Answer:

The correct answer is option B. "It is unchanged and can be used again for the same chemical reaction".

Explanation:

One characteristic of enzymes is that they are reusable. Enzymes are not reactants and are not used in the reaction that they catalyze. Once the enzyme catalyzes a chemical reaction, it remains unchanged and can be used again for the same chemical reaction. Usually, one enzyme can bind onto several substrate molecules and catalyze the same reaction multiple times.

What is the mass of an atom with seven neutrons and eight electrons
Mrrafil [7]

Answer:

15 AMU, or 15 daltons.

Explanation:

Typically the number of protons matches that of the electrons. So, there's 8 protons and 7 neutrons. The 8 electrons have a total mass of 8/1000 AMU, not significant enough to be counted. So the total mass is 15 AMU.
