Which of these molecules is correctly matched with its method of movement through the plasma membrane?

A) Lipid-soluble molecules - pass through membrane channels
B) Small, water-soluble molecules (ions) - dissolve in double phospholipid layer
C) Large, water-soluble molecules - transported by carrier-mediated processes
D) Glucose and amino acid molecules - pass through membrane channels
E) All of the choices are correctly paired.

Carrier-Mediated Processes

Biological transport mechanisms in which specific carrier proteins facilitate the movement of molecules across cell membranes.

Lipid-Soluble Molecules

Molecules that can easily cross cell membranes due to their solubility in lipids, affecting the transport and signaling within cells.

Plasma Membrane

A bilayer of lipids and proteins that forms the external boundary of the cytoplasm of a cell, regulating the passage of molecules in and out of the cell.

  • Understand the fundamental concepts of membrane transport mechanisms, encompassing both mediated and active transport processes.
