Light Dependent Reactions The light dependent reaction of photosynthesis involves the transfer of sunlight energy into two things: The production of ATP Reduction of coenzyme NADP to NADPH NADP – Nicotinamide adenine dinucleotide phosphate NADPH – Reduced NADP The energy from sunlight is used to excite an electron‚ within a primary pigment‚ to a higher energy level. The excited electron is then donated to an electron acceptor leaving the chlorophyll molecule oxidised and reducing the acceptor

When it is night there is less light so the LDR has higher resistance and the light turns on. Explanation: When light shines on a Light Dependent Resistor‚ electrons are released and the current can get larger. So as the light intensity increases
