How substrate affects enzyme activity
Nettet15. mar. 2024 · Enzyme concentration. The higher the enzyme concentration, the more enzymes there are to form enzyme-substrate complexes, leading to an increase in enzyme activity. This happens up to a certain point. NettetThe rate of enzyme activity increased along with the surface area of substrate. As particle size decreased, the surface area increased. Hence in the experiment, the large lumps of potato pieces were involved in a much slower reaction compared to the mashed potatoes which had produced a larger amount of foam in one minute.
