A group of scientists is investigating the effects of exercise intensity on the rate of lactic acid production in muscle cells. According to the data that they gathered, they able to observe a increasing level of lactic acid during strenuous exercise compared to moderate-intensity exercise, which of the following is BEST conclusion for their data?
Question
A group of scientists is investigating the effects of exercise intensity on the rate of lactic acid production in muscle cells. According to the data that they gathered, they able to observe a increasing level of lactic acid during strenuous exercise compared to moderate-intensity exercise, which of the following is BEST conclusion for their data?
Solution
The best conclusion for their data would be that higher intensity exercise leads to increased production of lactic acid in muscle cells compared to moderate-intensity exercise. This could be due to the fact that during strenuous exercise, the body's demand for energy exceeds the oxygen supply, leading to anaerobic respiration in the muscles, which produces lactic acid.
Similar Questions
It's believed that by experiencing high intensity intervals that produce lactic acid in muscles, the body adapts and burns lactic acid more efficiently during exercise. How does this impact the athlete?
lactic acid is produced whenever muscle tissue contracts. Muscle tissue can contract in the absence of oxygen and lactic acid accumulates until fatigue sets in. On return to Aerobic conditions, the muscle tissue can contract again and the lactic acid is metabolised. Which of the following is the best interpretation of these observations?: A= formation of lactic acid is oxygen dependent, B= in anaerobic conditions, lactic acid is produced faster then it can be removed,C= lactic acid is produced only in anaerobic conditions,D= muscle contraction is independent of oxygen availability.

Why is lactate produced during strenuous exercise? A. Laktaat maak die bloed suur (asidose) wat ensiem funksie bevorderLactate makes the blood acidic (acidosis) which promote enzyme function. B. Rooibloedselle werk harder tydens oefening en produseer dus meer laktaat.Red blood cells work harder during exercise and thus produce more lactate. C. Om die NADH wat ophoop, om te skakel na NAD sodat glikolise bly funksioneer.To convert the accumulating NADH to NAD so that glycolysis keeps functioning. D. Dis 'n produk van lipied katabolisme.It is a product of lipid catabolism.
