Question
After taking a long deep breath we do not respire for some seconds due to(a) more $\mathrm{CO}_{2}$ in blood(b) more $0_{2}$ in blood(c) less $\mathrm{CO}_{2}$ in blood(d) less 0, in blood.
Step 1
This leads to the tight binding of oxygen molecules with the hemoglobin in the red blood cells (RBCs). Show more…

You should be able to hold your breath longer than normal after you hyperventilate (breathe rapidly for a while) because hyperventilating a. decreases blood oxygen levels. b. decreases blood carbon dioxide levels. c. increases blood oxygen levels. d. increases blood carbon dioxide levels.
In humans, the urge to breathe results from high concentrations of $\mathrm{CO}_{2}$ in the blood; there are no direct physiological sensors of blood $p \mathrm{O}_{2}$ Skindivers often hyperventilate (breathe rapidly and decply for several minutes) just before making a dive in the belief that this will increase the $\mathrm{O}_{2}$ content of their blood. (a) Does it do so? (b) Use your knowledge of hemoglobin function to evaluate whether this practice is useful.
When CO2 concentration in blood increases , breathing becomes A. There is no effect on breathing B. Slow and deep C. Faster D. Shallower and slow
