Categorize the following: Aerobic respiration, Anaerobic respiration, Fermentation, None of these .Assume in all cases that these processes follow breakdown of glucose by glycolysis. Results in complete oxidation of glucose to CO2 Involves regeneration of reduced co-factors (e.g. regenerating NAD+ from NADH) Generates energy by substrate level phosphorylation only Generates ATP by oxidative phosphorylation Utilizes an electron transport chain Uses molecules such as NO3 - , SO4 2- , or Fe3+ as terminal electron acceptors Products include organic acids, alcohols,...

Q1: What are catabolism and anabolism (4 marks)? Q2: Under aerobic respiration, a molecule glucose is oxidized to generate 36 ATPs in eukaryote cell while 38 ATPs in prokaryote cell. Explain how this difference occurred (6 marks). Q3: Why aerobic respiration could produce more energy (ATP molecules) than anaerobic respiration and fermentation? By using glucose as the substrate, illustrate how ATP molecules are being produced in each case (15 marks). Q4: "Most microbes use carbohydrate (glucose) as the energy sources...
