6 Multiple choice questions
- An enzyme that catalyzes a chemical reaction during which one or more hydrogen atoms are removed from a molecule
- 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
- a quantity of heat equal to 1,000 calories. Used to measure the energy content of food, it is usually called a "Calorie"
- The metabolic cycle fueled by acetyl CoA formed after glycolysis in cellular respiration. Chemical reactions in the citric acid cycle complete the metabolic breakdown of glucose molecules to carbon dioxide. The cycle occurs in the matrix of mitochondria and supplies most of the NADH molecules that carry energy to the electron transport chains. The second major stage of cellular respiration.
- The conversion of pyruvate from glycolysis to carbon dioxide and ethyl alcohol
- The production of ATP using energy derived from the redox reactions of an electron transport chain; the third major stage of cellular respiration
6 True/False questions
oxidation → The loss of electrons from a substance involved in a redox reaction; always accompanies reduction
acetyl CoA → The gain of electrons by a substance involved in a redox reaction; always accompanies oxidation
facultative anaerobe → An organism that makes ATP by aerobic respiration if oxygen is present, but that switches to fermentation when oxygen is absent
glycolysis → The multistep chemical breakdown of a molecule of glucose into two molecules of pyruvate; the first stage of cellular respiration in all organisms; occurs in the cytoplasmic fluid
reduction → The loss of electrons from a substance involved in a redox reaction; always accompanies reduction
lactic acid fermentation → The conversion of pyruvate from glycolysis to carbon dioxide and ethyl alcohol
