Glycolysis is : -Glycolysis (EMP pathway) is the first stage of respiration, taking place in the cytoplasm.
In it, one molecule of glucose (6C) is partially oxidised to two molecules of pyruvic acid (3C), with a net gain of 2 ATP and 2 NADH.
$C_6H_{12}O_6 \rightarrow 2CH_3COCOOH$ (+ 2 ATP + 2 NADH)
Conversion of pyruvate to acetyl CoA and then into citrate occurs in the mitochondria (Krebs cycle).
So glycolysis is the oxidation of glucose to pyruvate.
