4.5- regulation of blood glucose

• Glucose comes from starches and sugars which is from what humans eat
• glucose creates glycogen which is found in the liver and muscle tissue
• glucosegenesis is the process of converting glucose into glucose
• glucose level can change extremely fast
• hypoglycaemia

  • sweating
  • lack of coordination
  • sleepy
  • irritability
  • hunger
• hyperglycaemia

  • dry mouth
  • thrust
  • weakness
  • headache
  • frequent ruination
  • blurry vision
• when blood sugar levels fall below normal, secretion of glucagon increases and insulin stops
• when blood glucose rises above average secretion of insulin rakes place and glucagon stops.
• glucagon is in the liver
• insulin is released when there is an above normal rise in blood level. It does the following:

  • stimulating the movement of glucose from blood into sketal and adipase.
  • activating enzymes that make glucose into glucagon
  • inhibiting the break down of fats
• glucagon is stored in granules
• glucagon is stored in granules
• glucagon targets the liver and binds to receptors on liver cells and by releasing glucose aims to raise it by breaking down in glucagon and making glucose.
• after food, blood sugar levels rise
• when blood glucose gets low it breaks down glucagon to glucose and makes new glucose
• whereas when blood sugar levels are too high, insulin binds to receptors on the plasma membranes of the skeletal and adipose cells and leads to glucose beings transported into those cells making it be less.
• skeltal converts glucose into glucagon
• ain the liver insulin activates enzymes in lover cells that build glucose.
• Skeletal Cells


  Skeletal cells or muscle cells use glucose as a source of energy.
• Insulin Binding


  Insulin binds to receptors on the plasma membranes of skeletal and adipose cells, triggering glucose transport into those cells.
