Please answer the following question: You are presented with the question "Vesicle transport requires energy and a what?" and the following answer choices: - activity - major threat to health - metabolic reaction - hydration - biofuel - wavelengths and photons - carrier molecule - Vibrations. Now knowing that vesicle transport requires energy, so it is also a form of active transport and active transport requires a carrier molecule and a form of energy, choose the best answer.
Answer:
carrier molecule
