What Molecules require the use of carrier proteins?


Expert Answer

Step 1

Proteins are a type of biomolecules that are made up of amino acids connected via peptide bond. Carrier proteins are transport proteins present on cell membrane (encloses the components of a cell) that facilitates the transport of specific molecules across the membrane by binding to them.

Step 2

A cell membrane allows only specific molecules to pass through them which means that only molecules like water, ions and some small particle can easily pass through it without involvement of any transport protein or energy expenditure.
