<reasoning>

Analyze Question 21

The question asks for the term used to describe an enzyme whose shape has been permanently changed due to high temperature or extreme pH. When an enzyme's tertiary structure is disrupted, losing its functional shape, it is referred to as denatured.

Analyze Question 22

The question asks what regulates most cellular activities. Enzymes are biological catalysts that speed up and regulate metabolic reactions and cellular processes.
