The significance of the given observation in regards to CO 2 assimilation process and the way in which light dependent reactions of photosynthesis are related. Introduction: The photosynthesis is a process in which the green plants and algae obtain their nutrients by using solar energy, carbon dioxide, and water. This process takes place in chloroplast where the chlorophyll molecules are present. The chloroplast contains thylakoid molecules where light reaction takes place. The end product of the light reaction is formation of ATP and NADPH. These energy storing molecules together help in driving the Calvin cycle in stroma of chloroplast.

The beta-lactamase hydrolyzes the lactam-ring in penicillin. Describe the mechanism of hydrolysis, insuring to include the involvement of S, D, & K in the reaction sequence. Please help

To map the active site of beta-lactamase, the enzyme was hydrolyzed with trypsin to yield a hexapeptide (P1) with the following amino acids. Glu, Lys, Leu, Phe, Met, and Ser. Treatment of P1 with phenyl isothiocyanate yielded a PTH derivative of phenylalanine and a peptide (P2). Treatment of P1 with cyanogenbromide gave an acidic tetrapeptide (P3) and a dipeptide (P4).Treatment of P2 with 1-fluoro-2,4-dinitrobenzene, followed by complete hydrolysis, yields N-2,4-dinitrophenyl-Glu. P1, P2, and P3 contain the active site serine. Why doesn't D in this hexapeptide not participate in the hydrolysis of the beta-lactam ring even though S, K, and D are involved in the catalyst?
