Verified by Toppr

Collagen is a fibrous protein. It is the most abundant protein in the whole of the biosphere. It provides structural support to the cell. These are filamentous and elongated in shape. They are generally water soluble in shape. It has a quaternary structure. It is a multiple folded protein.
RuBisCO is the most abundant enzyme which is used to fix carbon during dark reaction of the photosynthesis. It is a primary acceptor of carbon dioxide during Calvin cycle. It is also known as Ribulose-1,5-bisphosphate carboxylase/oxygenase. It fixes the carbon dioxide to 3-phosphoglycerate. It also accepts oxygen during photorespiration and forms phosphoglycolate and 3-phosphoglycerate.
So, the correct answer is option A.
