6 Written questions

6 Multiple choice questions

  1. 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
  2. The gain of electrons by a substance involved in a redox reaction; always accompanies oxidation
  3. The loss of electrons from a substance involved in a redox reaction; always accompanies reduction
  4. The production of ATP using energy derived from the redox reactions of an electron transport chain; the third major stage of cellular respiration
  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. chemiosmosisThe 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


  2. ATP synthaseA 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. acetyl CoAThe entry compound for the citric acid cycle in cellular respiration; formed from a fragment of pyruvate attached to a coenzyme


  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. cellular respirationShort 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


  6. substrate-level phosphorylationThe formation of ATP by an enzyme directly transferring a phosphate group to ADP from an organic molecule
