Compare/Contrast Fermentation and Cell Respiration

Question 1

Similarities of fermentation and cell respiration

Answer 1

Both Cellular respiration and fermentation result in the production of energy (ATP)
Both use ATP to produce a net gain of ATP
Glycolysis happens in cytoplasm of both eukaryotes and prokaryotes
Both use energy carrier NAD+ to carry electrons

Question 2

Differences of fermentation

Answer 2

Fermentation can occur without oxygen
There are two forms of fermentation: lactic acid and alcoholic.
Fermentation is a cycle
Lactic acid fermentation products - lactic acid
Alcoholic fermentation products - carbon dioxide and ethanol
Net Gain of 2 ATP

Question 3

Differences of Cell Respiration

Answer 3

Cellular respiration produces 36 ATP molecules where fermentation produces 2 ATP
respiration depends on the presence of oxygen
cellular respiration needs a molecule of glucose to begin the process
Has Krebs cycle and chemiosmosis/electron transport chain extra stages.
Happens in mitochondria (eukaryotes); cell membrane (prokaryotes)
