In photosystem I, energy from sunlight<span> energizes a pair of electrons in the reaction center (replaced by a pair of electrons from photosystem II) and these are passed to molecules of NADP+ to reduce them to NADPH. This molecule carries the electrons (and potential energy) to the carbon reactions of photosynthesis.</span>
Answer:
Depends on molecule.
Explanation:
The number of the polypeptide chains present in the oligomer depends on the molecule. Some molecules have more polypeptide chains whereas some of them have less polypeptide chains. For example, Hemoglobin is a oligomer that consists of four Polypeptide Chains, two of these Polypeptide Chains are α-globin molecules, each comprise of 141 amino acids, and the other two are (β, γ, δ, or ε) globins, each consist of 146 amino acids.
