6 Multiple choice questions
- An organism that only carries out fermentation; such organisms cannot use oxygen and also may be poisoned by it.
- The aerobic harvesting of energy from food molecules; the breakdown of food molecules, such as glucose, and the storage of potential energy in a form that cells can use to perform work; involves glycolysis, the citric acid cycle, and oxidative phosphorylation
- The loss of electrons from a substance involved in a redox reaction; always accompanies reduction
- The formation of ATP by an enzyme directly transferring a phosphate group to ADP from an organic molecule
- a quantity of heat equal to 1,000 calories. Used to measure the energy content of food, it is usually called a "Calorie"
- A cluster of several membrane proteins that function in chemiosmosis with adjacent electron transport chains, using the energy of a hydrogen ion concentration gradient to make ATP
6 True/False questions
oxidative phosphorylation → The formation of ATP by an enzyme directly transferring a phosphate group to ADP from an organic molecule
facultative anaerobe → An organism that makes ATP by aerobic respiration if oxygen is present, but that switches to fermentation when oxygen is absent
dehydrogenase → An enzyme that catalyzes a chemical reaction during which one or more hydrogen atoms are removed from a molecule
intermediates → One of the compounds that form between the initial reactant and the final product in a metabolic pathway, such as between glucose and pyruvate in glycolysis
redox reaction → The gain of electrons by a substance involved in a redox reaction; always accompanies oxidation
lactic acid fermentation → The conversion of pyruvate from glycolysis to carbon dioxide and ethyl alcohol
