the answer is that (<span>T</span>hey can spoil food)
Hello, I figured that the question was missing its options so I went online to find them. Here they are:
All of the following are true of the thymus gland, except that:
A) activates B cells.
B) reaches its greatest relative size during the second year of life.
C) involutes after puberty.
D) produces T cells.
E) lies in the anterior mediastinum
Answer:
The correct answer is: A) activates B cells.
Explanation:
The thymus is a lymphatic organ that is located in the anterior superior mediastinum (a compartment in the thoracic cavity), in front of the heart, with the function to mature T cells (one of the types of lymphocytes, white blood cells very important for the functioning of the immune system).
The thymus is more active and bigger during childhood, when puberty hits it involutes and its functional tissue is replaced with adipose tissue (fat).
<u>B cells are not activated in the thymus, they mature in the bone marrow</u>.
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.
