17: Describe the regulation of hexokinase/glucokinase, phosphofructokinase-1 (PFK-1), and pyruvate kinase in glycolysis

18: Describe the synthesis and release of insulin from beta cells

Answer 1

15: Describe the role of anaerobic glycolysis in the red blood cell

Anaerobic glycolysis is the transformation of glucose into lactate in limited supply of oxygen. Due to the presence of haemoglobin in the red blood cells they lack mitochondria which produce energy for the cell. So red blood cells metabolize glucose mainly by anaerobic glycolysis which gives lactate as an end product, which then releases from the cell yeilding 2 ATP for each glucose molecule. In short anaerobic glycolysis provides energy to red blood cells.
