BIOL4 Glycolysis QuestionWatch
My question is: seeing as triose phosphate has only 1 phosphate group attached, how is it that 2 ATP molecules are formed for every 1 triose phosphate molecule by substrate-level phosphorylation? Are both molecules even formed by substrate-level phosphorylation?
Substrate level phosphorylation is when a phosphate group on a donor molecule is transferred to ADP to make ATP. If two ATP molecules are made, two phosphate groups are transferred. Triose phosphate has only 1 phosphate group (I believe?) so it can't donate two phosphate groups. Help?
