Cell Membrane Simple diffusion is when a small‚ non-polar molecule passes through a lipid bilayer. It is classified as a means of passive transport. In simple diffusion‚ a hydrophobic molecule can move into the hydrophobic region of the membrane without getting rejected. Simple diffusion does not involve a protein. An example of simple diffusion is osmosis. Hydrophilic molecules cannot participate in simple diffusion because they would move into the hydrophobic region of the membrane and be

Adkins or Fadkins Case Study Part One – 1. Proteins - Proteins are chains of amino acids. In general‚ proteins may be structural proteins used to build tissues‚ they may be enzymes that mediate chemical reactions‚ or they may be hormones. Examples of proteins would be channel proteins in cell membranes‚ collagen protein in the skin‚ actin and myosin in the muscles‚ and hemoglobin in red blood cells. Types of dietary sources would be‚ meat‚ milk‚ (both of which are not pure proteins‚ but are

AFFECT THE LEVEL OF ORGANIZATION? * THE KIDNEY There are two kidneys‚ each about the size of a fist‚ located on either side of the spine at the lowest level of the rib cage. Each kidney contains up to a million functioning units called nephrons. A nephron consists of a filtering unit of tiny blood vessels called a glomerulus attached to a tubule. When blood enters the glomerulus‚ it is filtered and the remaining fluid then passes along the tubule. In the tubule‚ chemicals and water are either
