The endocrine system produces hormones that regulate metabolism, growth and development, tissue function, sexual reproduction, sleep, and mood. The reaction is called aerobic respiration because oxygen from the air is needed for it to work. Photosynthesis is defined as the process, utilized by green plants and photosynthetic bacteria, where electromagnetic radiation is converted into chemical energy and uses light energy to convert carbon dioxide and water into carbohydrates and oxygen. The respiratory system includes airways, lungs and respiratory muscles. The oxygen gets in the body through the respiration process. Oxygen forms a large part of the air on earth, and is needed by animals and plants to live. Oxygen is the chemical element with the symbol O and atomic number 8. Synonym(s): oxygen uptake . Oxygen (98.5%) is transported by hemoglobin as Oxyhaemoglobin (Hb-O2) within Red Blood Cells. The oxygen cycle is a biological process which helps in maintaining the oxygen level by moving through three main spheres of the earth which are: CallUrl('myplace>frontier>com<~dffixhtm',0), Aerobic Respiration: The process of breaking down Glucose in the presence of ~TildeLink() to create ATP.Anaerobic Respiration: The process of breaking down Glucose in the absence of ~TildeLink() to create ATP.
