Cellular Respiration
The process that releases energy (ATP) by breaking down glucose. (converts food molecules (glucose) into a form usable (ATP) by the organism)
Glycolysis
Converting glucose into ATP without the presence of oxygen. Net ATP=2, Location: cytoplasm
Alcoholic Fermentation
Type of anaerobic respiration used by organisms such as yeast to recycle products of glycolysis. Alcohol and Carbon Dioxide made, NO additional ATP made. Used in making beer, bread and wine
Lactic Acid Respiration
Type of anaerobic respiration used by organisms such as bacteria to recycle products of glycolysis. Lactic acid made, NO additional ATP made. Used in making cheese and yogurt
ATP
Adenosine triphosphate. Energy.
Pyruvic Acid
3 carbon sugar produced when glucose is split during glycolysis
Mitochondria
Organelle found in all organisms that is the site of aerobic cellular respiration
ATP synthase
Enzyme that helps make ATP
Krebs Cycle
Second Step in aerobic respiration that takes pyruvic acid from glycolysis to produce carbon dioxide and high energy electrons. Takes place in mitochondria. Net gain of 2 ATP.
Electron Transport Chain
Third step of aerobic respiration that take the high energy electrons from the Krebs cycle to change ADP to ATP. takes place in mitochondria. Net gain of 32-34 ATP
Anaerobic Respiration
Does not use oxygen
Aerobic Respiration
Uses oxygen
Glycolysis
The first step of cellular respiration
Cytoplasm
Place where cells perform glycolosis
Krebs Cycle and Electron Transport Chain
process occurring in the Mitochondria
Steps 2 and 3 of Cellular Respiration.
Cellular Respiration Chemical Equation (Formula)
C6H12O2 + 6O2 ------> 6CO2 + 6H20 + Energy (ATP)
