Lab 7 Alcoholic Fermentation

Adenosine Triphosphate (ATP)

the cell's energy currency

Cellular respiration

Glucose is broken down into carbon dioxide. This releases electrons and hydrogen ions which are "carried" by NAD+

Glycolysis

An anaerobic process that occurs in the cytoplasm

Aerobic Process

Requires oxygen that occurs in the mitochondria and produces 34-38 ATP

Fermentation

a way to recycle the NADH that is produced during glycolysis back to NAD+ in the absence of oxygen

Alcoholic Fermentation

produces carbon dioxide and ethanol as byproducts. Allows a cell to continue to produce ATP and meet its energy needs when oxygen is no longer available

C3H4O3

Pyruvate formula

C3H5OH

Ethanol formula

C6H12O6 → 2C3H4O3 + 2 net ATP + 2 NADH

Glycolysis formula

2C3H5OH + 2CO2 + 2 NAD+ + 2 H+

Fermentation formula

C6H12O6 + 6O2 → ATP + 6CO2 + 6H2O

Cellular respiration formula

Corn syrup, table sugar, artificial sweetener
