Learn how enzymes work to sustain life.

Enzymes

The biological importance of enzymes becomes apparent as this program vividly reveals how enzymes work to sustain life. Two dimensional models are animated and used to illustrate enzyme activity and the factors affecting enzyme activity. The narration provides a concise and step-by-step approach to learning about enzymes to ensure student comprehension.
