Question

Question 23 (1 point) You are given a sample taken from a living organism but are not told what kind of organism, only that it was denied oxygen in the container which held it. If you did a biochemical analysis, what would most likely be present in a sample of this organism? O a) NAD+ b) alcohol c) oxygen d) lactic acid b) or d)

Answer 1

Ans: We know that the decrease in the concentration of oxygen because of the lack of circulation causes a dramatic switch from aerobic to anaerobic metabolism. Anaerobic metabolism does not require the presence of oxygen to convert raw materials into energy.The body relies on anaerobic respiration when a sudden burst of energy is required in a short amount of time.There are two main types of anaerobic respiration: alcoholic fermentation and lactic acid fermentation. Alcoholic fermentation is the process of converting glucose into the molecule ethanol. This process is generally done by microscopic organisms like bacteria and certain fungi like yeast. Lactic acid fermentation occurs in animals after glycolysis if there is not enough oxygen to perform aerobic respiration.

Thus,Alcohol or Lactic acid anything can be present in the sample and hence the answer is b) or d)
