The step of regeneration during \({C_4}\) pathway occurs in?
1 Bundle sheath cells
2 Only mesophyll cells
3 Epidermal cells of leaves
4 Both 1 and 3

The enzyme PEPcase is found in which cells?
1 Bundle sheath cells
2 Mesophyll cells
3 Bulliform cells
4 All of these
Explanation:
The enzyme that catalyses the \(C{O_2}\) fixation of PEP is PEP carboxylase or PEPcase. PEP is present in mesophyll cells hence, PEPcase is present in the cytoplasm of mesophyll cells.

Hatch and Slack pathway is otherwise known as \({C_4}\) - cycle because -
1 The primary \(C{O_2}\) acceptor is OAA, has 4 carboxylic acid
2 The first stable product is oxaloacetic acid OAA which is a \({C_4}\)-compound
3 All intermediate metabolites are \({C_4}\)-compounds
4 Because after 4 times of observation they found the pathway
Explanation:
The Hatch and Slack pathway is also known as \({C_4}\) cycle because the first stable product formed i.e. Oxaloacetic acid is a \({C_4}\) acid, containing 4 carbons.

The additional number of ATP molecules required by \({C_4}\) plants for one glucose molecule produced in comparison to \({C_3}\) plants is?
1 6
2 12
3 24
4 18
Explanation:
For the formation of one glucose molecule, \({C_3}\) plants require 18 ATP (3*6 turns of cycle) whereas \({C_4}\) plants require a total of 30 ATP (5* 6 turns of cycle). A difference of 12 ATP molecules exists.
