Blood Sugar Regulation

Insulins job is to

• Bind to receptors and open the glucose channels so glucose can enter cells

• Bind to the glucose carriers so glucose can enter cells

• Bind to receptors and open the glucose carriers so glucose can enter cells

• Bind to receptors so glucose can enter cells

POLYSACCHARIDE (sugar) that is stored in the liver (and muscles) for an emergency energy supply.

• glucose

• glycogen

• glucagon

• sucrose

When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels. This is an example of a:

• Positive Feedback Loop

• Negative Feedback Loop
