Answer:
If a protein or molecule is taken up by the cell and must be digested it will make use of <u>lysosomes</u>.
Explanation:
Lysosomes are membrane-bound organelles that have a wide range of functions but their main 'job' is to break down large molecules into smaller molecules or to digest molecules that are present in excessive or unnecessary amounts. This is why <u>they contain important digestive enzymes known as hydrolitic enzymes.</u>
Lysosomes can break down, for example, large proteins into amino acids to provide the cell with the necessary nutrients.
Determined by its primary structure (sequence of amino acids.)
the sequence of amino acids in an protein is determined by the nucleotides in the DNA encoding it
