Answers
Answer Glycolysis or glyco-decomposition is the first stage of respiration that occurs in the cell fluid. In this activity, there is partial oxidation of glucose, as a result 2 molecules of pyruvic acid are formed from one molecule of glucose and some energy is released. This action takes place in several stages and acts as a specific enzyme catalyst in each step. This action is also called INP Pathway. In this, 4 percent of the energy stored in glucose is freed and goes to NADH2 and the remaining 96 percent energy is stored in pyruvic acid. The reaction of glycolysis takes place in the matrix of mitochondria, the process of glycosis starting from glucocose to pyruvate via various intermediate metabolites. Each chemical change (red box) is carried out by a different enzyme. ATP (blue) is consumed in steps 1 and 3 and ATP (yellow) is formed in steps 7 and 10. Since steps 6–10 occur twice for each glucose molecule, this causes net
The process of generating energy as a result of oxidation of food in living cells is called cellular respiration. It is a catabolic activity that can occur in both the presence or absence of oxygen. The energy released during this activity is stored and stored in a biomolecule called ATP, which is used by organisms in their various biological functions. This biochemical activity occurs every day and night in the cells of both plants and animals. Cells use glucose, amino acids and fatty acids as food substances to oxidise the atom of oxygen to take electrons. There is an integral relationship between cellular respiration and breathing, and these two activities complement each other. Breathing occurs between the living organs and their environment. During this, oxygen and carbon dioxide gas are exchanged between the living and their environment and by this action the oxygen gas reaches the respiratory organs of living organisms. Oxygen gas enters the blood by diffusion from the respiratory organs. Blood is the medium of transport that carries this oxygen to the cells of different parts of the body. There cells use it in their cellular respiration. Respiratory activity occurs in the cytoplasm and mitochondria of each living cell. Respiratory preparatory functions occur in the cytoplasm and the remaining functions in the mitochondria. Since most of the energy is produced in the last phase of the action itself. Therefore, mitochondria are called the cell's respiratory or power house.
