The correct option is (b)i.e, false that the entire process of glucose breakdown in the body occurs in the presence of oxygen.
The metabolic process that converts glucose into pyruvic acid is known as glycolysis. The high-energy molecules adenosine triphosphate and reduced nicotinamide adenine dinucleotide are created using the free energy released during this process. A series of ten enzyme-catalyzed processes make up glycolysis.
Another name for glycolysis is the EMP pathway. It is named after Embden, Meyerhof, and Parnas, the names of the discoverers. Because it is the metabolic process by which glucose produces cellular energy, glycolysis is significant. The most crucial source of energy for all living things is glucose. The great majority of cells in the human body chose glucose as their preferred fuel because only red blood cells can utilize it.
Fermentation is a process that allows glycolysis to occur in the absence of oxygen. The citric acid cycle, oxidative phosphorylation, and the other three phases of cellular respiration all require oxygen to function. In the cytoplasm of the cell, glucose is first broken down. This cellular respiration process is anaerobic, which means oxygen is not needed for it to occur.
