The plasma membrane consists of proteins that allow transport of molecules. These transport mechanisms are either passive or active in nature, which depends on the energy. Active transport mechanisms require energy for transport of molecules as they move molecules against a concentration gradient. Diffusion is simply the movement of molecules from a region of higher concentration to a region of lower concentration.

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.
