All living organisms partake in some form of cellular respiration. This includes bacteria, fungi, protists, plants and animals. Cellular respiration is sometimes called aerobic respiration because it requires oxygen to occur, although a few organisms are capable of anaerobic respiration, respiration without oxygen.Continue Reading
All life-forms require energy to move, grow, repair damage and reproduce. Many organisms, such as plants and algae, are able to produce their own energy from sunlight. These photosynthesizing organisms form the base of their respective food chains, and all subsequent organisms in these food chains obtain their energy by consuming this photosynthesizing life or consuming other organisms that rely on photosynthesizing life.
The chemical energy that all organisms acquire through photosynthesis or consumption provide the cells with nutrients, such as complex and simple sugars, fats and amino acids. These nutrients are broken down in the cellular respiration process in the presence of oxygen. The final product of the cellular respiration process is an energy-rich molecule called ATP. This ATP is the simplest form of energy used by all life.
Anaerobic life-forms use other oxidizing agents besides oxygen to break down complex nutrients into simpler ones. These oxidizing agents include sulfates and nitrates, but they are not as efficient at oxidization as oxygen.Learn more about Biology
The presence of oxygen, nutrients and space to discard their metabolic products are the conditions for cellular respiration in aerobic organisms. Anaerobic organisms require an absence of oxygen and the presence of different nutrients from their aerobic counterparts.Full Answer >
Cutaneous respiration occurs in insects and organisms that do not have respiratory organs. These organisms diffuse dissolved oxygen across their bodies in order to breathe.Full Answer >
Many organisms perform cellular respiration, including animals, bacteria, fungi and protozoa, according to CliffsNotes. These organisms use carbohydrates derived from plants to acquire the energy they need to carry out metabolic processes.Full Answer >
According to the BBC, aerobic respiration requires oxygen in order to release energy from glucose for cellular use. Carbon dioxide and water are waste products of aerobic respiration. This process occurs in organelles called mitochondria, which are the energy producing parts of the cell.Full Answer >
