Lipid metabolism entails the oxidation of fatty acids to either generate energy or synthesize new lipids from smaller constituent molecules. In stage II of catabolism, the metabolic pathway known as glycolysis converts glucose into two molecules of pyruvate (a three-carbon compound with three carbon atoms) with the corresponding production of adenosine triphosphate (ATP). During the first stage of respiration, molecules of glucose are broken down into smaller molecules, and a small amount of energy is released during the second stage, the small molecules are broken down to even smaller molecules. Glycolysis. The large organic molecules of organic chemistry, such as lipids, proteins, and polysaccharides, are digested into their outside cells' smaller components. Here, the smaller molecules from glucose are broken down further and, in combination with oxygen, make the end products of cellular respiration carbon dioxide, water, and energy. 2. Krebs Cycle Definition. Stage 3: These precursors are assembled into complex molecules like proteins, polysaccharides ... which is subsequently transformed into glucose. The stages of glucose breakdown can be divided into four distinct phases. • Glucose is broken down into smaller molecules. It literally means ‘splitting sugars’. One can think of glycolysis as having two phases that occur in the cytosol of cells. For instance, phosphoenolpyruvate (PEP), an intermediate, can be used to make several amino acids. Explanation: In this step, enzymes split a molecule of glucose into two molecules of pyruvate, which releases energy that is transferred to ATP. Aerobic respiration is divided into three main stages: Glycolysis, Krebs cycle and Electron transport chain. The secretion of α-amylase in the small intestine converts any remaining starch molecules, as well as the dextrins, to maltose. Metabolism is the sum of all of the chemical reactions that are involved in catabolism and anabolism. In stage two, the pyruvate molecules are transported into the mitochondria.
