The light-mediated increase of pH and the concentration of Mg2+ activate enzymes of the Calvin–Benson cycle that require Mg2+ for catalysis and are more active at pH 8 than at pH 7: rubisco, fructose 1,6-bisphosphatase, sedoheptulose 1,7-bisphosphatase, and phosphoribulokinase.  The modifications of ionic composition of the chloroplast stroma are reversed rapidly upon darkening.

#Unit 3. Fundamental Processes

The charging of a tRNA with its cognate amino acid is a remarkably accurate process.

Experimental measurements indicate, for example, that at equal concentrations of isoleucine and valine, IleRS transfers ∼40,000 isoleucines to tRNAIle for every valine it so transfers.
