22. Insulin in the bloodstream is a response to increased blood glucose, and: (A) stimulates gluconeogenesis, (B) inhibits glycolysis, (C) stimulates glycogen synthesis in muscle and liver, (D) stimulates glycogen breakdown in liver, (E) inhibits phosphoprotein phosphatase-1.

複選題23. Which of the following can be used as a substrate for gluconeogenesis in the liver? (A) alanine, (B) glutamic acid, (C) glycerol, (D) succinate, (E) all of the above.
