How does cellular respiration compare with lactic acid fermentation?
Cellular respiration uses oxygen in the chemical reaction that releases energy from food. Fermentation occurs in an anaerobic or oxygen-depleted environment. Because fermentation doesn’t use oxygen, the sugar molecule doesn’t break down completely and so releases less energy.
What is the energy conversion during cellular respiration?
Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body’s cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
How many more ATP can be produced by cellular respiration in comparison to lactic acid fermentation?
aerobic respiration process breaks down a single glucose molecule to yield 38 units of the energy storing ATP molecules. For the lactate fermentation, 2 molecules of ATP are produced for every molecule of glucose used.
How is fermentation related to cellular respiration?
Cellular respiration, like burning, results in the complete oxidation of glucose into CO2 and water. Fermentation, on the other hand, does not fully oxidize glucose. Instead, small, reduced organic molecules are produced as waste. As a result, cellular respiration releases more energy from glucose than fermentation.
What is the main purpose of cellular respiration and fermentation?
Cellular respiration and fermentation produce energy for cells to use. Any chemical process that yields energy is known as a catabolic pathway. For nearly all organisms on Earth (except chemolithotrophs), that energy is stored in organic molecules.
What is the importance of fermentation to cellular respiration quizlet?
Fermentation supplies glycolysis with NADP+ to keep it going. In cellular respiration, ATP is produced during glycolysis, the Krebs cycle, and the electron transport chain.
What is the main difference between aerobic and anaerobic respiration give one example of each?
Aerobic respiration needs oxygen to occur, while anaerobic does not. This presence of oxygen determines what products will be created. During aerobic respiration, carbon dioxide, water, and ATP are produced. During anaerobic respiration, lactic acid, ethanol, and ATP are created.
What are the characteristics of aerobic respiration?
Aerobic respiration is the process by which organisms use oxygen to turn fuel, such as fats and sugars, into chemical energy. In contrast, anaerobic respiration does not use oxygen. Respiration is used by all cells to turn fuel into energy that can be used to power cellular processes.
What is the primary function of oxygen in aerobic respiration?
Aerobic respiration uses oxygen to break down glucose, amino acids, and fatty acids and is the main way the body generates adenosine triphosphate (ATP), which supplies energy to the muscles.
