Energy is observed in two basic forms: potential and kinetic. Which of the following correctly matches these forms with a source of energy?

a. the heat released from a living organism: potential energy

b. the energy related to the height of a bird above the ground: kinetic energy

c. the covalent bonds of a sugar molecule: potential energy

d. the motion of individual molecules: potential energy

e. the energy associated with a gradient of ions across a membrane: kinetic energy

option C

Explanation:

The correct answer is option C

Kinetic energy is the energy which is due to the motion of body.

Potential energy is the energy due to virtue of position of the object.

option A is not true because potential energy is due the position of the body

Option B should be the potential energy not kinetic energy.;

Option D is motion of individual molecule leads to kinetic energy not potential energy.

So, the correct answer is option is the covalent bonds of a sugar molecule is potential energy because of the position of bond.
