Enzyme activity can also be charted through the __________ ?
Correct answer: B. Rate of reaction
- A. Rate of digestion
- B. Rate of reaction
- C. Level of pH
- D. Number of active sites
Explanation
Enzyme activity is measured by how quickly substrate is converted into product, which is expressed as the rate of reaction. Students may choose c because pH affects enzyme activity, but pH is a factor being tested, not the direct measure of activity.

About Characteristics of Enzymes
Enzymes are globular biological catalysts that lower activation energy without being consumed, usually showing specificity for particular substrates. Questions cover active sites, enzyme substrate complexes, the lock and key and induced fit models, intracellular and extracellular action, and the effects of denaturation, while distinguishing enzymes from non biological catalysts.
