A) Ribozyme
B) Rubisco
C) Pepsin
D) Yeast extract
Correct Answer: B
Solution :
Rubisco (ribulose 1, 5-biphosphate carboxylase oxygenase enzyme) catalyses the carboxy- lation step of Calvin cycle of photosynthesis, in the incorportion of a molecule of \[C{{O}_{2}}\] with a molecule of ribulose bisphosphate, forming 2 molecules of phosphoglycerate. It is the most abundant protein of all natural proteins. Ribozyme is any RNA molecule that can catalyse change to its own molecular structure, eg, self-splicing of introns. Pepsin is an enzyme that catalyses the breakdown of proteins to polypeptides in the vertebrate stomach. It is secreated as an inactive precursor, pepsinogen.
