Cellular Respiration and Fermentation Exam Questions with Correct Answers
100% Verified| Guaranteed Success
Aerobic Respiration Metabolic process in which pyruvate is broken down and electron-
carrier molecules are used to produce ATP through electron transport chain.
Cellular Respiration Catabolic pathway for the production of ATP, by breaking down glucose
and other food molecules in which oxygen is consumed as a reactant.
Redox Reaction A chemical reaction involving the transfer of one or more electrons from
one reactant to another; also called oxidation-reduction reaction.
What is Oxidation and Reduction LEO the lion says GER (Lose Electrons:Oxidation. Gain
Electrons:Reduction) The reducing agent loses electrons and thus is oxidized in reaction.
The oxidizing agent gains electrons and thus is reduced in the action.
NAD+/NADH An organic molecule that serves as an electron carrier by being oxidized (losing
electrons) to NAD+ and reduced (gaining electrons) to NADH
Electron Transport Chain A sequence of enzymes that act as electron carrier molecules that
transfer electrons and release energy during cellular respiration to produce ATP from ADP.
Electron Transport The movement of electrons from one electron carrier to another in a
series of oxidation-reduction reactions, with each electron transferred to a slightly lower level
of energy, so that energy is released. Electron transport is used in the light reactions of
photosynthesis and in the final stage of cellular respiration to produce ATP from ADP and
phosphate.
Glycolysis A metabolic process that breaks down carbohydrates and sugars through a series
of reactions to either pyruvic acid or lactic acid and release energy for the body in the form of
ATP. (Glyco=Sugar; Lysis=Breaking)
