Which of the following processes do not take place in the mitochondria? a) citric acid cycle b) conversion of pyruvate to activated acetyl groups c) oxidation of fatty acids to acetyl CoA d) glycogen breakdown

D

Explanation:

The breaking down of glycogen-glycogenolysis takes place in the cytosol of cells of the liver and muscles.it is the compensatory process for providing glucose depleted cells with extra glucose. It is the opposite of Glucogengenesis the formation of glycogen in cells.

it involves the activities of enzymes glycogen phosphorylase which catalysis the removal of alpha1-4glycosidic bonds from the glycogen molecules.Thus freeing the glucose molecules from the glycogen while retaining the 1-6 glycosidic bonds.

Its stimulation is by  epinephrine hormone.while  the hormones glucagon from the pancreas control its release into the blood stream,Thus the low levels of glucose in the blood stream caused glucagon to initiate  the breakdown of glycogen in the liver and muscles down to glucose.As the level of this rise in the blood stream Insulin stimulates the entry of the glucose into the cells reducing the levels of blood glucose,inhibiting glucagon levels ,and therefore stopping Glycogenolysis.
