ENZYMES

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If you are testing for the effect of enzyme concentration on rate of reaction, what IS NOT a constant variable?
A
type of enzyme
B
enzyme concentration
C
concentration of substrate
D
Type of substrate
Explanation: 

Detailed explanation-1: -Enzyme concentration: Increasing enzyme concentration will speed up the reaction, as long as there is substrate available to bind to. Once all of the substrate is bound, the reaction will no longer speed up, since there will be nothing for additional enzymes to bind to.

Detailed explanation-2: -The dependent variable is the rate of the reaction. The independent variable is the concentration of enzyme, the concentration of the substrate, the temperature, and the addition of an inhibitor. Introduction: Enzymes are proteins that carry out chemical reactions.

Detailed explanation-3: -Several factors affect the rate at which enzymatic reactions proceed-temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.

Detailed explanation-4: -Enzymes typically increase the rate of reaction by decreasing the activation energy and this implies that enzymes increase the rate constant.
