Glucose Cells Blood Proteins Concentration Insulin Carrier Negative

When blood glucose rises, the pancreas releases insulin from beta cells, while alpha cells halt glucagon secretion. Insulin promotes glucose uptake by cells and its conversion to glycogen (glycogenesis), thereby lowering blood glucose.

This card describes the negative feedback for high blood glucose: the pancreas detects high levels, beta cells secrete insulin, and alpha cells stop glucagon release. Insulin acts on cells to increase glucose uptake and storage (glycogenesis), lowering blood glucose.

Front Negative feedback mechanism for when there is a rise in blood glucose concentration
Back Pancreas detect blood glucose concentration is too high

Beta cells secrete insulin 

Alpha cells stop secreting glucagon

Insulin secreted directly into blood

Insulin binds to receptors on cells

Change of shape of glucose carrier proteins so that they open and let more glucose in 

Increase the number of glucose transport proteins (Cells have vesicles of carrier proteins ready for glucose)

Cells respire more glucose

Glycogenesis activated
