• Physiological Effects of Insulin:
• Insulin is an anabolic peptide hormone synthesized and secreted by the $\beta$-cells of the pancreatic islets (Brockmann bodies in teleost fishes) in response to hyperglycemia and aminoacidemia.
• Induction of Glycogenesis:
• Insulin dephosphorylates and activates glycogen synthase while simultaneously inactivating glycogen phosphorylase, promoting the conversion of intracellular glucose into glycogen stores in liver and muscle.
• It suppresses counter-regulatory catabolic pathways: glycogenolysis and gluconeogenesis.
• nalysis:
• (Glycogenesis): Correct.

Correct option: (2) Glycogenesis
