How is `CO_(2)` fixed in photosynthesis in `C_(4)` plants? Explain.

1.	How is `CO_(2)` fixed in photosynthesis in `C_(4)` plants? Explain.
Answer» `C_(4)` plants initially fix atmospheric `CO_(2)` to yield a `C_(4)` acid `(C_(4)` cycle). This is called first carboxylation in which phosphoenol pyruvic acid is carboxylated to `C_(4)` acid which subsequently donates one carbon as `CO_(2)` to the calvin cycle (`C_(3)` cycle) where second carboxylation takes place.

In glycolysis, glucose splits into compounds which areA. 5-CB. 4-CC. 2-CD. 3-C
Make corrections wherever you find mistake in spellings/words in the following paragraphs :- A. When fats are used in respiration, the RQ is more than unity because fats contain more `O_(2)` and require relatively less amount of `O_(2)` for oxidation. B. The most important energy carrier is ATP. This energy rich compound is mobile and can pass from one cell into another. C. Before pyruvic acid enters Krebs cycle, one of the two carbon atoms of pyruvic acid is reduced to carbon dioxide in the reaction called reductive carboxylation. The remaining two carbon pyruvate unit is accepted by coenzyme A to form acetyl coenzyme A.
