Answer: Option C.
Enzymes lowers activation energy required for a given reaction.
Explanation:
Enzymes are biological catalysts that are produced by living organisms which speed up the rate of chemical reaction.
Enzymes lower the activation energy of a given reactions. As the activation energy is lowered, the reaction becomes faster. Enzymes speed up the rate of reaction by lowering the activation energy.
Answer:
<u>B. Lithium, because it has two energy levels with one electron in the second level.</u>
Answer:
Cancer cells are characterized by mutations associated with the uncontrolled growth of these tumor cells
