Detailed explanation-1: -The first step in photosynthesis is the photo excitation of chlorophyll by a photon of light.
Detailed explanation-2: -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. This energy is used to process various biosynthesis reactions.
Detailed explanation-3: -Light dependent reaction involves four important stages – absorption of light energy, splitting of water molecules, release of oxygen, formation of energy carrying molecules – ATP and NADPH.
Detailed explanation-4: -Steps of the Light Reactions The light reactions occur in several steps, all of which take place in the thylakoid membrane. 0 Step 1: Units of sunlight, called photons, strike a molecule of chlorophyll in photosystem II of the thylakoid membrane.
Detailed explanation-5: -In the first part of photosynthesis, the light-dependent reaction, pigment molecules absorb energy from sunlight. The most common and abundant pigment is chlorophyll a. A photon strikes photosystem II to initiate photosynthesis.
