Cellular respiration (fermentation\anarobic respiration)

Question 1

T or F:
more ATP is made in fermentation then in glycolysis

Answer 1

False, since fermentation is an anarobic process it can not extract the same ammount of energy that the electron transport chain can

Question 2

How is NAD+ replenished in fermentation?

Answer 2

In fermentation the NADH gives its electrons to a derivative of pyruvate or pyrutave its self

Question 3

What ocors in alcoholic fermentation

Answer 3

Glycolysis yields 2 net ATP, 2 NADH, and 2 pyruvate. then the pyruvate goes through decarboxylation that yields 2 CO2 and 2 acetaldehyde. finally acetaldehyde reacts with the NADH and yields 2 ethanol

Question 4

What ocors in lactic acid fermentation

Answer 4

Glycolyisis yields 2 pyruvate and ATP. The pyruvate accept the electrons from NADH and FADH to yield 2 lactate and lactic acid.

Question 5

What step does fermentation start with

Answer 5

glycolysis

Question 6

in what step of fermentation is the ATP produced

Answer 6

glycolysis

Question 7

Why do our bodies use lactic acid fermentation

Answer 7

Because when we do strenuous exercise for long periods of time it takes longer for our cells to transport oxygen to our cells, causing anarobic respiration (fermentation)
