How do glycogen stores in muscle impact athletic performance and recovery?
Glycogen stores in muscle serve as a crucial energy source during physical activity. Depleted glycogen levels can lead to fatigue and decreased performance. Adequate glycogen stores support sustained energy levels, allowing athletes to perform at their best and recover more effectively after intense exercise.
How much time is usually needed in intense activity to cause depletion of glycogen glucose?
Intense activity can deplete glycogen stores within 60-90 minutes, depending on the individual's fitness level, intensity of the activity, and glycogen stores before exercising. Replenishing glycogen stores through carbohydrate consumption after intense exercise is crucial for optimal recovery and performance.
Glycogen and lipids are stored?
Glycogen is stored in the liver and muscles as a short-term energy reserve, while lipids are stored in adipose tissue as a long-term energy reserve. Glycogen can be quickly broken down into glucose for energy, while lipids provide a more sustained source of energy over time.
How does the body utilize ATP glycogen during physical activity?
During physical activity, the body uses ATP (adenosine triphosphate) stored in muscles for immediate energy. If the activity continues, the body breaks down glycogen stored in the muscles and liver to produce more ATP for sustained energy.
What breaks down glycogen in the body?
The enzyme called glycogen phosphorylase breaks down glycogen in the body.
Which of the following is not a characteristic of caffeine used in physical activity?
It slows depletion of muscle glycogen Nutrition 200~jm~
Depletion of stored glycogen causes?
fatigue....
Which of the following statements about glycogen phosphorylase (GP) is incorrect?
AMP is an inhibitor of glycogen phosphorylase.
Which of the following would be used as energy in the human body source only after depletion of other sources glycogen in muscle cells calcium phosphate in bones glucose in the blood protein in mu?
glucose is the most efficient form of "food." Glucose would be used first. Protein in muscles will only be broken down in extreme starvation. As for the other answers, glucose is the energy source of choice and is the first to be broken down. Glycogen becomes the predominant energy source and glucose levels become depleted. Calcium phosphate cannot be used to generate ATPs in the body in any way.

What happens when the liver has no glycogen reserve?
total absence of glycogen in the liver may be rare but rather an abnormally low levels of glycogen is more common. This could be as a result of an impairment in any of the enzymes involved in glycogen synthesis. Now, when glycogen is low,the body will look for another source of energy. The next immediate source is fatty acid . Hence low glycogen levels will lead rapid breakdown of fatty acids which when it becomes continuous can cause weight loss.. but the brain poorly utilizes fatty acids for energy production... hence a continous depletion of glycogen levels may result in some neurological impairments..

Which of the following is a characteristic of glycogen synthesis after a bout of strenous training?
Glycogen repletion is enhanced most by eating foods w/a high glycemic index Nutrition 200~jm~
Which of the following enzymes is not required to breakdown glycogen into glucose-6-phosphate molecules for further metabolism?
All of these enzymes are necessary in the breakdown of glycogen into glucose-6-phosphate molecules.
Which one of the following can store the largest total amount of Glycogen in the human body?
Skeletal muscle
