Membrane transport involves the migration of micro as well as macromolecules throughout the membrane. The transport of micromolecules involves H+ ion, Na+ ion, oxygen, and glucose while the transport of macromolecules involves proteins, lipids, pathogens, etc.
What do you mean by Membrane transport?
Membrane transport may be defined as the gesture of particles such as solutes across or via a membranous barrier that is made up of a lipid bilayer.
Micromolecules undergo active and passive transport with different mechanisms. Active transport requires carrier proteins where energy is needed in form of ATP. Passive transport undergoes simple and facilitated diffusion.
Macromolecules undergo exocytosis and endocytosis. Exocytosis may be constitutive and regulative while endocytosis involves phagocytosis, pinocytosis, and receptor-mediated endocytosis.
Therefore, it is well described above.
