glucose galactose milk sugar Complex more than 2 molecules of CHO polysaccharides Starch storage carbohydrate for plants Glycogen storage carbohydrate for animals Recommended amount for carb is an energy source 225325 grams 45 to 65 of total caloric intake come from carbs Protein Sparing protein is normally used for maintenance repair and growth of tissues however when CHO reserves are reduced metabolic pathways exist for the synthesis of glucose from protein Therefore your body uses tissuetissue protein for energy 3 Metabolic Primer for fat to be used as an energy source it must be preceded by CHO metabolism Fuel for the central nervous system the brain uses glucose almost exclusively as a fuel and essentially has no stored supply of this nutrient Types of lipids from milk lard eggs meat 1 Triglycerides most of fat in body 2 Phospholipids 3 Steroids saturated single bonds between carbon atoms animal products beef lamb pork chicken egg yolk dairy fats cream butter milk cheese

different amino acids used to make proteins Essential amp nonessential proteins Essential proteins there are 9 of these out of the 20 proteins are ones that our own body cannot produce It needs these proteins from the food we take in like meats or soy Nonessential as you may have guessed are ones that we produce on our own so we don39t need to worry about them Fibrous Proteins used for building

Vitamins are organic molecules and subclassi ed into fat soluble amp water soluble Minerals Constitute about 4 of total body weight and are most concentrated in the skeleton Minerals are inorganic molecules Water molecules Within the cell 3040 Outside the cell 6070 Cell anatomy the study of cellular structures Cell physiology the study of cellular function Cell Theory 1 Cell is basic structural amp functional unit of living organism 2 Organism depends on both the individual and combined activities of its cells 3 Biochemical activities of cells are dictated by their shapes 4 Cells can arise only from other cells 3 Main Parts to a Cell Plasma Cell Membrane 2 Cytoplasm and Organelles 3 Nucleus Membranes found on the outer surfaces of all cells plasma membrane membranes are the major component of organelles membranes are made up of lipids protein and carbohydrate Membranes are mostly made up of lipid and protein 60 protein and 40 lipid membranes are the directors of what comes in and what goes out of the cell sites for chemical reactions membranes are the type of lipid found in the membrane is a Phosoholipid Properties of the phospholipid bi layer 1 Little if any structural support 2 Powerful barrier to most molecules of biological interest such as a particles with electrical charges Na K Ca gt IONS b large molecules have a hard time crossing c water generally moves freely across 3 Generally interspersed with proteins Glycocalyx Made of glycoproteins amp glycolipids Cholesterol Stabilizes the membrane Decreases mobility of phospholipids amp decreases uidity of

proteins Properties of the lipid biayer a structural support b transport of molecules across the membrane c enzymatic control of chemical reactions at cell surface d receptors for hormones and other regulatory molecules einterceuarjoining CAM s f cell to cell recognition Diabetes type Insulin Dependent Diabetes Mellitus IDDM Juvenile Onset Diabetes Usually occurs before age 15 Totally lack insulin activity Beta cells of the pancreas stop producing insulin No insulin no glucose in the blood stream no ATP Non Insulin Dependent Diabetes Mellitus NIDDM Adult Onset Diabetes Usually occurs after age 40 amp increasingly common with age Hereditary or familial predisposition is common in Type II Diabetes Type II VVVV V Insulin is still produced by pancreatic beta cells however amount is inadequate or the insulin receptors are unresponsive Individuals are commonly over weight and lack regular physical activity Three ways cells can be bound to each other Tight junctions impermeable junction use indigro proteins plasma membrane connects to another cells plasma membrane not allow other molecules to move inbetween cells Desmosomes anchoring junctions celluar velcrow kertain llaments they allow the sheet of cells to undergo stress Gap junctions communicating junction small channels that connect cytoposm to other cells cytoposm Two ways substances cross membrane Passive processes no energy required Active processes energy ATP required Types of passive transport Diffusion Simple diffusion Carrier and channelmediated facilitated diffusion Osmosis diffusion of water Simple diffusion Nonpolar lipidsoluble hydrophobic substances diffuse directly through phospholipid bilayer lipid soluabe means it can pass thru Examples oxygen carbon dioxide fatsoluble vitamins Facilitated diffusion Certain hydrophobic molecules are transported passively down their concentration gradient by Carriermediated facilitated diffusion Channelmediated facilitated diffusion Osmosis Diffusion of a solvent Movement of solvent such as water across a selectively permeable membrane Water diffuses through plasma membranes Through lipid bilayer Aquaponn Flow occurs when water concentration is different on the two sides of a membrane Two major active membrane transport processes Active transport some sort of protein that going to allow ions into the cell Vesicular transport using vesicles found in the cell to move particles from the external celluar enviorment to internal enviorment Both require ATP to move solutes across a plasma membrane for any of these reasons Solute is too large for channels Solute is not lipid soluble Solute is moving against the concentration gradient Active transport Primary active transport Required energy comes directly from ATP hydrolysis ATPgt ADP PEx Sodium Potassium Pump Secondary active transport Required energy is obtained indirectly from ionic gradients created by primary active transport Ex After sodium is pumped out of cell NaK pump Na moves along concentration gradient or leaks back into the cell through a carrier protein and can bring with it or cotransport other subctances amino acids glucose etc Requires carrier proteins solute pumps Bind speci cally and reversibly with substance being moved Moves solutes against their concentration gradient from low to high This requires energy ATP I Vesicular Transport Endocytosis transport into cell Involves transport of large particles macromolecules and uids across the membrane in sacs called vesicles Requires cellular energy usually ATP 3 different types of endocytosis phagocytosis pinocytosis receptormediated endocytosis Exocytosis transport out of cell Transcytosis transport into across and then out of cell Vesicular traf cking transport from one area or organelle in cell to another Plasma membrane Protects and allows substances to enter or exit the cell through diffusion facilitated diffusion osmosis active transport and vesicular transport Cytoplasm Serves as the substance in which chemical reactions occur Contains organelles Histology Fixed sectioned stained Study of tissues Roles of Epithelial Tissue 1 Protection 2 Absorption 3 Filtration 4 Excretion 5 Secretion 6 Sensory reception Simple epithelia Strati ed epithelia Pseudostrati ed epithelia Glandular Epithelia O Gland One or more cells that make or secrete a product The quotproductquot is referred to as a secretion Glands are classi ed according to two sets of traits Where they release their product Number of cells docrine internallv secretin0 Hormones messenger chemicals Through

in ammatory response is a relatively nonspeci c reaction that develops quickly wherever tissues are injured immune response response is extremely speci c but slower Tissue repair requires that cells divide and migrate o This is initiated by growth factors wound hormones released by injured cells 0 It occurs in 2 major ways by regeneration and by brosis 0 Depending on the type of tissue injured
