They comprise both disaccharides and polysaccharides. ▪ Examples are Glucose‚ Galactose and Fructose. o • Isomers • Chemicals that share the same chemical formula but different structures (mirror images) • • Glucose “the blood sugar” • The primary source of energy in all living things • • Galactose • • Fructose “fruit sugar” Isomerization

Lab 2101 Instructor: Alan Byboth‚ M.S. 10/4/12 Abstract- The cell is invaluable building block of all biological life on this planet‚ and one of its most important and unique characteristics is its ability to be selectively permeable with its plasma membrane. This outer membrane’s sophisticated mechanisms of transport through its bilayer are vital in maintaining homeostasis in the cell and the entire body. To further understand these mechanisms‚ which can be further described as passive and

Tick (v) if it is a true statement. Chapter 2 Cell Structure and Cell Organisation 1. The cell is the basic unit of life for all organisms. 2. All cells have the same shape and size. 3. All cells have a plasma membrane‚ nucleus and cytoplasm. 4. Protoplasm consists of a plasma membrane and nucleus. 5. The nucleus consists of chromosomes and a nucleolus. 6. Organelles that are found in the cytoplasm of a cell include the nucleus‚ vacuole‚ endoplasmic reticulum‚ mitochondria and Golgi apparatus.

Absorption: “The intake of those small molecules through the plasma membrane and into the cells”. Egestion: “The removal of waste products not used in the metabolism e.g. Cellulose & faeces”. Metabolism: “All ongoing chemical and biological reactions in the body”. Organs of excretion: Skin: Salt and water

Post assessment will be done weekly basis for 8 weeks and then at 6 months after the completion of the 8 week diabetes prevention program. Except the fasting blood test which will be done only at the completion of 8th week and then 6th month follow up. The post assessment is valid tool to evaluate

Osmosis The purpose of this lab is to study how membranes of plant and animal cells react when exposed to different solutions. The first experiment involves purple onion skin and the second involves rat blood in various solutions. I needed to understand certain terms before preforming this lab to be able to efficiently explain what is happening to the cells. Diffusion is the tendency of a substance to move down its concentration gradient from a more concentrated to a less concentrated area.

The Biological Importance of Water for Living Organisms Water is made up of two elements‚ 2 positively charged hydrogen molecules and one negatively charged oxygen molecule. Water molecules have uneven charge distribution as one end of the molecule is slightly positive and the other slightly negative‚ this is called polar. Ionic substances such as sodium chloride dissolve easily in water because the positively and negatively charged ions are separated due to the dipole nature of water. As water

Absorption: "When absorbing‚ the peak plasma levels of celecoxib occur approximately 3 hrs after an oral dose. Under fasting conditions‚ both peak plasma levels and area under the curve are roughly dose-proportional up to 200 mg twice daily; at higher doses there are less than proportional increases in plasmas levels and the curve."
