enzymes function most efficiently are the temperature of typical cell, which is 37 Celsius increases or decreases in temperature
Veronika [31]

The information given about enzymes suggests that the enzymes have the capability to change their size at higher temperatures which affect their activity.

<h3>What are Enzymes?</h3>

Enzymes may be defined as biocatalysts that perform the important function of increasing the rate of a chemical reaction without being consumed in the process. It may be thought that all cellular reactions and processes are mediated by enzymes.

Temperature is a physical property that can significantly affect the activity of enzymes. It results in the denaturation of enzymes, irreversibly altering their structure. Enzymes perform their most suitable activity at the temperature of 37°C.

Therefore, the information given about enzymes suggests that the enzymes have the capability to change their size at higher temperatures which affect their activity.
