Microbial Metabolism Quiz

Which of the following processes generates the most ATP during microbial metabolism?

• Glycolysis

• Krebs cycle

• Electron Transport Chain

• Fermentation

In the process of glycolysis, glucose is broken down into two molecules of:

• Carbon dioxide

• Pyruvate

• Lactate

• Acetyl-CoA

Which of the following serves as the terminal electron acceptor in aerobic respiration?

• Nitrate

• Oxygen

• Sulfate

• Carbon dioxide

Which of the following is an anaerobic process?

• Oxidative phosphorylation
