Every cell is selectively permeable to different molecules. This type of selectively is caused by a semi-permeable membrane, which allows the movement of certain molecules across it. Water exchange can be measured in two ways: RBC osmotic permeability is measured, and diffusional water permeability is measured (Benga and Borza 1995). …

The nucleus is the most obvious organelle in a eukaryotic cell. Virtually all eukaryote cells have a nucleus (red blood cells lose theirs and so are enucleate for most of their life-span of 180 days). It is surrounded by the nuclear envelope, a double membrane with contains a large number …

The cell membrane consists of mostly phospholipids and proteins which gives the cell its selectively permeable nature. The function and permeability of the cell membrane depends on its whole structure. When destroyed, the permeability of the cell membrane is disrupted causing cellular contents to leak out. When cells are cut, …

Step 1: Determine which GPCRs are associated with the peach scent. (3.5 pts) Insert the cDNA of all the olfactory GPCRs into E. coli and purify out all the olfactory GPCR proteins. For each GPCR protein, have one control reaction with just the GPCR, and one experimental reaction where the …

Introduction: By completing lab exercise 6 : Biologically Important Molecules, we are able to perform tests such as the Benedicts Test for Reducing Sugars, Iodine Test, Biuret Test, Sudan IV Test, and lastly the Grease-Spot Test that detect the presence of biologically important carbohydrates, protein lipids and nucleic acids. Most …

Unlike the abdominal viscera, the thoracic viscera are separated into two cavities by an area called the mediastinum. What is the clinical importance of this compartmental arrangement? The clinical importance of this compartmental arrangement is that the mediastinum region contains a lot of major and essential parts of the human …

Mg2+ has 10 electrons. A magnesium atom has 12 electrons with 2 of the 12 being valence electrons. Therefore the atom will lose the valence electrons which are located on the outermost shell to stabilize itself (outermost shell) as atoms tend to do what it easiest. Since magnesium lost 2 …

Cell membrane: The cell membrane surrounds the cytoplasm of a cell and its job is to protect the inside of a cell by only allowing certain substances into the cell and keeping other substances out. It also helps to support the cell and maintains its shape. Nucleus: This is the …

INTRODUCTION Myasthenia Gravis, (MG), which means “grave muscle weakness” is a disorder classified as a chronic autoimmune neuromuscular disease (NINDS, 2010). This disease causes weakness in the muscles of the peripheral nervous system. The more frequently the muscle is used, the more likely it is to be affected. Thus, the …
