Hint: The most abundant protein in nature is the chloroplast enzyme and the protein found in the bones, muscles, skin, and tendons. It is arguably the most important enzyme because it catalyses the carbon dioxide-fixing step in photosynthesis.
Complete answer:
RuBisCO is very important in biology and ecology because it catalyzes the primary chemical reaction by which inorganic carbon permanently gets into the biosphere. RuBisCO is also the most abundant protein in leaves and the most abundant protein on the Earth. Collagen is the most abundant protein (structural protein) in the animal world and is the structural component of most animals.
Additional Information:
Lack of collagen:
As a person ages, their body starts to produce less collagen. This lack of collagen results in the common signs of ageing. Wrinkles, sagging skin that has lost its elasticity, and stiff joints are all the signs that the body is producing less collagen. When collagen levels are greater in the body, the skin is soft, smooth, and firm.
Lack of RuBiSco:
RuBisCO is responsible for fixing carbon in the form of carbon dioxide into ultimately what becomes complex sugars. So without RuBisCO, plants would have no long term means of storing the energy of the sun.
So, the correct answer is, 'Collagen is the most abundant protein in the whole of the biosphere and RuBisCo is the most abundant protein in the animal world.'
Note: Role of RuBiSco and Collagen:
-The enzyme ribulose 1,5-bisphosphate carboxylase (Rubisco) catalyses the entry of carbon dioxide into photosynthetic metabolism, provides acceptor molecules that consume the products of the light reactions of photosynthesis, and regulates the pool sizes of important photosynthetic intermediates.
-Collagen is the protein in the human body, which is the most abundant one. It is the major component of connective tissues that make up several body parts, including the bones, tendons, ligaments, skin, and muscles. Collagen has many important functions, including providing the skin with structure and strengthening of the bones.
