Definitions:

Facilitated Diffusion

A transport mechanism for molecules across the cell membrane via protein channels, without energy expenditure.

Energy Expenditure

The total amount of energy used by the body per day, encompassing basal metabolic rate, physical activity, and the energy used in digesting and metabolizing food.

Plasma Membrane

The semipermeable membrane surrounding the cytoplasm of a cell, responsible for controlling the passage of substances in and out.

Bilayer

A bilayer typically refers to a double layer of closely packed atoms or molecules, the most common example being the lipid bilayer of cell membranes that forms the cell's outer boundary.
