Question

When a person is sprinting, the person's muscle cells will begin using anaerobic respiration in addition to keeping the mitochondria respiring aerobically as much as the oxygen supply will allow. What benefits do muscle cells gain from anaerobic respiration in this situation? When pyruvate is transformed into lactic acid, four more ATP molecules are produced that can power muscle movement while NAD+ is regenerated. The oxygen generated as a waste product during lactic acid fermentation can be used by the mitochondria to increase their output of ATP . Adding electrons from NADH to pyruvate regenerates NAD+ , so that glycolysis can continue, and produces lactic acid, a waste product that can diffuse out of the cell. Without using oxygen, the cell generates two ATP molecules that can keep the muscles moving for every glucose molecule that enters glycolysis.

Answer 1

There are two options from this list that would be elegible to respond to the question: What benefits do muscle cells gain from anaerobic respiration in this situation? Would be: 1. Adding electrons from NADH to pyruvate regenerates NAD+, so that glycolysis can continue, and produces lactic acid, a waste product that can diffuse out of the cell and 2. Without using oxygen, the cell generates two ATP molecules that can keep the muscles moving for every glucose molecule that enters glycolysis.

Step-by-step explanation:

Anaerobic respiration has a very positive thing and it is that it will provide the body with enough energy to be able to move suddenly, and for a period of time, while aerobic respiration takes over and provides further energy. In the case of this question, sprinting is a sudden increase in exercise that will require that the body provide enough energy from glucose to the muscles, before aerobic respiration can take over. Glycolysis, and anaerobic respiration, allows cells to generate the necessary ATP from glucose to power the muscles. Although this process is short-lived and has consequences, it also becomes vital for aerobic metabolism to be as productive as it is. One of the reasons is because some of the byproducts of glycolysis will move on to aerobic respiration and provide further sources for production of ATP. Also, as said, anaerobic respiration permits the muscles to be energized without having to have oxygen immediately available.
