If your body lacks enzymes that break down carbohydrates, it would be unable to get sugar molecules for energy production. If you lacked the enzyme to digest proteins, you may not absorb enough amino acids?
Answer:It is this coupling of chemistry and movement that gives proteins the ... to place the protein in a particular location in the cell—an example is the SH2 ... At one level, the cell controls how many molecules of each enzyme it makes ... One of the best understood pump proteins is the calcium transport protein from muscle cells.
