Physiology 2130 Study Guide - Final Guide: Peripheral Chemoreceptors, Respiratory Acidosis, Methanol
Document Summary
We will look at the relationship b/t hydrogen and acidity. Define what acids and bases are, what the ph scale is, and why it is important to maintain h+ at precise levels. Look at the different mechanisms in the body for regulating h+ concentrations (and thus ph) and we will also learn about some of the things that can alter the ph of the body. Many chemical reactions that take place in the body, and most of the machinery inside all cells, are sensitive to the presence of hydrogen ions. H+ can alter the shape of proteins that act as enzymes that speed up chemical reachtions. As a result, any change in the concentration of h+ will affect the activity of almost every cell. Therefore, it is essential that h+ concentrations be carefully regulated. Hydrogen atom: has a single proton, which is positevly charged, and a single electron, which is negatively charged, result=neutral element.
