Oxygen and glucose are both reactants in the process of cellular respiration. The main product of cellular respiration is ATP; waste products include carbon dioxide and water. Cellular respiration refers to the metabolic reactions and processes which occur in the cells of organisms. Its products include carbon dioxide, water and energy stored as energy-rich ATP.
Epinephrine and the heart. Epinephrine binds to beta-adrenergic receptors on heart muscle cells. This causes the contraction rate of the heart to increase. This ultimately leads to increased blood supply to the tissues in the body.pinephrine, along with another hormone called glucagon, is responsible for the breakdown of glycogen in liver cells. Glycogen is a form of energy storage in animals. Epinephrine binds to a receptor on the outside of a liver cell causing a conformational change to occur. This change means that a G protein can now bind.
Adrenergic receptors respond to sympathetic stimulation and blood-borne epinephrine. Receptors are located on smooth muscle, cardiac pacemaker, myocardium and glands. Stimulatory subtypes are alpha 1 and beta 1; inhibitory subtypes are alpha 2, beta 2 &3. Adrenergic Receptors Adrenaline is the original name for what we now call epinephrine.
