Anaerobic Fermentation

Question 1

anaerobic fermentation 

Answer 1

a metabolic pathway that occurs
in the absence of oxygen. Involves
glycolysis, followed by further
reactions that convert pyruvate
into lactic acid in animals, or
ethanol and CO2 in yeasts

Question 2

Why can’t we just use Glycolysis to get a yeild of 2 ATP instead of fermentation

Answer 2

for glycolysis to
continue indefinitely and keep producing energy, the cell must still find a way to convert
NADH back to NAD+, which is an input of glycolysis, without the use of oxygen.

Question 3

Input and Outputs of Yeast

Answer 3

2 Pyruvate 2 NAPH 2ATP , 2 Ethanol 2 CO2 2NAD+ ( 2 Ethanol + ATP + 2CO2)

Question 4

Inputs and Outputs of Animals

Answer 4

2 Pyruvate 2 NAPH 2ATP , 2 Lactic Acid 2NAD+ ( 2 Lactic Acid + ATP )

Question 5

Sustainability and Speed

Answer 5

Cannot continue indefinitely due to
toxic build-up of lactic acid or ethanol, Fast
