Protein denaturation: Surface denaturation in bovine albumin solutions is to protein measurement as ___ is to enzyme activity.

Surface denaturation in bovine albumin solutions lets us estimate protein concentration by measuring the turbidity that appears when proteins unfold on a surface. In enzyme work the parallel is the rate of substrate turnover, which tells us how fast the enzyme converts substrate to product. Both methods rely on a measurable change that is directly proportional to the amount of protein or enzyme present. Thus, surface denaturation is to protein measurement what substrate turnover is to enzyme activity.
