Question

do you think that passive transport would require energy for transport?
yes, because this type of transport uses a membrane protein.
no, because even though a membrane protein is needed, the molecules are still moving down their concentration gradient.
rewatch

Explanation:

Passive transport moves substances down their concentration gradient without the use of energy. While some forms may involve membrane - proteins, the driving force is the concentration difference, not energy input.

Answer:

No, because even though a membrane protein is needed, the molecules are still moving down their concentration gradient.
