The first stable product of \(C{O_2}\) fixation in sorghum is:
1 Pyruvic acid
2 Oxaloacetic acid
3 Succinic acid
4 Phosphoglyceric acid
Explanation:
Oxaloacetate (OAA), malate, and aspartate (Asp) are substrates for the \({C_4}\) acid cycle that underpins the \(C{O_2}\) concentrating mechanism of \({C_4}\) photosynthesis. In this cycle, OAA is the immediate, short-lived, product of the initial \(C{O_2}\) fixation step in \({C_4}\) leaf mesophyll cells

In the maize plant, \(\mathrm{CO}_{2}\) fixation occurs in both mesophyll and bundle sheath cells. The enzymes involved in these cells for the process respectively are:
1 RuBisCo and PEP kinase
2 PEP kinase and Pepsin
3 RuBisCO and PEP carboxylase
4 PEP carboxylase and RuBisCO
Explanation:
In the leaf of \(\mathrm{C}_{4}\) plant, two distinct photosynthetic tissues are present - bundle sheath and mesophyll cells, it is called Kranz anatomy. The carbon dioxide that enters the mesophyll cells is accepted by a 3-carbon molecule called phosphoenol pyruvate (PEP). The enzyme phosphoenol pyruvate carboxylase (PEPcase) catalyses the carboxylation of PEP to 4-carbon acid oxaloacetic acid. Oxaloacetate is then converted to a similar molecule, malate, that can be transported in to the bundle-sheath cells. Inside the bundle sheath, malate breaks down, releasing a molecule of \(\mathrm{CO}_{2}\). The \(\mathrm{CO}_{2}\) is then fixed by rubisco and made into sugars via the Calvin cycle.

The given diagram represents the Hatch and Slack pathway. Name the \(C{O_2}\) acceptor (A) and first stable product (B) of \({C_4}\) cycle respectively.
1 A - Phosphoglyceric acid, B - Phosphoenol pyruvate
2 A - RuBisCO, B - Phosphoglyceric acid
3 A - RuBisCO, B - Oxaloacetic acid
4 A - Phosphoenol pyruvate, B - Oxaloacetic acid
Explanation:
The primary \(C{O_2}\) acceptor of \({C_4}\) cycle is PEP (phosphoenol pyruvate) which undergoes carboxylation to foem the first stable product OAA (oxaloacetic acid).
