mention 5 characteristics of glycolysis
Answers
Answer:
Glycolysis has several important features:
1. It breaks down one molecule of glucose, a 6-carbon molecule, into two molecules of pyruvate, a 3-carbon molecule, in a controlled manner by ten or more enzymatic reactions. The oxidation of glucose is controlled so that the energy in this molecule can be used to manufacture other high energy compounds (see 2 and 3 below).
2. It makes a small amount of ATP, a process known as substrate-level phosphorylation. For each glucose molecule that is broken down by glycolysis, there is a net gain of two molecules of ATP.
3. It makes NADH (reduced nicotinamide adenine dinucleotide), a high energy molecule which can be used to make ATP in the electron transfer chain (see below). For each glucose molecule that is broken down by glycolysis, there is a net gain of two molecules of NADH.
4. It makes compounds which can be used to synthesize fatty acids. In particular, some of the carbohydrate intermediates of glycolysis are used by other enzymatic reactions to synthesize fatty acids, the major constituents of lipids, important energy storage molecules.
5. Glycolysis is the most important pathway, Most of the energy used by cells comes from glucose. It is the first pathway that is used to convert glucose into energy. It is one of the ancient pathways that is seen as it is used by all living organisms.
