What is correct about Dark Reaction?
1 It is called Hill reaction
2 It is biochemical, enzymatic, depeding on light raection
3 It is independent of enzymes
4 All of these
Explanation:
Dark reaction thought light independent, requires products formed from light reaction. It uses various enzymes to carry out a series of reactions. Hence, it is also known as the biochemical phase of photosynthesis.

A plant is provided with ideal conditions for photosynthesis and supplied with isotope \({ }^{14} \mathrm{CO}_{2}\). When the products of the process are analysed carefully, what would be the nature of products?
1 Both glucose and oxygen are labelled.
2 Only oxygen is labelled but glucose is normal.
3 Both glucose and oxygen are normal.
4 Only glucose is labelled, and oxygen is normal.
Explanation:
Glucose will be labelled as the carbon that forms it will be derived from the carbon dioxide supplied which is the supplied isotope. Oxygen will not be labelled and is normal as the supplied oxygen is normal as well.

PEP is primary \(C{O_2}\) acceptor in
1 \({C_4}\) plants
2 \({C_3}\) plants
3 \({C_2}\) plants
4 Both \({C_3}\) and \({C_4}\) plants
Explanation:
Phosphoenol pyruvate (PEP) is present i n mesophyll cells and the primary \(C{O_2}\) acceptor in \({C_4}\) plants.

The similarity between \({C_3}\) and \({C_4}\) pathway is:
1 Both are equally efficient.
2 Organic acid is formed as the first product of \(C{O_2}\) fixation.
3 Both take place in mesophyll cell
4 Both takes place in light
Explanation:
In both the cycles, organic acid is formed as first stable product. Those plants in which the first product of \(C{O_2}\) fication is a \({C_3}\) acid (PGA), i.e., the \({C_3}\) pathway, and those in which the first product was a \({C_4}\) acid (OAA), i.e., the \({C_4}\) pathway.
2 It is biochemical, enzymatic, depeding on light raection
3 It is independent of enzymes
