Cellular Respiration

The process that releases energy (ATP) by breaking down glucose. (converts food molecules (glucose) into a form usable (ATP) by the organism)

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.

Cellular Respiration Chemical Equation

C6H12O2 + 6O2 ------> 6CO2 + 6H20 + Energy (ATP)
