Answer:
The correct answer will be option-C
Explanation:
In anaerobic conditions or when the oxygen is limited, the pyruvate enters the anaerobic respiration.
During heavy exercise when the ATP is required in high amount then then oxygen is also required in high amount but due to lack of oxygen, pyruvate formed as a result of the glycolysis is converted to lactate. Lactate acts as electron acceptor taking the role of the oxygen.
This lactic acid diffuses into the blood plasma which is then carried to the liver. In the liver Cori cycle converts the lactate back to the pyruvate form or glucose form.
Thus, option-C is the correct answer.
A is the correct answer because saliva cannot be infected and HIV can't travel through skin.
