The body prefers to use fat or carbohydrate for energy, but when total energy or carbohydrate intake is low, protein may be used instead. in order to use amino acids for energy, the amine group must first be removed. complete the statement about protein catabolism. amino acids contain nitrogen, which must be removed via oxidative in order for the carbon skeleton to be used for energy.

When in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? view available hint(s)when in solution, a molecule that moves slowly across an artificial membrane moves rapidly across a plasma membrane. this molecule rapidly enters the cell regardless of whether its concentration is higher inside or outside the cell. using this information, which transport mechanism is most likely to be responsible for the movement of the molecule across a plasma membrane? active transportexocytosis
