Final Answer:
The basic outline of glycogen metabolism involves regulation based on high and low energy states, hormonal influence by insulin and glucagon, and peptide hormones orchestrating glycogen metabolism. Glycogen phosphorylase is activated through phosphorylation. The answer is d. Glycogen phosphorylase is ACTIVATED when phosphorylated.
Step-by-step explanation:
The basic outline of glycogen synthesis and breakdown involves intricate regulation correlating with high and low energy states. Insulin and glucagon, pancreatic hormones, play pivotal roles. In high energy states, insulin stimulates glycogen synthesis, promoting glucose storage. In low energy states, glucagon stimulates glycogen breakdown, releasing glucose for energy.
Peptide hormones, such as insulin and glucagon, orchestrate glycogen metabolism, ensuring glucose homeostasis. Notably, glycogen phosphorylase is activated when phosphorylated, enhancing glycogen breakdown. This activation is regulated by hormonal signals, with phosphorylation acting as a key step in response to signals indicating the need for increased energy availability, aligning with the dynamic demands of the body's energy requirements.
