Question 23
Some of these terms / chemicals are asociated with the C4 cycle. Explain.
(a) Hatch Slack pathway (b) Calvin cycle
(c) PEP carboxylase (d) Bundle sheath cells
The terms associated with C4 cycle are
Hatch Slack Pathway - The process of synthesis of glucose in C4 plants is different from C3 plants which was discovered by two scientists MD Hatch and CR Slack (1977). Hence, named the Hatch-Slack pathway.
PEP Carboxylase - It is an enzyme present in mesophyll cells of C4 plants. It fixes CO2 to form 4-carbon compound, i.e., oxaloacetate (OAA).
Bundle Sheath Cells - These are specialised sclerenchymatous cells present around the vascular bundle, in the veins of monocot leaves. These have agranal chloroplast. C3 cycle occurs in these cells to manufacture glucose in C4 plants.
Calvin Cycle - This cycle operates in bundle sheath cells and fixes CO2 to form glucose molecules.
