Which of the following best describes what happens to an enzyme after it catalyzes a chemical reaction?
Pachacha [2.7K]

Answer:

<em>The correct option is B. It is unchanged and can be used for the same chemical reaction.</em>

Explanation:

Enzymes can be described as proteins which act as biological catalysts. Enzymes can speed up a reaction. During this process, the enzyme itself doesn't get consumed and hence, it can be reused. Enzymes are specific for a particular type of substrate and hence, they can catalyze only those reactions for which they are specific. Hence, option B is correct.

Other options like option A is not correct because the mass of an enzyme will not change after a reaction.

Which of the following is not responsible for driving deep ocean circulation?
Deffense [45]

Answer:

Winds

Explanation:

Winds only act on oceans surfaces. The winds move the upper layers of ocean waters due to drag as they blow in the atmosphere. They are the reason for waves. However, the effects of winds cannot be felt in deep oceans where much of the movement is dependent on variable densities of ocean currents (due to differences in temperatures and salinity levels).
