process. The three stages are: glycolysis‚ citric acid cycle‚ and electron transport. What is the role of glycolysis? Include the reactants and the products. Where does it occur? Glycolysis is the sugar splitting process where the molecule is split in half outside of the mitochondria. The molecule NAD+ picks up electrons and hydrogen atoms from the carbon molecule and become NADH. ATP is produced from the process‚ as well as pyruvic acid. Glycolysis can occur with or without oxygen

* 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

remaining three glucose units are transferred to form a longer chain by glucotransferase which also hydrolyzes the alpha (1‚ 6) link to produce free glucose. Finally‚ phosphoglucomutase converts the free G1P to G6P. Free glucose and G6P can enter glycolysis in both the liver and muscle cells but in liver cells‚ free glucose can be transported into the bloodstream. Glucose-6-phosphotase‚ an enzyme not found in muscle cells‚ is needed to hydrolyze G6P into free glucose for transportation in the bloodstream

Premium Adenosine triphosphate Muscle Cellular respiration
Cellular Respiration Cellular respiration is basically what cells do to break down sugars into a form that the cell can utilize as energy. Cellular respiration takes in food and uses it to create ATP. ATP is a chemical which the cell uses for energy. The are two forms of cellular respiration‚ aerobic and anaerobic respiration‚ in which will be explained. Regular cellular respiration is aerobic‚ meaning that it requires oxygen‚ but some simple organisms can only do anaerobic cellular respiration‚

goals when wanting to become physically fit‚ but not many people know the difference between aerobic and anaerobic training. Even though aerobic and anaerobic training both contribute in maintaining overall health and both produce energy through glycolysis‚ which is the conversion of glucose into pyruvate‚ the training are different to achieve different results and the metabolic processes used by these two types of training are different. It is very important to know how to distinguish the differences

The plasma membrane of a cell is extremely important to the transportation of substances into and out of the cell. The outer membrane of a cell is made up of lipids and proteins. Most of the lipids in plasma membranes are phospholipids. The phospholipids have a hydrophilic head and two hydrophobic tails. When engulfed in water‚ they arrange themselves such that all the hydrophobic tails clump together‚ surrounded by the hydrophilic heads‚ protecting the tails from the exposure to the water. In cells

Define metabolism: The sum of all biological chemical reactions inside a cell or organism Differences in catabolism and anabolism: Catabolism is an enzyme-regulated chemical reaction that releases energy. Complex organic compounds such as glucose‚ amino acids‚ glycerol and fatty acids are broken down into simpler ones. The energy of catabolic reactions is used to drive the anabolic reactions. Anabolism is also enzyme regulated but requires energy for taking the simpler broken down components
