Which factor is most likely to increase the rate of an enzyme reaction? A) Increasing the concentration of substrate B) Doubling the concentration of product C) Lowering the temperature dramatically D) Increasing the pH to extreme levels
Understand the Problem
The question is asking about the factors that can influence the rate of an enzyme reaction. It presents multiple choice options, suggesting that we need to identify which option would most likely enhance the enzyme's activity.
Answer
Increasing the concentration of substrate.
The final answer is Increasing the concentration of substrate.
Answer for screen readers
The final answer is Increasing the concentration of substrate.
More Information
The rate of enzyme reactions typically increases with higher substrate concentrations because more substrate molecules interact with enzyme sites up to a certain point, known as saturation, beyond which increases no longer enhance the rate.
Tips
A common mistake is thinking that substrate concentration always increases rate linearly; however, it eventually levels off when the enzyme becomes saturated.
