"Cholesterol is bad for you" - do you agree with this statement or not? - -Do not agree. Cholesterol is vital in maintaining the plasma membrane, however high amounts of low density lipoprotein cholesterol can cause plaque buildup in arteries and may lead to a myocardial infarction or ischemic stroke. High density lipoproteins are good cholesterol, they transport cholesterol decreasing the chance of atheroscherotic plaque buildup. Are polysaccharides soluble or not? - -NOT soluble in water due to size and polymeric character compare the 2 classes of proteins - -Fibrous proteins: extended/strand-like, insoluble in water Globular proteins: compact/ball-like, soluble in water Define anatomy - -the study of the parts of the body and how they relate to each other define anitcodon - -3-base sequence on tRNA define codon - -3-base sequence in mRNA define electrons - -negatively charged particles, located in orbital around nucleus define homeostasis - -maintenance of a relatively stable internal conditions even though the external environment it changing define hyperplasia - -Growth by increase in cell number via mitosis define hypertrophy - -Growth by increase in cell size define neoplasia - -uncontrolled increase in cell quantity define neutrons - -neutrally charged particles in nucleus define physiology - -the study of the function of the body's parts define protons - -positive charged particles in nucleus define tonicicity - -movement of water in and out of cells, can change the tone or shape of cells define triplet - -3-base sequence in DNA describe acids - -low pH, substances that release hydrogen ions (H+)=protons, also known as "proton donors" describe anaphase - -daughter chromosomes serparate to opposite poles describe bases - -high pH, substances that accept H+, also known as "proton acceptors" describe carbohydrates - -contains sugar and starches, provides body with quick energy describe cytokinesis - -Cytoplasmic division Describe euchromatin - -DNA extended, unravelled from histone proteins, active form of chromatin describe facilitated diffusion - -polar/hydrophilic substances are "ferried" across the lipid bilayer of the plasma membrane by transporters (carrier proteins) describe filtration - -Movement of solution from area of higher pressure to area of lower pressure; down a pressure gradient. Describe heterochromatin - -DNA attached to histone proteins, hence DNA is coiled, inactive form of chromatin describe intermediate filaments - -medium diameter, cables of tough, insoluble fibrous protien fibers that resist tension placed on cells describe interphase G1 phase - -longest phase;
