Activity

  • Function:  Insulin decreases blood glucose concentration. It increases cell permeability to monosaccharides, amino acids and fatty acids. It accelerates glycolysis, the pentose phosphate cycle, and glycogen synthesis in liver.
  • Mechanism:  The species of elephant is not given, but it is most probably the indian elephant (Elephas maximus).
