Fermentation (easy)

Question 1

Ethanol Fermentation

and what are the waste products of ethanol fermentation

Answer 1

After glycolysis the two pyruvates lose a carbon atom that combines with oxygen to create Co2. After this the pyruvate turns into Acetaldehyde, then Acetaldehyde receives a H from NADH allowing it to go back to Glycolysis to aid more production of ATP.

Alcohol and ethanol

Question 2

Lactic Acid Fermentation

Answer 2

After glycolosis, unlike Ethanol, Lactate/Lactic Acid does not lose and carbon atom but just gains an H atom which makes the pyruvate turn into Lactate/lactic acid. This Lactate can be converted back into pyruvate in the liver. then the pyruvate can enter krebs to proceed CR

Question 3

are the amount of NAD+ limited in anaerobic pathwayhs?

Answer 3

yes and therefore this is significant because it makes NAD+ recycled and reused to process CR

Question 4

What is fermentation in a nutshell

Answer 4

when H atoms are transferred to an organic molecule(pyruvate)

Question 5

examples of Fermentation

Answer 5

bacteria
production of beer

Question 6

what is max percent of alcohol before yeast cells die

Answer 6

11-12%

Question 7

What are the waste products In glycolosis of non living organisms

Answer 7

alcohol and co2
