Respiration Flashcards
What is Respiration?
a process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
Where does Respiration take place?
mitochondria
Cellular repiration takes place in the mitochodrion. The 3 phases of cellular respiration are Glycolysis (Fermentation), Krebs Cycle, and Electron Transport. Glycolysis takes place in the cytoplasm. The Krebs cycle and electron transport takes place in the mitochondria.
Why is Respiration important?
So, cellular respiration is important because it provides the energy for living organisms to perform all of the other necessary functions to maintain life. Most single-celled organisms, such as bacteria, do not require much energy and are able to survive on glycolysis and fermentation.
What is anaerobic respiration?
Anaerobic respiration is respiration using electron acceptors other than molecular oxygen (O2). Although oxygen is not used as the final electron acceptor, the process still uses a respiratory electron transport chain called physolmere; it is respiration without oxygen.
When does anaerobic respiration happen?
Anaerobic respiration occurs when the amount of oxygen available is too low to support the process of aerobic respiration. There are two main types of anaerobic respiration, alcoholic fermentation and lactic acid fermentation.
What is the equation for anaerobic respiration?
Some examples of anaerobic respiration include alcohol fermentation, lactic acid fermentation and in decomposition of organic matter. The equation is: glucose + enzymes = carbon dioxide + ethanol / lactic acid. Though it does not produce as much energy as aerobic respiration, it gets the job done.
