Question

If the movement of substances is from low concentration to higher

concentration: *
1 point
it would not require energy
it would still be passive transport
it would require ATP, a form of energy
none of the above

Answer 1

It would require ATP, a form of energy

Step-by-step explanation:

If the substance is moving from low concentration to high concentration, it would be going against the gradient. For example, if you were riding your bike down the hill (high to low), you would be able to coast down. However, if you were riding your bike up the hill (low to high), you would need to put in energy to pedal up. Hope this helps!
