What is photolysis and mention its importance in photosynthesis?

Answer 1

Photolysis is any reaction where a chemical compound splited by photon (units of light). In a lay man's language splitting up a chemical compound in presence of light. In photosynthesis photons split water molecule into its constituents and release energy in the form of electrons which are transported to the electron transport chain along electopotential gradient

The reaction is a s follows

H2A + 2 photons (light) 2e- + 2H+ + A

A can be oxygen or in purple sulfur or cyanobacteria can be S

Answer 2

photolysis is using the energy from light to split a Hydrogen atom into a H+ (proton) and an e- (electron). It is the first step in the light-dependant reaction of photosynthesis- without it, this reaction cannot occur indefinately. The e- enters the electron transport chain, where the redox reactions release some energy.

Answer 3

chemical process by which molecules are broken down into smaller units through the absorption of light

Answer 4

The process of breakdown of water molecules into hydrogen and oxygen by the influence of light during the light reactions of photosynthesis.
