Answer:
The correct answer is "uranium-238".
Explanation:
Uranium-238, is the most abundant isotope of the element uranium. Uranium-238 has not enough nuclear force to balance electrostatic forces between protons, and as a result, it is a radioactive isotope and its losing energy because of the spontaneous breakdown of its atomic nucleus. Uranium-238 has a half-life of 4.5 billion years and is used as fuel in nuclear reactors as well as for dating purposes.

<h3><u>Explanation:</u></h3>
Enzymes are biomolecules that act as biocatalysts and to enhance the rate of a chemical reaction. Lipids and proteins make up the cell membrane bilayer. Cholesterol is a lipid molecule that comes under the category of very low density lipoprotein. Its not associated with storing the genetic information. The DNA stores the genetic information.
Glucose is the chief respiratory substrate of a cell. Its not associated with the increase in rate of a reaction. But cellulose is the molecule that is a polymer of glucose that is associated with the formation of cell walls in plants.
