6 Multiple choice questions

  1. a quantity of heat equal to 1,000 calories. Used to measure the energy content of food, it is usually called a "Calorie"
  2. The entry compound for the citric acid cycle in cellular respiration; formed from a fragment of pyruvate attached to a coenzyme
  3. The formation of ATP by an enzyme directly transferring a phosphate group to ADP from an organic molecule
  4. 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
  5. An organism that makes ATP by aerobic respiration if oxygen is present, but that switches to fermentation when oxygen is absent
  6. 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

6 True/False questions

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

          

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

          

  3. redox reactionShort for oxidation-reduction; a chemical reaction in which electrons are lost from one substance (oxidation) and added to another (reduction). Oxidation and reduction always occur together

          

  4. dehydrogenaseAn enzyme that catalyzes a chemical reaction during which one or more hydrogen atoms are removed from a molecule

          

  5. obligate anaerobesAn organism that makes ATP by aerobic respiration if oxygen is present, but that switches to fermentation when oxygen is absent

          

  6. glycolysisThe 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
