Workshop 2-BIOC 3021 Exam Questions and Answers Why does a plot of V vs S taper off and eventually reach a plateau at higher S levels? - Answers- When S levels are high, the M-M plot actually approaches a limiting value of Vmax. - At high (S), where V approximates Vmax, virtually all of the enzyme active sites are occupied by substrate. - The addition of more S would not significantly increase the rate of reaction, because the rate of reaction is limited by the total active sites availab...
