Explain how protein pumps are able to move small molecules and ions across a cell membrane
What are the upsides/benefits given to a cell from the phospholipid bilayer
Homework Answers
Small molecules which are of hydrophilic nature can not transfer easily because they are blocked by the hydrophobic core of the cell membrane so that with the help of protein pump they easily transfer passively but large molecule are require energy so transfer actively. Phospholipid bilayer gives that benefit to the cell by selectively permeability,by the selection of the substance which is required by the cell to continue the process
