light energy -> chemical energy kinetic energy -> potential energy chemical energy -> mechanical energy mechanical energy -> electrical energy
I gave my students this multiple choice question: Which energy transformation occurs during active transport in a cell?

Only one answer is correct among these 4 choices:
- light energy -> chemical energy
- kinetic energy -> potential energy
- chemical energy -> mechanical energy
- mechanical energy -> electrical energy

Could you tell me which one is correct?

chemical energy -> mechanical energy
