Question

Based on the model of cellular transport, the hydrolysis of ATP and ADP provide a mechanism for

Answer 1

Answer:

Cellular transport is the movement of ions or molecules across the membrane of the cell through either active or passive process.

Explanation:

During active transport, ATP (Adenosine triphosphate) is used. In passive transport, ATP is not used. In active cellular transport, the ions move across the membrane against the concentration gradient.

For ATP to be used, it has to get hydrolyzed thereby forming ADP and inorganic phosphate. On the other hand, ADP captures the energy through the oxidation process taking place in the cell.
