Introduction:
All the cellular activities require energy in one form or other. This energy can be obtained from different sources. Some energy is also stored inside the cell in the form of special

Answer to Problem 1MCQ
Correct answer:
A molecule of glucose is utilized for the production of energy currency in the cell. Hence, the correct answer is option b.
Explanation of Solution
Reason for correct answer:
Option b. is given as “A molecule of glucose.”
During the process of glycolysis, glucose molecules are converted into pyruvate. Energy molecules (ATPs) are produced during this conversion. Energy is stored as potential energy in the glucose molecules. This potential energy is the one that is transferred from the glucose molecules to ATP molecules during glycolysis. Hence, option b. is correct.
Reason for incorrect answer:
Option a. is given as, “Cell division.”
Cell division is a process that uses energy in the cell. This consumption of energy carries out some physical activities such as the movement of chromosomes, which is an example of kinetic energy and not potential energy. Hence, option a. is incorrect.
Option c. is given as, “Movement of flagellum.”
Physical movement is depicted by kinetic energy. Movement of the flagellum is a physical movement that is possible after utilizing kinetic energy. Hence, option c. is incorrect.
Option d. is given as, “exocytosis.”
Exocytosis is the process where vesicles are formed and move from the cytoplasm towards the cell membrane. This movement depicts the kinetic energy in the cell. Hence, option d. is incorrect.
Hence, the options a., c., and d. are incorrect.
A glucose molecule posses stored energy in the cell. This stored energy is a form of potential energy. Thus, the correct answer is option b.
