Unit 3 AOS 1: DP 6

What role do proteins play in an organism's proteome?

• They provide structural support only.

• They act solely as transport molecules.

• They serve as catalysts in biochemical pathways and are a diverse group of molecules.

• They are involved only in the storage of genetic information.

What is the role of enzymes in biochemical pathways according to the learning goal?

• Enzymes reduce the structural diversity of proteins.

• Enzymes act as catalysts in biochemical pathways.

• Enzymes decrease the size of the proteome.

• Enzymes have no role in biochemical pathways.
