Digestion takes place inside Iysosomes containing digestive enzymes. Hope I helped!
The answer is the second choice
The ATP enables the movement of transport proteins to move the ions across a cell membrane by its getting fueled by its hydrolysis
<u>Explanation:</u>
The plasma membrane is a semi permeable membrane that is the movement of molecules across the membrane is constricted. There are 2 types of moment across the plasma membrane one is the active transport and the other is the passive transport. The active transport involves the help of ATP whereas the passive transport does not involve ATP to transport the materials.
I don’t know if this is a question but yes a controlled experiment allows you to isolate and test the hypothesis
