Detailed explanation-1: -Aerobic Glycolysis This pathway requires oxygen to produce ATP, because carbohydrates and fats are only burned in the presence of oxygen. This pathway occurs in the mitochondria of the cell and is used for activities requiring sustained energy production.
Detailed explanation-2: -With oxygen, organisms can break down glucose all the way to carbon dioxide. This releases enough energy to produce up to 38 ATP molecules. Thus, aerobic respiration releases much more energy than anaerobic respiration.
Detailed explanation-3: -Aerobic respiration involves four stages: glycolysis, a transition reaction that forms acetyl coenzyme A, the citric acid (Krebs) cycle, and an electron transport chain and chemiosmosis.
Detailed explanation-4: -There are three stages of the aerobic energy system pathway, Glycolysis (we mentioned this last week), the Krebs cycle (TCA), and the Electron Transport Chain (ECT). Each stage can work to produce a more significant amount of energy. However, the time taken to do so is significantly longer than the anaerobic systems.
