Welcome to Dr. Stephens’ Cellular Fun Jeopardy Cellular Endomembrane systems 100 200 300 400 500 600 700 800 900 1000 Mitochondria, A Potpourri Let it in…Kick it Planes, trains and Automobiles of cell Out!! Chloroplasts, &Hodgepodge membranes Membranes Etc. OH MY! Of CELLS!! 100 200 300 400 500 600 700 800 900 1000 100 200 300 400 500 600 700 800 900 1000 100 200 300 400 500 600 700 800 900 1000 100 200 300 400 500 600 700 800 900 1000 100 Part of the endomembrane system that has ribosomes attached What is the Rough E.R. Continue 200 Cells which lack a nuclear membrane and organelles. These are found only in Domains Archaea and Prokarya What is a Prokaryote Continue 300 Cells that have a definite membrane-bound nucleus and organelles. Found in the following kingdoms: Plantae, Animalia, Protista, & Fungae. What is a Eukaryote (eukaryotic) Continue 400 Surrounded by a tonoplast, this organelle is found in mature plant cells and stores organic compounds and inorganic ions for the cell What is a Central Vacuole Continue 500 Membrane enclosed sacs of hydrolytic enzymes used by animal cells to digest macromolecules; acidic environment found within these structures What are Lysosomes Continue 600 The process by which some molecules are allowed to enter a cell while others are not. What is selective permeability Continue 700 These are the functions (name 2) of the smooth E.R. What is lipid production, carbohydrate metabolism, drug detoxification and calcium release Continue 800 Vesicles that bud from the E.R. join the cis face of this organelle; this organelle helps to process and package them where the vesicles are then “pinched” off of the trans face. What is Golgi apparatus Continue 900 In eukaryotes, this organelle makes rRNA and adds it to proteins to make ribosomal subunits, which are passed out of the nucleus to aid in protein formation. What is Nucleolus Continue 1000 Prokaryotes do not have nuclei, but they have “this region” where DNA is concentrated What is the nucleoid Continue 100 The cellular structure that is involved in producing ATP during aerobic respiration What is Mitochondria Continue 200 This organelle contains enzymes that break down fatty acids for energy or detoxify alcohol and poisons; converts H2O2 to water What is a peroxisome Continue 300 This is an example of a type of plastid (and this plastid’s function) What is (e.g.) a chloroplast (contains chlorophyll to help function in photosynthesis Continue 400 All cells have “these” 4 things in common What is a)plasma membrane, b)ribosomes, c)genetic material, d) cytosol, etc. Continue 500 Within the mitochondria’s phospholipid bilayer is a mitochondrial matrix (where respiratory enzymes help in respiration). This matrix is surrounded by these large surface area folds on the inner membrane What are Cristae Continue 600 Mitochondria and chloroplasts contain a small amount of this nucleic acid (that directs sythesis of some of their proteins) What is DNA Continue 700 This organelle is not part of the endomembrane system and can grow larger and increase in number by splitting in two when they reach a certain size What is a Peroxisome Continue 800 Within a chloroplast’s double membrane is a)“this fluid”, b)“these flattened sacs” and c) “many flattened sacs stacked together” What is stroma, thylakoid and grana Continue 900 This endomembrane organelle can be confused with H2O2 decomposers, but this organelle fuses with and digests food vacuoles and aids in autophagy What is Lysosome Continue 1000 Roots and tubers store this colorless plastid (that stores starch) What are Amyloplasts Continue 100 These are the anchors that hold the cilia and flagella in place What are basal bodies Continue 200 This is a lab tool used in the cell fractionation process where denser substances are separated from smaller, less dense substances in a “fast spinning” process What is a centrifuge Continue 300 An endocytosis process where a cell takes in fluid-like material (in an invagination process with the cell membrane) What is pinocytosis Continue 400 These are the organelles that are primarily involved in ion storage What are vacuoles Continue 500 What organelle is expected to be found in abundance in the arm muscles of an Olympic weight lifter What are mitochondria Continue 600 These pump excess water out of the cell, thereby maintaining the appropriate concentration of salts and other molecules. What is a contractile vacuole Continue 700 These are two sites of protein synthesis within a cell What are cytoplasm, mitochondria, and/or E.R. Continue 800 Chloroplasts and mitochondria contain prokaryote-like ribosomes, so they are thought to have evolved from “this Kingdom”. What is Monera (the bacteria) Continue 900 This is the primary difference when comparing mitochondrial and chloroplast membranes Mitochodria is a bilayer…chloroplast is a “trilayer” (2 outer membranes and thylakoid “membranous system”). Continue 1000 Cilia and flagella move due to their interaction of the cytoskeleton with these types of proteins What are Motor Proteins Continue 100 This is the name of the currently accepted model describing cellular membranes What is the Fluid Mosaic Model Continue 200 In 2003, this award was rewarded to Agre and MacKinnon who worked on ion and water transport across the plasma membrane What is the Nobel Prize in Chemistry Continue 300 Getting hungry yet? This membrane model inferred that all membranes were treated equal and that hydrophilic proteins coated both sides of the membrane. What is the DAVSON-DANIELLI sandwich model Continue 400 This “steroid” is a temperature buffer for membranes, as it makes membranes less fluid by restraining movement of phospholipids but it also lowers the membrane solidification temperature. What is cholesterol Continue 500 This “very cool” word describes molecules that have both hydrophilic and hydrophobic regions (and thus lend themselves to make great membranes!) What is “amphipathic” Continue 600 In order for membranes to work properly, they must have the approximate consistency of “this” (give a food example) What is salad oil Continue 700 Glycoproteins and glycolipids are short-branched segments of “these” that are covalently bonded to lipids and proteins and play a functional part in the membrane. What are carbohydrates Continue 800 This general class of proteins spans the membrane bilayer where the hydrophobic, nonpolar amino acids are near the hydrophobic tails…and the hydrophilic portions are found on the outside and inside of the membrane What are integral proteins Continue 900 “These proteins” serve the function of catalyst of chemical reactions, as their active site is exposed to certain substances What is an enzymatic protein Continue 1000 Membrane proteins of adjacent cells help to hook the cells together …an example of these junctions are ________________ What is gap or tight junctions Continue 100 The tendency for molecules of any substance to spread out evenly into the available space What is diffusion Continue 200 Hydrophilic substances that need to get into and out of the cell do not do well going through the hydrophobic part of the membrane. So they might pass through these hydrophilic channels What are Transport Proteins Continue 300 A type of transport protein that allows specifically for the passage of water What are Aquaporins Continue 400 A membrane transport process where energy is not required to move something What is Passive Transport Continue 500 Substances diffuse down their _____________________________, which is diffusing from an area of high to low concentrations What is a Concentration Gradient Continue 600 If I transfer my animal cell to this type of solution (related to solute concentration) , the cell will likely shrivel up What is hypertonic Continue 700 Paramecium are examples of organisms that have a special adaption called “this” that allows them to control water uptake and exit What is osmoregulation Continue 800 This wilting, and sometimes lethal action occurs to plant cells with walls (and some other types of cells) when submerged into a hypertonic environment What is plasmolysis Continue 900 A generic term referring to a molecule that binds specifically to a receptor site of another molecule What are ligands Continue 1000 A transport protein that generates voltage across a membrane. What is an electrogenic pump Continue
