<prompt> TCA is not controlled byNADHATPNADPHADP  <response>: There are 3 NADH molecules generated during one cycle, each of them will give rise to 2 12 ATPs on oxidation by electron transpo chain ETC; so altogether they will give 3 x 2 12 7 12 7.5 high energy phosphates. The FADH2 will generate 1 12 molecules of ATP. In addition, one molecule of GTP equivalent to one molecule of ATP is formed by substrate-level phosphorylation. Hence, per turn of the cycle, 10 high energy phosphates are produced. Hence NADPH is note controlled.Ref: DM Vasudevan, 7th edition, page no: 250
