Answer:
Enzymes may require a nonprotein cofactor or ion for catalysis to take speed up more appreciably than if the enzymes act alone;
Enzymes increase the rate of chemical reaction by lowering activation energy barriers.
Explanation:
Some enzymes need a cofactor to act, it is attached to the enzyme and can be nonprotein such as a metal ion. The enzyme function depends on the physical properties of the environmental, especially temperature and pH, each enzyme has a great point of pH and temperature where it has a maximum activity.
If the three-dimensional function of an enzyme is altered, it loses it specified and may not catalyze the reaction, because the structure of the enzyme is responsable for its specified. The catalyst occurs because the enzyme lows the activation energy barriers and this increases the rate of the reaction.

<h2>Answer:</h2>
Compound. Option A is correct
<h2>Explanations:</h2>
When two or more different elements combines, a compound is formed. For instance, if carbon and oxygen combines, carbondioxide is formed according to the equation;
From the reaction, carbon and oxygen are the elements while carbondioxide is the compound. Hence we can conclude that a pure substance formed when two or more different elements combine called compound.
