic acid. The released energy is stored in ATP and the electron carrier NADH.

Which statement describes the electron transport chain? A. This process converts pyruvic acid to acetyl CoA. B. This process joins 2 pyruvic acid molecules into a molecule of glucose. C. This process produces some ATP and carbon dioxide in the mitochondrion. D. This process splits glucose in half and produces 2 ATPs for each glucose. E. This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration.

This process uses energy captured from electrons flowing to oxygen to produce most of the ATPs in cellular respiration. In the electron transport chain, electrons move from one electron carrier to another, eventually reaching oxygen. The released energy is used to make ATPs.

Select the correct sequence of steps as energy is extracted from glucose during cellular respiration. A. citric acid cycle → electron transport chain → glycolysis → acetyl CoA B. electron transport chain → citric acid cycle → glycolysis → acetyl CoA C. glycolysis → citric acid cycle → acetyl CoA → electron transport chain D. acetyl CoA → citric acid cycle → electron transport chain → glycolysis E. glycolysis → acetyl CoA → citric acid cycle → electron transport chain

glycolysis → acetyl CoA → citric acid cycle → electron transport chain Glycolysis produces pyruvic acid, which enters the mitochondrion. There, it is converted to acetyl CoA, which enters the citric acid cycle. Electron carriers bring electrons from the first three steps to the electron transport chain, and ATP is made.

The term metabolism is best defined as ________. A. the length of time it takes to digest and absorb fats B. the number of calories it takes to keep from shivering on a cold day C. a measure of carbohydrate utilization, typically involving measurement of calories D. the sum of biochemical reactions involved in building and breaking down molecules
