Question

2. Explain how an organism such as a human regulates glycolysis and gluconeogenesis to minimize unnecessary utilization of resources

Answer 1

Glycogenesis is the formation of glycogen from glucose. If both glucose and ATP are present in relatively high amounts, then the excess of insulin promotes the glucose conversion into glycogen for storage in liver and muscle cells.

Glycolysis is the metabolic pathway that converts glucose into pyruvate, the free energy released in this process is used to form the high-energy molecules ATP and NADH.

Both glyclysis and glycogenesis take place in coordination with each other, wherever excess food is available human body converts it into glycogen and gets stored in liver, thereby wastage of energy is avoided and the same is used during shortage of food in body through glyclysis.
