Questions and Answers

What is the main difference between catabolism and anabolism?

Catabolism involves the TCA cycle, while anabolism involves hydrolysis reactions.
Catabolism involves breaking down complex molecules, while anabolism involves building complex molecules. (correct)
Catabolism requires energy, while anabolism releases energy.
Catabolism is a divergent process, while anabolism is a convergent process.

Which statement accurately describes catabolism?

Catabolism is a divergent process transforming common end products into various complex molecules.
Catabolism involves the degradation of energy-rich fuel molecules to capture chemical energy in the form of ATP. (correct)
Catabolism is known for the synthesis of complex end products from simple precursors.
Catabolic reactions are oxidative in nature using NAPDH as an electron donor.

What is the role of the tricarboxylic acid (TCA) cycle in metabolism?

To convert building blocks into acetyl CoA with no production of ATP.
To synthesize complex end products from simple precursors.
To convert ADP and Pi into ATP for energy storage.
To oxidize acetyl CoA and produce large amounts of ATP through oxidative phosphorylation. (correct)
