thermal energy to kinetic energy potential energy to light energy chemical energy to kinetic energy kinetic energy to potential energy
I gave my students this multiple choice question: Some plant cells need energy to carry nutrients across the cell membrane. Which type of energy transformation does these plant cells use to bring the nutrient molecule inside the cell membrane?

Only one answer is correct among these 4 choices:
- thermal energy to kinetic energy
- potential energy to light energy
- chemical energy to kinetic energy
- kinetic energy to potential energy

Could you tell me which one is correct?

chemical energy to kinetic energy
