New cards

After eating:

Insulin release from pancreas

Glucose high in blood, uptake into cells

Glycolysis starts

Gluconeogenesis stops

Glycogen breakdown stops in liver, kidney

Glycogen synthesis begins in liver, kidney and skeletal muscle

6
New cards

Fasting:

Glucagon release from pancreas

Glucose low in blood, uptake low in cells

Glycolysis stops

Gluconeogenesis starts in liver

Glycogen breakdown starts in liver, kidney

Glycogen synthesis stops
