Answer:
The mechanism that requires the direct hydrolysis of ATP at the time of transport is called Active Transport. Active transport is the movement of molecules across the cell membrane against the concentration gradient. It requires energy, which is supplied by ATP hydrolysis. This mechanism is essential for bacterial cells to take up nutrients, such as sugars and amino acids, from their surroundings when the concentration of these molecules is lower outside the cell than inside.
