Remember that lysis means to break apart, so glycolysis is a breaking down pathway. Glycolysis goes through a series of reactions in the cytosol to break down glucose into two 3-carbon pyruvates. In the process, it reduces some NAD to NADH - this is typical of catabolic redox reactions. These reactions require an investment of ATP but also make some ATP, so you get a net gain of 2 ATPs through glycolysis. The three carbon pyruvate goes through a reaction where it loses a carbon as CO2 to make a 2-carbon acetyl group, which gets added to CoA to make acetylCoA. AcetylCoA enters the mitochondrial matrix.

Hi! Doesn’t acetyl coA get produced in the mitochondria??

Video request please.... what is the healthiest fish for omega 3 and anti oxidants and other micronutrients without the mercury and microplastics risks. E.g. I heard that mackerel is good but varies depending on the specific species of mackerel. Also the ocean where the fish are caught has implications. It's quite confusing
