Glycolysis
`Glycolysis is the first stage which is a 10 – reaction biochemical pathway that produces ATP by substrate – level phosphorylation. Glycolysis occurs in the cytoplasm and converts into a 3 carbon molecule of pryruvate. Glycolysis begins with a 6 - carbon of glucose. Two energy phosphates from ATP molecules are added to the 6 – carbon molecule of glucose which produces a 6 – carbon molecule with two phosphates. Then the 6 – carbon molecule is split in half with 3 on each side with 1 phosphate attached.
In the second half of glycolysis, an additional inorganic phosphate is added into the 3 – carbon phosphate. The additional phosphate and the NAD+ come together and make NADH. Then it goes into a transfer, which is a reduction of ADP to ATP twice which comes out with a 3 – carbon pyruvate. ADP is converted to ATP through substrate level phosphorlyation. Which is 1 NADH and 2 ATP molecules. 4 ATP (2 ATP from each side) – 2 ATP (from the first step) = 2 ATP......
