Algae grow when they have the right conditions such as adequate nutrients (mostly phosphorus but nitrogen is important too), light levels, pH, temperature, etc. Generally the amount of phosphorus controls the amount of algae found in a freshwater lake or water body. The more nutrient-enriched a lake is, typically the more algae in the lake.

What exactly is the link between the extra glycogen associated with carbohydrate loading and enhanced performance in endurance s
Mashutka [201]

Options are not provided in the question. The complete question is:

What exactly is the link between the extra glycogen associated with carbohydrate loading and enhanced performance in endurance sports?

a. The extra glycogen serves as a reservoir for glucose, which serves as the main fuel molecule for increased cellular respiration, resulting in more available ATP.

b. The extra glycogen undergoes the process of deamination, which is the first step in the breakdown of the carbon chains needed for ATP synthesis.

c.The extra glycogen is used during beta oxidation, which is a series of chemical reactions resulting in the formation of acetyl coenzyme A, which is essential to start the citric acid cycle of aerobic cellular respiration.

d. All of the listed responses explain the link between carbohydrate loading and enhanced performance in endurance sports.

Answer:

a.

Explanation:

Glycogen is a multibranched polysaccharide of glucose which represents the main storage form of glucose in the body.

During sports, a lot of energy is required. The glycogen serves to fulfil all the enrgy requirement of the body. The extra glycogen associated with carbohydrate or glucose serves energy to cellular respiration due to increase in physical actvities and provide more ATP.

Hence, the correct option is a.
