Energy is observed in two basic forms: potential and kinetic. Which of the following correctly matches these forms with a source of energy? See Concept 8.1
the energy associated with a gradient of ions across a membrane: kinetic energy
the motion of individual molecules: potential energy
the heat released from a living organism: potential energy
O the energy related to the height of a bird above the ground: kinetic energy
O the covalent bonds of a sugar molecule: potential energy

Answer :

Answer: potential energy

Explanation:
The correct matching of the forms of energy with their respective sources is as follows:

  • The energy associated with a gradient of ions across a membrane: potential energy
  • The motion of individual molecules: kinetic energy
  • The heat released from a living organism: kinetic energy
  • The energy related to the height of a bird above the ground: potential energy
  • The covalent bonds of a sugar molecule: potential energy

Therefore, the correct answer is:

  • The energy associated with a gradient of ions across a membrane: potential energy
