AA build-up of lactic acid
BA build-up of nitric oxide
CA build-up of uric acid
DA build-up of ethyl ether
Answer & Solution
Correct answer: A. A build-up of lactic acid
1. Muscle cells hold a very high concentration of mitochondria because movement demands energy.
2. When cells do not get enough oxygen they cannot make much ATP.
3. The small amount they do make in the absence of oxygen comes with the production of lactic acid.
4. Carbon dioxide is the waste of oxygen-using respiration, so it is not what marks the oxygen-poor route.
5. Lactic acid accompanies the low-oxygen output.
