337365 Read the following statements carefully and select the number of correct statements.
(a) RuBisCO is the most abundant enzyme in the world.
(b) RuBisCO has a much greater affinity for \({O_2}\) when the \(C{O_2}\): \({O_2}\) is nearly equal.
(c) The binding \(C{O_2}\) and \({O_2}\) with RuBisCO is symbiotic.
(d) It is the relative concentration of \({O_2}\) and \(C{O_2}\) that determines which of the two will bind to the RuBisCO.
