<prompt> Number of ATPs produced from adipose tissue from 1 NADH NAD NADH through respiratory chain:0 ATP1 ATP2 ATP2.6 ATP  <response>: Ans : D 2.6 ATP and , .Because of these inequalities, the cellular reduction potentials of these two pyridine nucleotides are not equivalent, and under prevailing cellular conditions, the NADPNADPH couple is a much better electron donating system than the NADNADH couple. Because each NADH is worth 2.5-3 ATP, each NADPH can be assigned a value of 3.5-4 ATP.
