Cellular Respiration
Process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
Aerobic respiration
Converting glucose into ATP in the presence of oxygen. Glycolysis, Kreb's cycle, ETC, total of 36-38 ATP, Location: mitochondria
Anaerobic Respiration
Converting glucose into ATP without the presence of oxygen. Glycolysis only, 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
Glycolysis
First stage of anaerobic AND anaerobic cellular respiration. Breaks glucose down into two pyruvic acid molecules, net gain of 2 ATP.
ATP
Adenosine triphosphate. Energy.
Pyruvate
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
Protein that helps make ATP
Krebs Cycle
Step in aerobic respiration that takes pyruvate from glycolysis to produce carbon dioxide and high energy electrons. Takes place in mitochondria. Net gain of 2 ATP.
Electron Transport Chain
Step of aerobic respiration that take the high energy electrons from the Krebs cycle to change ADP to ATP. 34 ATP is made
Anaerobic Respiration
Does not use oxygen
Aerobic Respiration
Uses oxygen
Fermentation
When oxygen is NOT present in anaerobic cellular respiration.
Glycolysis
The first step of cellular respiration
Cytoplasm
Place where cells perform glycolysis
Krebs Cycle and Electron Transport Chain
Processes occurring in the Mitochondria
Steps 2 and 3 of Cellular Respiration.
Definition of Cellular Respiration
The process of breaking the chemical bonds of glucose into energy.
