True.

Explanation:

In Biology, blood pH can be defined as a measure of the hydrogen ion (H¯) concentration of blood i.e the level of alkalinity or acidity of blood.

Basically, the normal blood pH of a human being should be between 7.35 and 7.45.

Hence, one of the ways in which the body regulates blood pH is with proteins by accepting and releasing hydrogen ions. Typically, when the blood pH falls, the hydrogen ions (H¯) are accepted (absorbed) while hydrogen ions are released when the blood pH rises.

A protein such as haemoglobin which makes up a composition of the red blood cells, binds an amount of acid required to regulate blood pH.

Hence, the substance that makes the blood red is an iron containing protein known as hemoglobin.
