Review the basic principles of energy metabolism (Lectures on Glycolysis, Krebs Cycle, and Electron Transport Chain), and review ch 7+8 on the effects of exercise on energy metabolism and weight management.
Then, respond to the following question:
1. In 6-10 sentences, explain to an endurance athlete with a background in nutrition why he/she has higher carbohydrate needs compared to the average person. Use vocabulary from ch 1 and 7 in your response, and write to the athlete as if he/she has taken a biochemistry class. Make sure to discuss metabolic pathways including glycolysis, Krebs cycle, and electron transport chain in your response, as well as specific ways exercise, affects these pathways.
