Question

People who suffer from a heart attack often have an increased ratio of lactic acid to pyruvic acid in their hearts. What does this observation say about the availability of oxygen in the heart muscle cells of someone who has had a heart attack? How could you use this information to screen people who might be at risk for a heart attack?

Answer 1

The fact that they have a lot of lactic acid in their muscles shows they go through anaerobic respiration. A lack of oxygen leads to anaerobic respiration which produces lactic acid. You could test the pyruvic acid to lactic acid in the heart. Another option could be testing the availability of oxygen in the heart.

Answer 2

Heart attack occurs due to anaerobic respiration.

Step-by-step explanation:

This observation say about the availability of oxygen in the heart muscle cells of a person who has had a heart attack because due to unavailability of oxygen to the heart cells, anaerobic respiration occurs that produce lactic acid. If the oxygen is available to the heart cells, they produce pyruvate acid and no heart attack will occur to the person so people should anaerobic respiration in order to avoid heart attack.
