Introduction:
The ability to do work is called energy. There are two types of energy, i.e. kinetic energy and potential energy. The energy which is in the stored form is called potential energy. Example of potential energy is drawing a bow, stretching of a rubber band. In the same way cell also required energy to do the work. Potential energy is stored in the bonds, which connects the atoms in molecules.

Answer to Problem 1MCQ
Correct answer:
The best example of potential energy in the cell is a molecule of glucose. Therefore, the option b. is correct.
Explanation of Solution
Reason for the correct statement:
A molecule of glucose can undergo both the glycolysis and the citric acid cycle pathway. It releases an ATP molecule in both the pathways using the electron transport chain. When the glucose molecule is broken down, they release energy. They are not an energy molecule, but can be broken down to from energy molecule ATP.
Option b. is given as potential energy in a cell is “A molecule of glucose”.
As, “the molecules of glucose break down and generates energy”, is the correct answer.
Hence, option b. is correct.
Reasons for the incorrect statements:
Option a. is given as “Cell division”.
Cell division is a process by which a parent cell divides into two daughter cells. The energy is exhausted during cell division. So, it is a wrong answer.
Option c. is given as “movement of a flagellum”.
The flagella are the motile structures that offer movement to cell. The flagella are the best example of kinetic energy. So, it is a wrong answer.
Option d. is given as “assembly of a cellulose fiber”.
The cellulose is a polysaccharide whose monomer is glucose. Here the cellulose fibers provide the structural framework to the cells. The energy stored in the cellulose cannot be utilized in the terms of energy. So, it is a wrong answer.
Hence, option a., c., and d. are incorrect.
Glucose is not an energy molecule, but can generate ATP, which is known as the powerhouse of the cell. It can be broken down to release energy. So glucose is an example of potential energy.
