Question

what caused co2 in the blood to decrease?

increased cellular respiration

exercise

hyperventilation

All of the listed responses are correct.

None of the listed responses is correct.

Answer 1

Answer:

All given reasons are correct for the decrease of Co2 in blood.

1. Increase in cellular respiration:

In human being a very high metabolic activity take place in the form of a cycle. This cycle is known as Kerb cycle, result of this cycle is generation of energy in the form of ATP (Adenosine tri phosphate) in cellular respiration a huge amount of oxygen utilized by cells and excretion of carbon dioxide. If this cellular respiration occurs with very high rate it can cause a decrease of Co2 in blood vessels.

2. Exercise:

Exercise also can be reason for decrease of Co2 in blood because during physical exercise body utilized more energy than normal condition it increase this kerb cycle and higher breathing rate so excretion Co2 from body also must be in higher amount so it can be a reason for decrease of Co2 in blood.

3. Hyperventilation:

Hyperventilation is condition in which breathing rate is very higher compared to the normal condition. If breathing rate is higher than naturally inhale oxygen and exhale carbon dioxide in huge amount. During this process blood vessels are comes in narrow state and supply of blood to the brain very slow it can cause death of any human being.

Hyperventilation is the main cause of decrease of Co2 in blood.
