Question

after hydrogens and electrons are stripped from nadph, nadp⁺ is
multiple choice
○ recycled back to the light - dependent reactions.
○ sent to the electron transport chain of cellular respiration
○ broken down further to nad plus phosphate in the calvin cycle
○ sent to the krebs cycle

Explanation:

In photosynthesis, after NADPH donates hydrogens and electrons (e.g., in the Calvin cycle), \( \text{NADP}^+ \) is recycled back to the light - dependent reactions. The light - dependent reactions are responsible for regenerating \( \text{NADP}^+ \) into NADPH using light energy, electrons from water, and protons. The other options are incorrect: the electron transport chain of cellular respiration, Krebs cycle are part of cellular respiration (not directly related to the recycling of \( \text{NADP}^+ \) in photosynthesis), and \( \text{NADP}^+ \) is not broken down to NAD and phosphate in the Calvin cycle.

Answer:

A. recycled back to the light - dependent reactions
