Verified step by step guidance

Understand the role of insulin in the body: Insulin is a peptide hormone produced by the pancreas that plays a crucial role in regulating blood glucose levels.

Identify the function of a growth factor: Growth factors are proteins that stimulate cell growth, proliferation, healing, and cellular differentiation.

Recognize that insulin, besides its primary role in glucose metabolism, also has growth-promoting effects on cells, which aligns with the function of a growth factor.

Differentiate between the options: Secondary messengers are molecules that relay signals received at receptors on the cell surface, adapter proteins are involved in signal transduction pathways, and effector enzymes are enzymes that bring about a cellular response. Insulin does not primarily function as any of these.

Conclude that insulin can function as a growth factor due to its ability to promote cellular growth and differentiation, in addition to its metabolic effects.
