All of the following are consistent with ACTIVE TRANSPORT of

All of the following are consistent with ACTIVE TRANSPORT of molecule X across a membrane EXCEPT: a. ATP Hydrolysis B. Molecule X is moving against a gradient C. Molecule X is moving from the side of higher concentration to the side of lower concentration D. The protein transporting molecule X undergoes a conformational change

Solution

Answer c: Simple diffusion invovoles movement where molecule move from higher concentration to lower concentration.. ATP is not required here.
