C4 Cycle Hatch Slack Pathway

In the leaves of C₄ plants, malic acid formation during CO₂ fixation occurs in the cells of:
1. mesophyll
2. bundle sheath
3. phloem
4. epidermis

C₄-plants are more efficient in photosynthesis than C₃-plants due to:

1.	higher leaf area
2.	presence of larger number of chloroplasts in the leaf cells
3.	presence of thin cuticle
4.	lower rate of photorespiration

Phosphoenol pyruvate (PEP) is the primary CO₂ acceptor in:
1. C₄ plants
2. C₂ plants
3. C₃ and C₄ plants
4. C₃ plants

Which of the following statements is incorrect?

1.	RuBisCO is a bifunctional enzyme
2.	In C4 plants, the site of RuBisCO activity is mesophyll cell
3.	The substrate molecule for RuBisCO activity is a 5-carbon compound
4.	RuBisCO action requires ATP and NADPH

The first stable product of CO₂ fixation in sorghum is:

1. Succinic acid

2. Phosphoglyceric acid

3. Pyruvic acid

4. Oxaloacetic acid

Given below are two statements:

Statement I:	The primary acceptor in plants is phosphoenolpyruvate and is found in the mesophyll cells.
Statement II:	Mesophyll cells in plants lack RuBisCO enzyme.

In the light of the above statements, choose the correct answer from the options given below :

1.	Statement I is incorrect but Statement II is correct.
2.	Both Statement I and Statement II are correct.
3.	Both Statement I and Statement II are incorrect.
4.	Statement I is correct but Statement II is incorrect.
