MB CH7- Microbial Metabolism PT1 Quiz

What is the relationship among metabolism, catabolism, and anabolism?

• Metabolism is the process of breaking down larger molecules into smaller ones, while catabolism is the synthesis of cell molecules and structures.

• Metabolism is the process of breaking down larger molecules into smaller ones, while anabolism is the synthesis of cell molecules and structures.

• Metabolism is the process of synthesizing larger molecules from smaller ones, while catabolism is the breakdown of cell molecules and structures.

• Metabolism is the process of synthesizing larger molecules from smaller ones, while anabolism is the breakdown of cell molecules and structures.

What is the significance of the electron transport system?

• It transfers energy stored in acetyl CoA to NAD and FAD

• It transfers electrons from reduced carriers to generate ATP

• It converts glucose to pyruvic acid and releases energy

• It breaks down larger molecules into smaller ones and releases energy

How does anaerobic respiration differ from aerobic respiration?

• Anaerobic respiration uses oxygen as the final electron acceptor, while aerobic respiration uses other oxidized inorganic compounds

• Anaerobic respiration uses other oxidized inorganic compounds as the final electron acceptor, while aerobic respiration uses oxygen

• Anaerobic respiration does not require oxygen, while aerobic respiration does

• Anaerobic respiration produces more ATP than aerobic respiration

How are noncarbohydrate compounds catabolized?

• They are converted into glucose through glycolysis

• They are broken down into smaller molecules through the Krebs cycle

• They are used as terminal electron acceptors in the electron transport chain

• They are converted into ATP through fermentation

What is the final destination for electrons being transferred through the electron transport chain?

• NADH dehydrogenase

• Flavoproteins

• Coenzyme Q (ubiquinone)

• Cytochromes
