When Does Catabolism Occur?

Catabolism is what happens when you digest food and the molecules break down in the body for use as energy. Large, complex molecules in the body are broken down into smaller, simple ones. An example of catabolism is glycolysis. This process is almost the reverse of gluconeogenesis.

Why does muscle catabolism occur?

When you exercise at high intensity for over 60 minutes, you stress your body intensely and as a result the hormone cortisol is excreted from the adrenal glands, a hormone that breaks muscle tissue into energy production.

Where do catabolic reactions occur?

Catabolic reactions are a type of metabolic reaction that take place within a cell. Larger molecules are separated to form smaller molecules, as in the case of respiration where glucose is broken down to form carbon dioxide and water.
