6 Written questions

6 Multiple choice questions

  1. Short 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
  2. 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
  3. 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.
  4. The entry compound for the citric acid cycle in cellular respiration; formed from a fragment of pyruvate attached to a coenzyme
  5. An enzyme that catalyzes a chemical reaction during which one or more hydrogen atoms are removed from a molecule
  6. The conversion of pyruvate from glycolysis to carbon dioxide and ethyl alcohol

6 True/False questions

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

          

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

          

  3. facultative anaerobeAn organism that makes ATP by aerobic respiration if oxygen is present, but that switches to fermentation when oxygen is absent

          

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

          

  5. oxidationThe loss of electrons from a substance involved in a redox reaction; always accompanies reduction

          

  6. oxidative phosphorylationThe production of ATP using energy derived from the redox reactions of an electron transport chain; the third major stage of cellular respiration
