- a The electron acceptor in a redox reaction; oxidizes the reducing agent.
- b The loss of electrons from a substance in a redox reaction.
- c The H+ gradient that results from H+ being taken up and released into the surrounding solution of the intermembrane space at certain steps along the ETC.
- d A mode of ATP synthesis powered by the redox reactions of the ETC, an inorganic phosphate is added to ADP.
- e Requiring oxygen (referring to organisms, environments, or cellular processes).
5 Multiple Choice Questions
- An organism that makes ATP by aerobic respiration if oxygen is present but switches to fermentation under anaerobic conditions.
- A type of fermentation in which pyruvate is converted to ethanol by first releasing CO2, which is reduced by NADH to ethanol, NAD+ is produced for use in glycolysis.
- Catabolic process that involves a partial degradation of sugars, occurs without the use of oxygen.
- A mode of ATP synthesis that forms a smaller amount of ATP directly in a few reactions of glycolysis and the Kreb's cycle, occurs when an enzyme transfers a phosphate group froma substrate molecule to ADP.
- A sequence of electron carrier molecules (membrane proteins) that shuttle electrons during the redox reactions that release energy used to make ATP.
5 True/False Questions
Acetyl CoA → Requiring oxygen (referring to organisms, environments, or cellular processes).
Reduction → The addition of electrons to a substance in a redox reaction.
Anaerobic → Requiring oxygen (referring to organisms, environments, or cellular processes).
Glycolysis → The process in which energy stored in the form of an H+ gradient across a membrane is used to drive cellular work such as ATP synthesis.
Citric Acid Cycle → A metabolic sequence that breaks fatty acids down to two-carbon fragments that enter the citric acid cycle as acetyl CoA.
