337060 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

BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337061 A plant is provided with ideal conditions for photosynthesis and supplied with isotope $^{14} {CO}_{2}$ . 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.

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.

337063 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.
