Cellular respiration generates a total of 36-38 atp molecules. how many of these come solely from glycolysis?

Glycolysis is breakdown of glucose by enzyme
4 ATP In ETS
 from 2 (NADH+H) - 6 ATP From FADH2 - no any ATP
so ATP consumed -2
total ATP
=4+6-2=8
8 come from glycolysis

Iwould say silver and gold
