| Question | Answer |
|---|---|
| The term for when enzyme activity is controlled by binding of a compound to a site other than the active site is called: | allosteric regulation. |
| The citric acid cycle in eukaryotic cells takes place in the: | mitochondrial matrix. |
| Metabolic pathways are: | a series of linked chemical reactions that result in a final end product. |
| When a glucose molecule loses a hydrogen atom/electrons as a result of an oxidation-reduction reaction, the molecule becomes: | oxidized |
| Which of the following BEST describes the products of the full metabolic pathway of glycolysis? | 2 ATP, 2 NADH and 2 pyruvates |
| The immediate energy source that drives ATP synthesis by ATP synthase during oxidative phosphorylation is the: | the flow of H+ down their concentration gradient. |
| Which of the following statements correctly describes the relationship between NADH and NAD+? | NAD+ is reduced to NADH during glycolysis. |
| Phosphofructokinase (enzyme) in glycolysis, which is part of how cells process sugar for energy. It converts a mole. into fructose 1,6-bisphosphate early in this pathway. When ATP levels are high, ATP turns off phosphofructokinase. This is an example of: | negative feedback inhibition |
| The primary role of oxygen in cellular respiration is to: | act as an acceptor for electrons and hydrogen, forming water. |
| Which part of cellular respiration is directly responsible for the most ATP production? | chemiosmosis |
