Step 1: Understand what enzymes are - Enzymes are proteins that help speed up chemical reactions in the body.
Step 2: Learn about temperature - Enzymes work best at certain temperatures. If it's too hot or too cold, they may not work well.
Step 3: Know about pH - pH is a measure of how acidic or basic something is. Enzymes also have a preferred pH level. If the pH is too high or too low, enzyme activity can decrease.
Step 4: Recognize substrate concentration - Substrates are the molecules that enzymes act on. If there are too few substrates, the enzyme can't work efficiently. If there are too many, the enzyme can become saturated and also not work as well.
