In a highly high-temperature environment, you placed an enzyme and some substrates. You've seen that there hasn't been any reaction. Applying what you have learned on enzyme activity, how would you explain what occurred? A. The enzyme was not placed at a pH level that would allow it to react at its maximum rate. B. There are not enough enzymes for the reaction to occur. C. The enzyme may have denatured or broken down due to the high temperature of the environment, resulting in no reaction. D. There are not enough substrates for reaction to occur. Substrate concentration affects enzyme activity. Determine what would occur when there are too many substrates and fewer enzymes? A.
