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

Respuesta :

Answer:

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.

The statement which is correctly matches with the source of energy is the covalent bonds of a sugar molecule: potential energy.

What is energy?

Energy is the capacity of a object to do a work. More the energy object posses, more the work it can do.

The main categories of Learn more about the energy here;

  • 1. Kinetic—The energy of moving objects.
  • 2. Potential—The energy stored in objects.

Let's check all the option one by one.

  • a) The heat released from a living organism is chemical energy.
  • b) The energy related to the height of a bird above the ground has the potential energy due to its height.
  • c) The covalent bonds of a sugar molecule is a form of potential energy, as the energy arises from the respective locations of the atom, which forms the bond.
  • d) The motion of individual molecules is the form of kinetic energy.
  • e) The energy associated with a gradient of ions across a membrane is potential energy, as this is a type of stored energy which helps to move other molecules.

Hence, the statement which is correctly matches with the source of energy is the covalent bonds of a sugar molecule: potential energy.
