In what way does hemoglobin act as a buffer against changes in blood ph?

Explanation:

Hemoglobin removes excess protons from the red blood cells so that they can be excreted through the kidneys.  

Hemoglobin binds some of the excess protons released by carbonic acid.  

Subsequent binding of oxygen is drastically reduced after the first one is bound.  

Hemoglobin produces protons or hydroxide ions as needed to alter the blood pH.

Excess acids in the red blood cells are removed by the hemoglobin

Explanation:

In what way does hemoglobin act as a buffer against changes in blood ph?

Excess acids in the red blood cells are removed by the hemoglobin . it is a good receptor of excess proton released by carbonic acid.

It helps to remove acids before it affects the PH of the blood. deoxygenated hemoglobin are better receptor of proton than the oxygenated one.

If hemoglobin does not act as a buffer, there will be changes  in the blood's PH and can poison the blood.

there are two significant figures.
