MUSCLE PHYSIOLOGY

Detailed explanation-1: -Glycolysis is a universal catabolic pathway that converts glucose into pyruvate through a sequence of ten enzyme-catalyzed reactions, and generates the high-energy molecules ATP (adenosine triphosphate) and NADH (reduced nicotinamide adenine dinucleotide).

Detailed explanation-2: -Glycolysis, which literally means “breakdown of sugar, ‘’ is a catabolic process in which six-carbon sugars (hexoses) are oxidized and broken down into pyruvate molecules. The corresponding anabolic pathway by which glucose is synthesized is termed gluconeogenesis.

Detailed explanation-3: -Glycogenesis, in contrast, is the process of anabolic synthesis of glycogen. Glucose molecules are phosphorylated to glucose-6-phosphate, converted to glucose-1-phosphate and UDP-glucose, and added to glycogen chains for storage.

Detailed explanation-4: -Glycolysis is a catabolic process of glucose hydrolysis needed for energy and biosynthetic intermediates, whereas gluconeogenesis is a glucose production process important for maintaining blood glucose levels during starvation.
