A) PEP
B) PGA
C) RuBP
D) Pyruvic acid
Correct Answer: A
Solution :
In \[{{C}_{4}}\] plants bundle sheath cells of leaf show Kranz anatomy. In \[{{C}_{4}}\] plants, the \[C{{O}_{2}}\] first accepted in the mesophyll cells by PEP (phosphoenol pyruvate) and form a four carbon compound oxaloacetic acid. Phosphoenol pyruvate \[C{{O}_{2}}\xrightarrow[Corboxylase]{PEP}\] Oxaloacetic acid In \[{{C}_{3}}\] plants, the carboxylation (addition of\[C{{O}_{2}}\]) of RuBP (Ribulose 1, 5 biphosphate) is catalyzed by an enzyme rubisco to form a 3-carbon compound phosphoglyceric acid (the first stable product of \[{{C}_{3}}\] plants). RuBP \[+C{{O}_{2}}\xrightarrow{Rubisco}\] 3-phosphoglyceric acid Pyruvic acid is the end product of glycolysis During glycolysis one molecule of glucose is breakdown into two molecules of pyruvic acid.
