Control of physiological activities. Homeostasis involves the steady state and regulation of the body's internal environment. Irritability is the ability to respond to a stimulus.

Answer and explanation;

-ATP plays an important role in muscle contraction without which the muscles would become rigid and are unable to move.

-Cellular respiration is the process by which cells make ATP by breaking down organic compounds from food such as glucose. Cellular respiration is divided into; anaerobic respiration which does not involve use of oxygen and aerobic respiration occurs in presence of oxygen.

-Muscle cells are able to produce ATP with oxygen ( aerobic respiration), or without oxygen (anaerobic process called anaerobic glycolysis or fermentation). The two process are instrumental to enhance muscle contractions by ensuring continuous generation of ATP.
