The breakdown of glucose during cellular respiration

D
The synthesis of proteins from amino acids
Verified step by step guidance

Understand the concept of catabolism: Catabolism is the set of metabolic pathways that break down molecules into smaller units and release energy. It is the opposite of anabolism, which involves the synthesis of complex molecules from simpler ones.
Identify the processes listed in the problem: The breakdown of glucose during cellular respiration, the formation of lipids from fatty acids, the conversion of glucose to glycogen, and the synthesis of proteins from amino acids.
Analyze each process: Determine whether each process involves breaking down molecules (catabolism) or building up molecules (anabolism).
Evaluate the breakdown of glucose during cellular respiration: This process involves breaking down glucose into carbon dioxide and water, releasing energy in the form of ATP. This is a catabolic process.
Compare with other options: The formation of lipids, conversion of glucose to glycogen, and synthesis of proteins are all anabolic processes, as they involve building larger molecules from smaller ones.
