When one 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. C2 ATP +1 NADPH
  4. D2 ATP +2 NADPH

Correct answer

A. 1 ATP +1 NADPH

Step-by-step solution

During C ₃ cycle (calvin cycle) 3 phases continue, namely carboxylation, Reduction & regeneration. During reduction or fixation phase, each CO ₂ molecule require one mole of ATP and one mole of NADPH.
