Question

During anaerobic conditions the rate of glycolysis increases is called
A. Compensation point
B. Extinction point
C. Warburg effect
D. Pasteur effect

Answer 1

Glycolysis mostly takes place in anaerobic conditions i.e., in the absence of oxygen it is because it produces minimal amounts of ATP in the absence of oxygen rather than the aerobic conditions for the proper cellular respiration. Pasteur discovered this mechanism of glycolysis in anaerobic conditions.

Complete answer:
COMPENSATION POINT: This is evaluated to check the rate of photosynthesis with rate of respiration, it is the point where the light with certain intensity shows the amount of carbon dioxide and oxygen used or released in the respiration activity during the process of photosynthesis. This option does not seem to be linked with the glycolysis or the anaerobic respiration.
So, option A is not correct
EXTINCTION POINT: This point in respiration is observed only in the aerobic conditions it shows the relationship between rate of respiration and oxygen activity i.e. at this point the oxygen is
Released 4-10% this point cannot be observed in anaerobic condition.
So, option B is not correct
WARBURG EFFECT: The pyruvate produced in glycolysis is converted into lactic acid at anaerobic conditions but it does not help in high production of ATP.
So, option c is not correct
PASTEUR EFFECT: This effect inhibits the enzyme phosphofructokinase in turn inhibiting the production of oxygen in the glycolysis process. During this process it consumes less glucose to produce more energy which is ATP by increasing the rate of glycolysis.

Hence, the correct answer is option (D).

Note: The Pasteur method was first described by Louis Pasteur in yeast cells as they seem to exhibit high activity in the absence of oxygen other than the presence of oxygen hence from the Pasteur Effect was introduced to observe in the glycolysis process. Production of glucose with a large amount of ATP energy is crucial for the nutrition process along with respiration. Hence, Pasteur Effect is highly prioritized as it helps in production of 16 to 18 times more ATP other than the aerobically oxidized glucose.
