Which statement accurately describes what occurs in photosystem II?

Group of answer choices

Light energy excites electrons in the electron transport chain in a photosynthetic unit.

The photons are passed along to a molecule of P700 chlorophyll in the photosynthetic unit.

The P680 chlorophyll donates a pair of protons to NADPH, which is thus converted to NADP+.

The electron vacancies in P680 are filled by electrons derived from the splitting of water.

The splitting of water yields molecular carbon dioxide as a by-product.

Solutions

Expert Solution

The P680(Photosystem 2) is a component of the non cyclic photophosphorylation which is connected to P700 via Electron Transport System. Upon excitation by light energy (photons) the electron travels through a series of components generating ATP & NAPDH.

Hope you'll understand the concept. Please like. Thankyou
