Question

Question 15 of 25 > Attempt 5 The pyruvic acid from glycolysis can be converted to acetic acid, which can enter the citric acid cycle. Because this process is a cycle, the atoms entering the cycle must balance the atoms that leave. Consider carbon balance in the citric acid cycle. How many Co, molecules leave the cycle for each acetic acid molecule that enters? For this question, assume that carbon only enters as acetic acid and exits as CO2. Note that acetic acid has two carbon atoms. You can determine the number of carbon atoms in carbon dioxide from its formula, co, CO, molecules: 2 Using the first answer, how many molecules of Co, are directly generated by the citric acid cycle from 4 molecules of acetic acid? Again, in this question, assume that carbon only enters as acetic acid and exits as co answer, how many more co, molecules: I TOOLS XTOY

Answer 1

Answer:

8 CO2

Explanation:

Each acetic acid produces 2 CO2 molecules by each citric acid cycle.

Therefore, 4 Acetic acid * 2 CO2 = 8 CO2 molecules
