WebTypical enzymes can process a thousand molecules per second, but rubisco fixes only about three carbon dioxide molecules per second. Plant cells compensate for this slow rate by building lots of the enzyme. Chloroplasts are filled with rubisco, which comprises half of the protein. This makes rubisco the most plentiful single enzyme on the Earth. Web15 okt. 2024 · C4 plants, on the other hand, are well known to perform better than C3 plants. C4 plants consume less water per unit of carbon fixed than plants with other forms of carbon, resulting in increased water conservation in hot, dry climates. Furthermore, by being less energetically wasteful in the light response, C4 plants mitigate the problem of ...
