Question

Hatch and Slack pathway is otherwise known as $C_4$ cycle because:

• A. The first stable product is oxaloacetic acid/OAA which is a $C_4$ – compound
• B. The primary $C{O}_2$ acceptor is OAA, a $C4$ compound
• C. All intermediate metabolites are $C_4$–compounds
• D. At one time $4C{O}_2$ molecules take part in carboxylation pathway

Answer 1

The correct option is A The first stable product is oxaloacetic acid/OAA which is a $C_4$ – compound

The Hatch and Slack pathway is also known as $C_4$ pathway because first stable product of this pathway is 4-C carbon compound OAA (oxaloacetic acid).
