Substances can enter and exit the cell through the membrane through passive or active transport. The processes of endocytosis and exocytosis ensure, respectively, the entry and exit of macromolecules and other particles.

<h3>In which two ways do substances cross the membrane?</h3>

The selective passage of substances across the membrane occurs in two different ways:

  • active transport, when it involves the use of energy.
  • passive transport, when it does not involve the use of ATP.

With this information, we can conclude that substances can enter and exit the cell through the membrane through passive or active transport. The processes of endocytosis and exocytosis ensure, respectively, the entry and exit of macromolecules and other particles.
