Question

A marathon runner is competing in a race. He has burned through his short-term energy stores and needs to tap into the energy stored in glycogen, a polysaccharide made up of glucose monomers that can be found in liver and muscle cells. What reaction would his cells perform to release the glucose monosaccharides from glycogen to provide him with energy?

Options:

A. Photosynthesis

B. Glycolysis

C. Glycogenolysis

D. Fermentation

Answer 1

The reaction to release glucose from glycogen for energy in a marathon runner is called glycogenolysis, which converts glycogen into glucose-1-phosphate and then to glucose-6-phosphate for ATP production.

Step-by-step explanation:

The cells would perform the reaction of glycogenolysis to release the glucose monosaccharides from glycogen and provide the marathon runner with energy. The reaction that a marathon runner's cells would perform to release glucose monosaccharides from glycogen to provide energy is called glycogenolysis. This process involves the hydrolysis of glycogen into glucose-1-phosphate monomers, which are then converted into glucose-6-phosphate. This glucose-6-phosphate can then enter the glycolytic pathway to be used for ATP production, which is vital for cells during periods of high energy demand such as a marathon.
