c. water
d. 6 nadh and 2 fadh₂

  1. what step of cell respiration takes place in the inner mitochondrial membrane?

a. krebs cycle
b. glycolysis
c. electron transport chain

  1. the electron transport chain and chemiosmosis do not require oxygen.

a. true
b. false

  1. which step of cellular respiration produces the most atp?

a. glycolysis
b. krebs cycle
c. electron transport chain

  1. which of the following is not produced by the electron transport chain?

a. atp
b. carbon dioxide
c. water

  1. about how many atp molecules are produced from one glucose molecule during respiration?

a. 30-38
b. 26-34
c. 6-12

Explanation:

Brief Explanations
  • Question 8: The Krebs cycle is also known as the citric acid cycle. The electron transport chain is a separate part of cellular respiration, and the Calvin cycle is in photosynthesis.
  • Question 9: The Krebs cycle produces carbon dioxide, ATP (2 per glucose molecule), NADH, and FADH₂. Water is produced in the electron transport chain.
  • Question 10: The electron transport chain occurs in the inner mitochondrial membrane. Glycolysis is in the cytoplasm, and the Krebs cycle is in the mitochondrial matrix.
  • Question 11: The electron transport chain and chemiosmosis require oxygen as the final electron acceptor.
  • Question 12: The electron transport chain produces the most ATP through oxidative phosphorylation.
  • Question 13: The electron transport chain produces ATP (through chemiosmosis) and water (from oxygen accepting electrons). Carbon dioxide is produced in the Krebs cycle.
  • Question 14: Approximately 30 - 38 ATP molecules are produced from one glucose molecule during aerobic respiration (this can vary slightly depending on the cell type and shuttle mechanisms for NADH).

Answer:

  1. B. citric acid cycle
  2. C. water
  3. C. electron transport chain
  4. B. false
  5. C. electron transport chain
  6. B. carbon dioxide
  7. A. 30 - 38
