QUIZ 1. Which word does not describe the process of cellular respiration reactions? a. Redox reactions b. Exothermic reactions c. Catabolic reactions d. Anabolic reactions Answer: d. These reactions are all exothermic (giving off heat), catabolic (breakdown), redox reactions (involving the exchange of electrons and hydrogen ions). They are not anabolic. 2. Which aspect of aerobic biochemical reactions leads to the most ATP molecules? a. Fermentation b. Glycolysis c. Electron transport d. Krebs cycle Answer: c. Electron transport yields many more ATP molecules (about 34 theoretically) when compared to the other aspects of aerobic respiration. 3. Where in the cell does glycolysis take place? a. Nucleus b. Rough endoplasmic reticulum c. Cytoplasm d. Mitochondria Answer: c. Glycolysis specifically happens in the cytoplasm without the aid of any membranes. It delivers the pyruvate molecules to the mitochondria for the rest of the pathway leading to aerobic respiration.
