Question

Give comparison between the following: Cyclic and non-cyclic photophosphorylation

Answer 1

$\begin{array}{ccc}\text{Criteria}& \text{Cyclic photophosphorylation}& \text{Non-Cyclic photophosphorylation}\\ \text{Location}& \text{This process occurs inside the stroma lamellae and involves only photosystem I.}& \text{This pathway involves both photosystems and occurs in the thylakoid membrane.}\\ \text{Energy molecules produced}& \text{Only ATP is produced}& \text{Both ATP and NADPH are produced.}\\ \text{Photolysis of water}& \text{No photolysis of water takes place to refill the electrons of the reaction center}& \text{Electrons are restored in the reaction center by the electron from photolysis of water}\\ \text{Oxygen production}& \text{No oxygen is produced}& \text{Oxygen is produced}\end{array}$
