Solved in 2 steps
- Melvin Calvin and Andrew Benson determined the steps in the light-independent reactions of photosynthesis by exposing the green alga Chlorella to CO2 labeled with the radioisotope carbon 14. By looking at which compounds the C14 ended up in, they were able to identify all intermediates in this cyclic pathway. Why did they predict correctly that the same set of intermediates would be formed in the light reaction in land plants?Enlist and explain the agents that effects Phosphorylation or PhotophophorylationSuggest a reason why plants contain lightabsorbing pigments in addition to chlorophylls a and b.
