Homework Answers
Answer: Photophosphorylation is a process of photosynthesis, where ADP is phosphorylated to form ATP using energy from sun light. It is of two type, cyclic electron photophosphorylation and non-cyclic photophosphorylation.
The difference between cyclic electron photophosphorylation and non-cyclic photophosphorylation in given aspects are shown in the following table.
|
Aspects |
Cyclic phosphorylation |
Non-cyclic phosphorylation |
|
a. Types of photosystems involved |
It involves only Photosystem I (PS I) |
It involves both Photosystem I (PS I) and Photosystem II (PSII) |
|
b. Patterns of electron flow |
Electrons flows in circular/Cyclic pattern |
Electrons flows in non-cyclic pattern. |
|
c. Type of energy produced |
ATP |
ATP and reducing coenzymes (NADPH) |
|
d. Type of energy used |
Sun light-Low light intensity |
Sun light-High light intensity. |
|
e. Water splitting |
Water splitting does not occur. |
Water splitting (Photolysis of water) occurs. |
