please answer question asap
Streptomyces griseus preferentially uses O2 as an electron donor, reducing it to H20. However, under conditions of limited O2, the strain can also use nitrate (NO) as an electron donor, reducing to to nitrite (NO27 Looking at the Electron transport chain components and reduction potentials below, would TO1 or TO2 be more energetically favorable in an ETC with nitrate as the terminal electron acceptor? How do you know? 3 pts) Ox/red CO2/glucose NO,-/NO, 0,/H,0 0.43 +0.43...

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...
