Six-carbon sugars are the source of energy in organisms, related to the operation of life, and their degradation process is quite crucial.

Six-carbon sugars, with a six-carbon structure, are the key to energy generation in the way of metabolism of organisms. After organisms ingest six-carbon sugars, they are degraded and released through various biochemical reactions.

The process of glycolysis is first involved. Six-carbon sugars are in the cytoplasm and decomposed into three-carbon pyruvate after several steps of reaction. Although this process only produces a small amount of ATP, it is the foundation for subsequent energy metabolism.

Then, if the aerobic environment is suitable, pyruvate enters the mitochondria and is further degraded by the tricarboxylic acid cycle. In this cycle, pyruvate is completely oxidized, releasing a large number of energy carriers, such as NADH, FADH.

In addition, the produced NADH and FADH go through a series of redox reactions in the electron transport chain to transfer electrons, and at the same time drive protons to pump out to form a proton layer. The power of this proton layer prompts the operation of ATP synthase to generate a large amount of ATP, which provides energy for the organism.

The degradation of six-carbon sugars is fundamental to the energy supply of the organism, and has irreplaceable effects in maintaining life activities and supporting cell physiological functions. The mechanism of its fine regulation is also the focus of biochemical research, which is related to many aspects of biological health and disease.
