If you can answer both questions I would appreciate thank you in advance

Which of the following statements is correct for the reaction catalyzed by chymotrypsin? A) The substrate carbon atom bonded to Ser195 in the acyl enzyme intermediate has a trigonal geometry B) Asp102 has a key influence on the pH-rate profile C) The oxyanion hole accelerates the reaction by tightly binding the substrate carbonyl oxygen D) Asp102 accepts a proton from His57 in the initial step, temporarily removing the negative charge on the carboxylate E) The frst reaction product released contains a proton derived from an active-site water molecule Save Question 5 (2 points) Vmax for an enzyme-catalyzed reaction A) is converted to kcat by multiplying it by the enzyme concentration B) is usually higher for substrates having lower Km values C) is limited only by the amount of substrate supplied D) is independent of the pH at which the reaction is carried out E) cannot be determined from measurements where [S]

Explanation / Answer

option C

option B Vmax is usually higher for lower Km values.But is not always true as it doesnt have any fixed patterns.
