Which of the following pathways directly provides oxidizable substrate to red blood cells during the fasted state? a. glycogenolysisb. β-oxidation c. ketogenesis d. protein catabolism

a. Glycogenolysis

Explanation:

Glycogenolysis

It is a biochemical pathway for the breakdown of glycogen to glucose , it takes place in the muscle cells and in liver tissues .

glycogenolysis have a very important role in the regulation of glucose level in the blood .

The red blood cells lacks in the mitochondria and will oxidize the glucose under both the fasted conditions .

Hence the pathway is Glycogenolysis .

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
