Question

Describe the relationship between ATP and protein pumps and their role in moving large particles across a cell membrane.

Answer 1

Protein pumps use ATP to move molecules or ions into the cell membrane. Most of the time they are working against the concentration gradient meaning large molecules like sugars have to be pumped from areas of lower concentration to high concentration. This requires the use of ATP. Therefore, there is a direct relation between ATP and Protein pumps because the more ATP being used means the more molecules or ions are being pumped.

Answer 2

The plasma membrane is the selectively permeable membrane that helps in the transportation of molecules. Two main types of the transport are active transport and passive transport.

The protein pumps are used for the transportation of selected molecules against the concentration gradient. The ATP molecule is used for the transportation of molecules by the protein pumps. The large molecules and ions are transported across the membrane by the use of ATP molecules through the protein pump.
