Cellular Respiration
This flashcard set explains the key stages and components of cellular respiration, including glycolysis, the Krebs cycle, and the production of ATP. It also provides the overall equation for cellular respiration and highlights carbon dioxide as a waste product.
cellular respiration
Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen

Key Terms
cellular respiration
Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
ATP
(adenosine triphosphate) main energy source that cells use for most of their work
Glycolysis
Splitting of a 6-carbon glucose into two pyruvates, each having 3 carbons.
cellular respiration equation
C6H12O6+6O2---> 6CO2+6H2O+ATP
Carbon Dioxide
waste product of cellular respiration
Krebs cycle
produces molecules that carry energy to the second part of cellular respiration

alcoholic fermentation | the anaerobic process by which yeasts and other microorganisms break down sugars to form carbon dioxide and ethanol |
function of cellular respiration | Cellular respiration is what cells do to break up sugars into a form that the cell can use as energy. Cellular respiration takes in food and uses it to create ATP, a chemical which the cell uses for energy. |
citric acid cycle | Another name for the Krebs cycle |
Cellular | occurs in the cell |
