1. Enzyme competition occurs when:
A. one type of enzyme reacts with one type of substrate.
B. an enzyme does not react with a substrate.
C. three different types of enzymes react with one type of substrate.
D. an enzyme stops a reaction.
is it C
2. The proton pump is responsible for the production of:
A. ATPs.
B. oxygen.
C. ADP.
D. All of these answers are true.
is it D
To find the answer to the first question, we need to understand what enzyme competition means. Enzyme competition occurs when multiple enzymes compete for the same substrate molecule. By analyzing the answer choices, we can eliminate options A, B, and D as they do not describe this scenario. Option C, stating that three different types of enzymes react with one type of substrate, indicates enzyme competition. Therefore, the answer to the first question is indeed option C.
For the second question, we need to determine the main output of the proton pump. The proton pump is responsible for pumping protons across a membrane, generating a concentration gradient. This gradient is used to produce ATP, which is the energy currency of the cell. So, the correct answer is option A, ATP production. Options B and C are incorrect as they do not accurately describe the function of the proton pump. Therefore, the answer to the second question is A.
