How many molecules of ATP are produced directly in the TCA cycle...

How many molecules of ATP are produced directly in the TCA cycle from the breakdown of glucose?

Options

  1. AOne
  2. BTwo
  3. CThree
  4. DFour

Correct answer

B. Two

Step-by-step solution

We have till now seen that glucose has been broken down to release CO₂ and eight molecules of NADH + H⁺ ; two of FADH2 have been synthesised besides just two molecules of ATP in TCA cycle. You may be wondering why we have been discussing respiration at all – neither O₂ has come into the picture nor the promised large number of ATP has yet been synthesised. Also what is the role of the NADH + H⁺ and FADH2 that is synthesised?
