Investigation: Enzyme and Substrate Concentrations

NettetCells make the enzyme catalase to remove hydrogen peroxide. This investigation looks at the rate of oxygen production by the catalase in pureed potato as the concentration of hydrogen peroxide varies. The oxygen produced in 30 seconds is collected over water. Then the rate of reaction is calculated. NettetEnzyme activity is measured in units which indicate the rate of reaction catalysed by that enzyme expressed as micromoles of substrate transformed (or product formed) per minute. An enzyme unit is the amount of enzyme that will catalyse the transformation of 1 μmol of substrate/min under specified conditions of pH and temperature.

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.
