Aerobic respiration, or in the presence of oxygen, uses the end product of (pyruvate) in the to produce much more energy currency in the form of than can be obtained from any . Aerobic respiration is characteristic of when they have sufficient oxygen and most of it takes place in the .
Anaerobic respiration (both glycolysis and fermentation) takes place in the fluid portion of the cytoplasm whereas the bulk of the energy yield of aerobic respiration takes place in the . Anaerobic respiration leaves a lot of energy in the ethanol or lactate molecules that the cell cannot use and must excrete.
What Are Photosynthesis and Respiration? - dummies
Only plants can photosynthesize, but both plants and animals depend on respiration to release the chemical potential energy originally captured through photosynthesis.
Respiration occurs in your cells and is fueled by the oxygen you inhale. The carbon dioxide gas you exhale is the result of a completed cycle of cellular respiration.
Cellular Respiration Overview ( ATP ) - HyperPhysics Con…
Cellular respiration produces CO2 as a metabolic waste. This CO2 binds with water to form carbonic acid, helping to maintain the blood's . Since too much CO2 would lower the blood's pH too much, the removal of the excess CO2 must be accomplished on an ongoing basis.
The first step in in all living cells is , which can take place without the presence of molecular oxygen. If oxygen is present in the cell, then the cell can subsequently take advantage of via the to produce much more usable energy in the form of than any anaerobic pathway. Nevertheless, the anaerobic pathways are important and are the sole source of ATP for many anaerobic bacteria. Eukaryotic cells also resort to anaerobic pathways if their oxygen supply is low. For example, when muscle cells are working very hard and exhaust their oxygen supply, they utilize the anaerobic pathway to lactic acid to continue to provide ATP for cell function.

The term cellular respiration refers to the biochemical pathway by which cells release energy from the chemical bonds of food molecules and provide that energy for the essential processes of life. All living cells must carry out cellular respiration. It can be in the presence of oxygen or . carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells. More emphasis here will be placed on where the are the site of most of the reactions. The energy currency of these cells is , and one way to view the outcome of cellular respiration is as a production process for ATP.

Glycolysis itself yields two ATP molecules, so it is the first step of anaerobic respiration. , the product of glycolysis, can be used in to produce ethanol and + or for the production of lactate and NAD+. The production of NAD+ is crucial because glycolysis requires it and would cease when its supply was exhausted, resulting in cell death. A general sketch of the anaerobic steps is shown below. It follows Karp's organization.

is the chemical process by which green plants convert sunlight into sugar. In essence, this process transforms a wave of light energy into chemical potential energy, which the plant then stores in the molecular bonds of sugar molecules.

The plant uses the stored chemical energy of ATP to make glucose from carbon dioxide. The plant then uses the glucose to make even larger compounds of cellulose and starch, which store energy.

Roles of ATP
ATP is an immediate energy source due to the instability of the phosphate bonds
ATP is the source of energy for:
- ATP provides the energy for muscle contraction, it provides the energy for the filaments of the muscle to slide past one another and shorten the overall length of the muscle fibre
- ATP molecules fix to myosin heads which cause them to detach from the actin filament at the end of one 'row' movement
ATP provides the energy needed to build up macromolecules from their basic units:
- Polysaccharide synthesis from monosaccharides
- Polypeptide synthesis from amino acids
- DNA/RNA synthesis from nucleotides
- ATP Provides the erngy to change the shape of carrier proteins in plasma membranes.
