Evaluate the impact of PKB on glycogen synthesis in insulin signaling.

• A. PKB inactivates GSK, allowing glycogen synthase to remain active and promote glycogen synthesis.
• B. PKB has no effect on glycogen synthesis.
• C. PKB activates GSK, which inhibits glycogen synthase, reducing glycogen synthesis.
• D. PKB directly phosphorylates glycogen synthase, inhibiting its activity.

Answer: (A)
