Question:

In Hatch and Slack pathway, the primary CO₂ acceptor is -

Options:

1. Oxaloacetic acid
2. Phosphoglyceric acid
3. Phosphoenol pyruvate
4. Rubisco

Solution:

The primary CO₂ acceptor in the Hatch and Slack (C4) pathway is Phosphoenol pyruvate (PEP), which reacts with CO₂ in the presence of PEP carboxylase to form oxaloacetate. In this pathway, oxaloacetate is converted to malate, which is then transported to bundle sheath cells. In bundle sheath cells, malate is decarboxylated to release CO₂, which is then used in the Calvin cycle. Therefore, PEP is the primary CO₂ acceptor in the Hatch and Slack pathway.
