Test 1 Physiology

Enzyme Pathway/Eukaryotic

What is the enzyme pathway? (6) phyenlalanine(amino acid)> tyrosine(AA or amino acid)>Levodopa>dopamine>norepinephrine>epinephrine(adrenaline)
Tyrosine Malanin. Changes pigments, ie albino is enzyme deficiet. Enzyme tyrosinase combines with substrate tyrosine
Phyenylalanine Builds up casing retardation. PKU test in babies. Disease called phenlketonuria(retardation).
Diet Soda Ingriedients Aspartane>>> Phenylamine + aspartic acid
Tyrosine Converts to Levodope(L-dopa) with right enzyme converts to dopamine
In Born Error in Metabolisim Amino Acid Metabolisim-PKU increase=retardation Carbohydrate Metabolisim-Lacose intolerance-lactose not utilized. Africa low tol. Lipid Metabolisim-Tay-Sach's disease is lipid accumulation affects brain also hypercholestrolemia high Cholestrol
Eukoryotic Cell Cell organelles . Cells for humans and animal
How many genes have DNA codes for 40,000
Flagella Sperm locomotion
Cilia hairlike projection ourside cell. ie. lungs with coughing up phlegm
Describe the order from the Nucleus of a cell or the making of a protein sequence starting with Copy from DNA Nucelues, messenger RNA, Rough Endoplasmaic Reticulum with ribosomes, Smooth Enoplasmic Reticulum, /golgi Complex, secretory vesicle
What happens is lysomes rupture? Cell death and aging. Antioxidants help prevent again
ATP Adenosine triphosphate in midochondria. A-P-P-P phosphate breaks off to produce energy. 90% ATP made by mitochondria
How does it convert back to ATP ATP>>>ADP enzyme ATPsyntestase will release a P to form ATP
Why do we need energy? Mucles contraction and horomone activation
Mitochindria Inner/Outter membrane. Crista>>>ATP Production. Number varies with energy. demand of cell. Can self replicate, has ribosomes, has unique DNA, maternal inheritance. Genetic disease such as lebers blindness and cariomyopathy
Cell Membrane Bilipid cell layered membrane. Two layers of fat floating on top of each other.
Hydropholic repels protein
hydrophobic integral channel
40% cell membranes are made of Cholestrol
How do proteins get through cell membrane Integral Channel. Uses H2O to go through due to oil not mixing, Ions pass and Na+, K+, Ca+, Cl, H2O. Peripheral receptor float on surface, Inherited, carb on protein do immune recogniton
Membrane Transport Mechanisims of Cells A)Passive? No ATP is needed. ie.
Diffusion Molecules moving from high to a lower concentration until equilibrium is reached. ie. spray airfreshner
3 types of passive transport? simples diffusion, osmosis, and faciliated diffusion
Diffusion Rate Moving down or from high to low concentraion gradient. ie. oxygen diffusion>> pushes right down lungs, 2) membrane permeability 3)Surface area 4)temperature (hot faster)
Cell Membrane and lipid compounds with diffusion that diffuse fast Alcohol, nicotine patch, solvents(arthritis D6), cocaine, steroids, anasthetics
