Cell Transport Mechanisms Quiz

What is the primary function of bulk transport in cells?

• To facilitate the movement of water molecules

• To import or export large molecules across the plasma membrane

• To transport small ions across the cell membrane

• To generate energy for the cell

Which process involves the secretion of substances from the cell?

• Exocytosis

• Phagocytosis

• Endocytosis

• Pinocytosis

Who coined the term 'phagocytosis'?

• Louis Pasteur

• Alexander Fleming

• Robert Koch

• Ilya Mechnikov

What is the role of phagosomes in phagocytosis?

• To transport liquids into the cell

• To digest solid substances

• To secrete enzymes

• To produce energy

What is pinocytosis commonly referred to as?

• Cell breathing

• Cell vomiting

In receptor-mediated endocytosis, what binds to the receptor on the plasma membrane?

• A carbohydrate

• A lipid molecule

• A water molecule

• An extracellular macromolecule

Which process involves the intake of solid material into the cell?

• Diffusion
