2, 4-7 Although deep intramuscular injection into a large muscle is the preferred parenteral route of administration, promethazineâs product labeling states that it may be given by slow IV push, which is the typical method of administration in most hospitals.
Quick Answer. Plants produce oxygen as a byproduct of photosynthesis, the process that plants and other organisms use to create usable energy. Photosynthesis consists of carbon dioxide and water reacting in the presence of energy from sunlight, which produces glucose and oxygen.
Energy is obtained more efficiently in the presence of oxygen via the process called aerobic respiration. When there is no oxygen available to break the sugar molecules, some cells are still able to produce energy by the process called fermentation or anaerobic cellular respiration or anaerobic glycolysis.Certain organisms do not need molecular oxygen to produce the energy molecules called ATP.hen there is no oxygen available to break the sugar molecules, some cells are still able to produce energy by the process called fermentation or anaerobic cellular respiration or anaerobic glycolysis.
