Which of the following best explains the role of enzymes in a reaction c. an enzyme binds to a product causing a decrease in the rate of the reaction. a. an enzyme causes an increase in the rate of reaction by binding to a substrate. d. an enzyme increases the temperature of a reaction so that the reaction can occur faster. b. an enzyme increases the amount of energy needed to complete the reaction.

The Option A is correct i.e

By increasing the enzyme concentration, the maximum reaction rate greatly increases.

Conclusions:

The rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.

one centimetre is equal to 0.01 metres

i think that d. wind is the answer.   i missed the question when i answered a. currents.
