Question

which of the following is the most direct source of energy for symport transport? multiple choice the movement of one of the transported substances up its concentration gradient symport requires no energy the movement of one of the transported substances down its concentration gradient atp hydrolysis atp formation

Explanation:

Symport is a type of secondary - active transport. It uses the energy from the movement of one substance down its concentration gradient to move another substance up its concentration gradient. ATP hydrolysis is not the most direct energy source for symport. Symport does require energy.

Answer:

The movement of one of the transported substances down its concentration gradient
