Document Summary
Chapter 2 - genetics & evolutionary roots of behavior. There are many different kinds of cells in our bodies: Red blood cells: contain large amounts of a protein called hemoglobin. Hemoglobin picks up oxygen when red blood cells pass through the lungs and then drops off the oxygen when these cells pass through the body"s other tissues. Intestinal goblet cells: found in the lining of small intestine, manufacture granules of a protein called mucigen. When a goblet cell releases mucigen granules into the intestine, they combine with water to make mucin, a component of the mucus that lubricates the intestine. that absorbs light. Retinal photoreceptors: rod cells, which serve as light detectors in the eye, contain a protein called rhodopsin. Biological influences on behavior are governed by genes. Genes - sections of dna molecules, stored within chromosomes in every cell, that describe the structure and expression of specific proteins.
