6 Multiple Choice Questions

  1. 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
  2. a quantity of heat equal to 1,000 calories. Used to measure the energy content of food, it is usually called a "Calorie"
  3. The conversion of pyruvate from glycolysis to carbon dioxide and ethyl alcohol
  4. An organism that makes ATP by aerobic respiration if oxygen is present, but that switches to fermentation when oxygen is absent
  5. The conversion of pyruvate to lactate with no release of carbon dioxide.
  6. The formation of ATP by an enzyme directly transferring a phosphate group to ADP from an organic molecule

6 True/False Questions

  1. intermediatesThe gain of electrons by a substance involved in a redox reaction; always accompanies oxidation

          

  2. reductionThe loss of electrons from a substance involved in a redox reaction; always accompanies reduction

          

  3. chemiosmosisEnergy-coupling mechanics that uses the energy of hydrogen ion gradients across membranes to phosphorylate ADP; powers most ATP synthesis in cells

          

  4. glycolysisa quantity of heat equal to 1,000 calories. Used to measure the energy content of food, it is usually called a "Calorie"

          

  5. dehydrogenaseThe 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
