So here we will discuss about linear photophosphorylation and cyclic photophosphorylation.
00:06
So first we will discuss about linear photophosphorylation.
00:13
So what is linear photophosphorylation? it is the process, the process that uses light energy, that uses light energy to convert adp into atp to convert adp into atp and nadp plus and nadp plus into nadph into nadph.
01:08
So it involves the transfer of electrons, it involves the transfer of electrons, transfer of electrons from the water to nadp plus, from the water to nadp plus which produces oxygen as the by -product, which produces oxygen as the by -product that is linear photophosphorylation.
02:00
So next we will understand what is cyclic phosphorylation? cyclic photophosphorylation.
02:16
So cyclic photophosphorylation is the process, the process that uses light energy, uses light energy to convert adp into atp, to convert adp into atp but it does not produce nadph, but it does not produce nadph as it lacks nadph reductase enzyme, does not produce nadph.
03:11
It involves the transfer of electrons, it involves the transfer of electrons, transfer of electrons from photosystem i, from photosystem i that is psi back to psi that is in a cyclic manner back to psi which produces a proton gradient, which produces a proton gradient across the thylakoid membrane, across the thylakoid membrane.
04:32
So that is cyclic photophosphorylation...
