3.1 BIOLOGICAL MEMBRANES 3.1.1 Properties of Cell Membranes • Separates living cell from its nonliving surroundings. • 8 nm thick. • Selectively permeable - allows some substances to cross more easily than others. 4.1.2 Fluid Mosaic Model • Singer and Nicolson (1972) - plasma membrane is a mosaic of proteins dispersed within lipid bilayer‚ with only bilayer‚ the hydrophilic regions exposed to water. Hydrophilic region of protein Phospholipid bilayer Hydrophobic region of protein

Assessment 2 – Congestive Cardiac Failure 1. Mr Wright’s admission states that he has CCF (congestive cardiac failure). Clearly define CCF. What organs and which body systems are affected by this disorder? Congestive cardiac failure defined Congestive cardiac failure (CCF) is a progressive disease of the heart‚ which involves loss of pumping ability by the heart. Congestive cardiac failure occurs when the myocardium loses its ability to pump enough blood to meet the body’s metabolic needs and is

Diagnostic Urinalysis Lab Introduction/Background Today’s lab exercise is about diagnostic Urinalysis. Urine reflects the many chemical components found in blood. This test is a good measure of health of endocrine system‚ kidneys‚ and urinary tract. Artificial urine samples are used for today’s lab thank goodness. The test that this lab is mostly focused on is called “dipstick” urinalysis test where students will analyze the chemical composition of urine by dipping the chemical indicator stick or

Bowman’s capsule – forming a blind-ending capsule around a knot of capillaries called the glomerulus (the site of filtration) 2. Proximal convoluted tubule (the site of bulk-phase reabsorption & some secretion) 3. Loop of Henle (where the concentration & dilution of urine mainly occur) 4. Distal convoluted tubule (the site of ‘fine-tuning’ reabsorption

Maintaining a Balance Enzymes 1.1 Identify the role of enzymes in metabolism‚ describe their chemical composition and use a simple model to describe their specificity on substrates Enzymes are biological catalysts‚ meaning they are organic and speed up a chemical reaction without taking part in it. This means it has a vital role in metabolism where it ensures that the chemical reactions that make up metabolism can function fast enough to sustain life by lowering activation energy. Metabolism

TOPIC 6‚ 11‚ & OPTION H: HUMAN HEALTH AND PHYSIOLOGY Digestive System Includes all the structures that are concerned with bringing food into the body to provide for the needs of the body’s cells. Each cell in an organism relies on a continuous expenditure of energy. Fats‚ carbs‚ and proteins are broken down during cellular metabolism and the energy derived from them is used to make ATP. The digestive system deals with: Ingestion‚ which is the bringing of nutrients into the body. Mechanical
