the movement of molecules down a concentration gradient is a form of:
active transport
potential energy
stored chemical energy
kinetic energy
solar energy

Explanation:

• Active transport requires energy (usually ATP) and moves molecules against a concentration gradient.
• Potential energy is stored energy.
• Stored chemical energy is energy within chemical bonds.
• Kinetic energy is the energy of motion. Molecular movement down a concentration gradient is a form of kinetic energy as it involves the motion of molecules.
• Solar energy is energy from the sun.

Answer:

kinetic energy
