Question

1. nadp⁺ is an example of an electron carrier. describe its function in photosynthesis.

Explanation:

In photosynthesis, during the light - dependent reactions, electrons are excited in photosystems. \(NADP^{+}\) acts as an electron acceptor. It combines with electrons (\(e^{-}\)) and a hydrogen ion (\(H^{+}\)). The reaction is \(NADP^{+}+2e^{-}+H^{+}\to NADPH\). NADPH is then used in the light - independent reactions (Calvin cycle) as a reducing agent. It donates electrons to convert \(CO_{2}\) into organic molecules (e.g., glucose).

Answer:

\(NADP^{+}\) accepts electrons and \(H^{+}\) during the light - dependent reactions to form NADPH. NADPH is used in the Calvin cycle (light - independent reactions) as a reducing agent to convert \(CO_{2}\) into organic compounds.
