試題詳解

8.How does enzyme turnover number (k＜sub＞cat＜/sub＞) relate to reaction velocity?
(A) Determines the maximum reaction velocity when the enzyme is saturated with substrate.
(B) Reflects the enzyme's catalytic efficiency relative to substrate concentration.
(C) Is directly proportional to the rate constant for enzyme-substrate binding.
(D) Indicates the fraction of substrate molecules converted to product per second.
(E) Describes the maximum catalytic rate normalized by the enzyme’s molecular weight.
