Cellular respiration is performed by living cells in every variety of organism. It involves the production of an energy source within cells to be used as fuel for biological processes.Know More
A cell's energy supply is highly dependent on cellular respiration. It may be performed as aerobic or anaerobic respiration. Aerobic respiration requires the intake and combination of oxygen with water molecules to convert glucose into energy to be used by cells. Anaerobic respiration allows for the conversion of glucose into energy without the presence of oxygen. It is utilized by bacteria or when an organism has a low supply of oxygen.
Both types of respiration begin with a process known as glycolysis, which begins the breaking down and conversion of carbohydrates into usable energy. Glycolysis is performed in the cytosol of eukaryotic cells, while organelles known as mitochondria perform the remaining processes of cellular respiration. Anaerobic respiration results in the production of pyruvic acid, which is a product of glucolysis used to cause fermentation of molecules essential to energy production.
Once glycolysis is performed, the process begins the stage of converting pyruvic acid into carbon dioxide and water. This results in the production of energy molecules known as ATP, which is the final product of cellular respiration.Learn more about Biology
Cellular respiration and photosynthesis are closely related, as they are reciprocal processes. A simple summary of photosynthesis is the creation of carbohydrates through the combination of carbon dioxide and water with energy from the sun, with oxygen as a waste product. Cellular respiration is the use of oxygen to break down carbohydrates into water and carbon dioxide, releasing energy.Full Answer >
Cellular pH needs to be maintained close to seven because a slight shift in pH towards either acidity or alkalinity could result in serious harm to the organism, including death, coma, muscle spasms or convulsions. A slightly acidic pH of 6.95 or a more basic pH of 7.7 will inhibit the cell's ability to function properly.Full Answer >
Cellular respiration is the consumption of oxygen by a cell within a living organism. In plant seeds, the cellular respiration does not occur until the seed has absorbed moisture and released stored starches that can then be metabolized into energy for the purpose of growth.Full Answer >
All living cells need to perform a variety of activities, and these activities require energy. Reproduction, in particular, takes a significant amount of energy. Cells that are starved of energy sources eventually die.Full Answer >
