Which of the following factors not effects photosynthesis
1 number, size, age and orientation of leaves
2 mesophyll cells and chromoplast
3 internal CO concentration and amount of chlorophyll
4 2 and 3
Explanation:
Photosynthesis is under the influence of several factors, both internal (plant) and external. The plant factors include the number, size, age and orientation of leaves, mesophyll cells and chloroplasts, internal \(\mathrm{CO} 2\) concentration and the amount of chlorophyll. The plant or internal factors are dependent on the genetic predisposition and the growth of the plant

Which functions as hydrogen donor in bacterial photosynthesis?
1 \(\mathrm{H}_2 \mathrm{O}\)
2 \(\mathrm{H}_2 \mathrm{~S}\)
3 \(\mathrm{HNO}_3\)
4 \(\mathrm{NH}_4\)
Explanation:
\(2 \mathrm{H}_2 \mathrm{~A}+\mathrm{CO}_2 \xrightarrow{\text { Light }} 2 \mathrm{~A}+\mathrm{CH}_2 \mathrm{O}+\mathrm{H}_2 \mathrm{O}\)
In green plants \(\mathrm{H}_2 \mathrm{O}\) is the hydrogen donor and is oxidised to \(\mathrm{O}_2\). Some organisms do not release \(\mathrm{O}_2\) during photosynthesis. When \(\mathrm{H}_2 \mathrm{~S}\), instead is the hydrogen donor for purple and green sulphur bacteria, the 'oxidation' product is sulphur or sulphate depending on the organism and not \(\mathrm{O}_2\).

Calvin cycle occurs in :
1 \(C_3\) plant
2 \(\mathrm{C}_4\) plant
3 CAM plant
4 All of these
Explanation:
Let us at the outset understand very clearly that the Calvin pathway occurs in all photosynthetic plants; it does not matter whether they have C3 or C4 (or any other) pathways.

When \(\mathrm{O}_2\) binds to RuBisCO the products in Calvin cycle is
1 2 Phosphoglycerate molecules
2 2 phosphoglycolate molecules
3 one phosphoglycerate and one phosphoglycolate molecule
4 2 Phosphoglyceraldehyde molecules
Explanation:
Here the RuBP instead of being converted to 2 molecules of PGA binds with \(\mathrm{O}_2\) to form one molecule and phosphoglycolate in a pathway called photorespiration.
