HORTICULTURE

Detailed explanation-1: -The first process of this process is to entrap light. This step occurs as light reactions that involve photophosphorylation reactions involving photosystems I and II. The entrapped light is used in the formation of energy such as ATP and NADH.

Detailed explanation-2: -In photosystem II, enzymes absorb the photons of light to energise the electrons. The energised electrons then travel through a series of cofactors and coenzymes to reduce plastoquinone to plastoquinol. The energised electrons also replace the oxidising water to form molecular oxygen and hydrogen ions.

Detailed explanation-3: -Photosystem I and photosystem II are the two multi-protein complexes that contain the pigments necessary to harvest photons and use light energy to catalyse the primary photosynthetic endergonic reactions producing high energy compounds.
