Verified step by step guidance

Understand the role of insulin: Insulin is a hormone produced by the pancreas that plays a key role in regulating blood glucose levels. It facilitates the uptake of glucose into cells, thereby decreasing blood glucose concentration.

Identify the effects of insulin: Insulin increases the rate of fatty-acid synthesis and storage, decreases blood glucose concentration, and stimulates cell growth and division. These are well-documented effects of insulin in the body.

Analyze the given options: Review each option to determine if it aligns with the known effects of insulin. The first three options are consistent with insulin's functions.

Consider the incorrect statement: The statement 'It stimulates the release of proinsulin from the pancreas' is not an effect of insulin. Proinsulin is a precursor to insulin, and its release is not stimulated by insulin itself.

Conclude the analysis: Based on the understanding of insulin's functions, the statement about stimulating the release of proinsulin is the one that does not describe an effect of insulin.
