Answer:
•What is RuBisco and what does it do?
~RuBisCO, is an enzyme that catalyses the first major step of carbon fixation, a process by which atmospheric carbon dioxide and water are converted to energy-rich molecules such as glucose, using sunlight. In green parts of plants, the protein RuBisCO can make up to 50 per cent of the total amount of the protein fraction. Thereby, RuBisCO is the key photosynthetic enzyme in green leaves of plants and is considered the most abundant protein present on earth.
