Question

atp and anaerobic cellular respiration
how much atp does fermentation \cost\?
how many atp does fermentation produce
how many atp does fermentation \profit\?

Explanation:

Step1: Determine ATP cost in fermentation

Fermentation starts with glycolysis. Glycolysis uses 2 ATP in the investment phase. So the ATP cost is 2.

Step2: Determine ATP production in fermentation

Glycolysis, which is the main part of fermentation, produces 4 ATP in the pay - off phase. So the ATP produced is 4.

Step3: Calculate ATP profit

Profit = ATP produced - ATP cost. So, $4 - 2=2$.

Answer:

How much ATP does fermentation “cost”?	How many ATP does fermentation Produce	How many ATP does fermentation “profit”?
