Question

Acquiring an oxygen debt is evidence that
A. Oxygen cannot be stored in tissue.
B. Aerobic respiration is more complex than glycolysis.
C. Lactic acid can be converted into glycogen
D. Anaerobic processes are slower than the anaerobic process.

Answer 1

Hint: The condition where deficiency of oxygen occurs within the body is known as oxygen debt. Deficiency of oxygen can be caused by several reasons like an intense workout, effect of diseases. To restore the deficient oxygen body tends to breathe rapidly and spontaneously.

Complete answer: When we do intense exercise, our blood circulation increases and blood vessels are dilated. This condition is formed due to the supply of required oxygen to every cell of the body. The supply of required oxygen occurs for a certain time. After a certain time, the body can’t supply enough oxygen to the body cells. This condition leads to the formation of oxygen deficiency in the body. To restore the condition, the body undergoes a certain. At that moment, the supply of oxygen occurs by the process called anaerobic respiration. Anaerobic respiration involves the conversion of pyruvic acid into lactic acid. Converted lactic acid was then transferred to the liver. Within the liver glucose or glycogen is produced from lactic acid. Produced glucose is then used to generate energy for maintaining body activities.
So, the correct answer is “Option A”.

Additional Information: The process by which chemical energy is converted to functional energy through a series of the metabolic pathway is called cellular respiration. The process results in the production of ATP. Cellular respiration is two types, named aerobic respiration and anaerobic respiration.

Note: Oxygen deficiency in the body is restored by anaerobic respiration. Anaerobic respiration does not involve the presence of oxygen it uses an electron acceptor. The process occurs within the cytoplasm of the cell. Lactic acid fermentation and alcoholic fermentation are examples of anaerobic respiration.
