body has gone from using carbohydrates as its source of fuel to fats-almost exclusively. But it’s a little more involved than that. Ketosis starts when there aren’t enough carbohydrates in the blood stream to refill glycogen stores in your liver. What is glycogen? The liver makes glycogen from carbohydrates as a kind of quick food source for the body. A lack of carbohydrates means the body needs an alternate food source. So the body uses fat‚

* In Aerobic glycolysis‚ glucose or glycogen is broken down to pyruvic acid via glycolitic enzymes during carbohydrate metabolism. Hydrogen is released and glucose is metabolized to pyruvic acid. In the presence of oxygen‚ the pyruvic acid is converted into acetyl coenzyme A. (Acetyl CoA). 1 mole of glucose produce 2 moles of ATP or 1 mole of glycogen produces 3 moles of ATP. * In the Kreb Cycle system‚ once the acetyl CoA is formed‚ it enters

Your cells can also convert the components of lactose into the storage carbohydrate glycogen‚ which provides a supply of sugar for periods of fasting‚ Drs. Reginald Garrett and Charles Grisham expalin in their book "Biochemistry." You can also convert the sugars into fat Maltose A type of carbohydrate. Carbohydrates are one of the

whether it is weight loss or body building. During certain routing exercise training the body breaks down the glycogen. Primarily‚ glycogen is a sugar molecules from the food we eat and protein as well as fat too. Glycogen is the most available and willing to fuel our body the energy that we need to perform the exercise effectively. When our training exercise increases‚ the level of glycogen lessens dramatically and our body switches to fat and protein to fuel us with energy. As a result‚ we can break

and fat tissue to absorb glucose from your blood and store it as glycogen for future energy needs. Glucose is a form of sugar used by your body for energy‚ and is derived from the consumption of carbohydrates (e.g. starch). So you eat a donut‚ your body breaks it down‚ glucose is released into your blood‚ insulin is released as a reaction‚ and triggers your liver‚ muscles and fatty tissue to absorb this donut-derived glucose as glycogen for use down the road when you need it. So the

Muscle adaptations to the increase in energy demands at the start of exercise Introduction The transition from rest to exercise is associated with a huge upsurge in energy expenditure‚ due primarily to skeletal muscle contractions (Connett & Sahlin‚ 1996). Contractions require energy in the form of adenosine tri-phosphate (ATP). ATP stores in muscle are around 8mmol/l and are exhausted within 2s of exercise (Connett & Sahlin‚ 1996). To continue exercise and maintain ATP homeostasis‚ ATP

Describe the mechanisms by which muscle glycogen is broken down to glucose for use in glycolysis. Glucose is converted to glycogen in order to be stored in the liver and muscles to use at a later time. When the body is ready to use these glycogen stores for

good sugars and 400 become bad sugars during the digestion. These 500 sugars mix in the blood. Let us assume that there is no stored glycogen available in his body. What will happen now? The 100 good sugars will get insulin and enter into the cells. The 400 bad sugars will not get insulin and go out through the urine. Adrenal gland will search for glycogen. Since glycogen is not available‚ it will not be able to supply sufficient glucose to the cells. Since sufficient sugar is not supplied‚ the cells

Muscles contain large storages of complex carbohydrates called glycogens. Glycogens are the stored form of sugar found in our bodies. Through a complex series of chemical reactions glycogen breaks down into ATP as well as lactic acid. This system supplies ATP slower than the Phosphocreatine system. The body cannot produce enough ATP to maintain this energy source for longer
