WebChlorophyll cannot absorb green light and so instead reflects it making leaves look green. 3.8.5 State that light energy is used to produce ATP, and to split water molecules (photolysis) to form oxygen and hydrogen. Light energy is used to produced ATP and to split water molecules (photolysis) to form oxygen and hydrogen. WebChlorophyll is the main site of light absorption in the light dependent stage of photosynthesis There are a number of different chlorophyll molecules, each with their own distinct absorption spectra (the spectrum of light absorbed by a substance)
WebPlants need light, carbon dioxide, water and chlorophyll pigments in leaf for photosynthesis. Question 2: What is the use of light in photosynthesis? Аnswer: In the presence of light, photolysis reaction takes place in a plant. In photolysis reaction, the water decomposes to form hydrogen and oxygen gas. Question 3: Web(i)€€€€€ the role of chlorophyll in photolysis; (3) (ii)€€€€ how the energy of light is converted into chemical energy in the light-dependent
WebThe Role of Chlorophyll in Photosynthesis. The pigments of plants trap light energy and store it as chemical energy. They do this by catalyzing an oxidation-reduction process in … Web26 Nov 2024 · photolysis of water produces protons, electrons and oxygen.

WebChloroplasts are membrane-bound plastids containing chlorophyll, thylakoids, grana, and their own set of DNA molecules dispersed in the stroma. Each component of a chloroplast has a unique role in photosynthesis and photorespiration. ... Photolysis of water occurs in PS II, and it involves the dissociation of two water molecules to oxygen ...
Web25 May 2024 · Chlorophyll, which is present in the photosystems, soaks up light energy. The energized electrons are then used to make NADPH. The electron transport chain is a series of molecules that accept or donate electrons easily. By moving step-by-step through these, electrons are moved in a specific direction across a membrane.
