Final answer:

Enzymes are impacted by temperature, and the statement is false. High temperatures can denature enzymes, altering their structure and effectiveness, while very low temperatures can reduce enzyme activity.

Step-by-step explanation:

The statement that enzymes are not impacted by temperature is false. Enzymes, being proteins, have a specific three-dimensional structure that is crucial for their function. This structure can be affected by changes in temperature, particularly at high temperatures through a process known as denaturing. Denatured enzymes lose their three-dimensional structure and, consequently, their functionality. Optimum temperatures for enzyme activity are generally close to the body temperature of the organism from which they are derived, often between 37°C and 40°C for human enzymes. Above optimal temperatures, enzymes become less effective and eventually denature. Similarly, very low temperatures, such as 0°C, can significantly reduce enzyme activity, although this is typically reversible upon warming.
