A student carried out an investigation into the effect of temperature on the rate of an enzyme-catalysed reaction.

At each temperature, the substrate concentration was measured after 10 minutes. All the other

variables were kept constant.

Which graph shows the effect of increasing temperature on the substrate concentration after

10 minutes?

Pls explain

First graph.

Explanation:

If further increase in temperature occurs, it leads to decrease the substrate concentration because with very high temperature the enzyme is unable to perform its function. If the temperature is in optimum range, the enzyme produces more substrate due to favorable environment while on the other hand, if the temperature is below or above the optimum range so the enzyme can't perform its function properly and the substrate produce in small concentration.
