Content: State the normal levels of blood glucose, outline hypoglycemia & hyperglycemia, explain transportation of glucose Language: Read and Write about blood glucose and its transport Share in cooperative groups about blood glucose and its transport

Objectives:

01. RESUME

Normal levels of blood glucose at rest

The human body normally keeps blood glucose levels very stable at 4.mmol/L - 4.5 mmol/L

Hypoglycemia

• Also known as low blood sugar this is caused by skipping a meal, excessive exercise,
• In diabetics it causes high insulin levels

Hyperglycemia

• Also known as high blood sugar this usually develops slowly. It can take several hours or days
• Infections can cause this
• In diabetics it causes low insulin levels

TRANSPORTATION OF gLUCOSE

glut 4 & glut 1: pROTEINS IN CHARGE OF THE TRANSPORT OF GLUCOSE IN THE CELLS

whERE

Muscle fibers contain GLUT 1 and GLUT 4 proteins to move glucose into muscular cells

At Rest

Most glucose will travel through the GLUT1 transporters

GLUT 4 AT REST

GLUT 4 transporters are inside intracellular vesicles they allow for greater glucose movement into the cell this is stimulated at rest after eating and there is a rise in insulin

GLUT 4 During physical activity

They will be stimulated without insulin during physical exercise this is due to the stimulation of calcium ions.
