When one CO2\mathrm{CO}_2 molecule is fixed as one molecule of triose phosphate, which of the following photochemically made, high energy chemical intermediates are used in the reduction phase?

Options

  1. A1 ATP +1 NADPH
  2. B1 ATP +2 NADPH
  3. C2ATP+1NADPH2 \mathrm{ATP}+1 \mathrm{NADPH}
  4. D2 ATP +2 NADPH

Correct answer

A. 1 ATP +1 NADPH

Step-by-step solution

During C3\mathrm{C}_3 cycle (calvin cycle) 3 phases continue, namely carboxylation, Reduction \& regeneration. During reduction or fixation phase, each CO2\mathrm{CO}_2 molecule require one mole of ATP and one mole of NADPH.
