William Perez Cell Biology 2440 Lab on protein Myosin Proteins are chains of amino acids that perform the most important functions in living organism. Every protein will contain an amino group‚ carboxyl group‚ a different R group and an alpha carbon with two hydrogens. There are nine types of functions proteins can have‚ enzymes‚ motor‚ receptor‚ structural‚ storage‚ transport‚ signaling‚ and special purpose proteins(antibodies). There are four levels of protein structure‚ primary‚ secondary

nutrients that collectively aid in photosynthesis‚ growth‚ formation of proteins‚ and overall quality of the plants. Not having these essential nutrients may result in various diseases‚ leaf discoloration‚ and very limited growth. In our experiment we decided to test how exposure to sunlight (or lack thereof)‚ and the amount of nutrients available to plants affect seed germination as well as overall plant growth. We did this by exposing some plants to light while others not‚ and by applying the synthetic fertilizer

The purpose of antimicrobial drugs is either to inhibit virus replication‚ without harming host tissues or to interrupt the cell processes or structures of bacteria‚ fungi‚ and protozoa. This lab has brought great interest to me because this is the way physicians’ control/treat infectious disease within our bodies. In this lab‚ chemotherapeutic agents were evaluated by the disk-diffusion method. Chemotherapeutic agents are placed on the surface of a Petri plate containing

BIOLOGY LAB REPORT (UNIT 7: ENZYMES) GENERAL Enzymes are protein that acts as catalyst‚ lowering the activation energy need for reactions to progress in cells. The reaction can still occur without the presence of the enzyme‚ but at a much slower rate. The activation energy is the minimum amount of energy need for a chemical reaction to occur‚ yielding from a given set of reactants. In enzymatic reactions‚ we have substrates which are reactants of reaction bound to an enzyme. While an active site

Oscillators & Oscilloscope Morgan Dennis @02514008 Partners: Brittany Smith‚ Michelle Trang‚ James Anderson‚ Madison Shaw OBJECTIVE: We are going to study the features and operation of the oscilloscope. We will use the instrument to measure the frequency and amplitude for various sources. Ultimately‚ the oscilloscope will display the Lissajous figures. APPARATUS: The major apparatus used include; Oscilloscope‚ two audio oscillators‚ battery and connectors. THEORY: The oscilloscope

Effect of enzyme concentration on rate of reaction Research question: is there a relationship between catalase concentration and the rate of reaction? Hypotheses: if the enzyme concentration is increased then the rate of reaction will increase. If the enzyme concentration is decreased then the rate of reaction will decrease. Controlled: temperature Independent: % catalyze concentration ( Dependent: rate of reaction (mm/s) Materials: Mortar and pestle Graduated cylinder Distilled

Potato Osmosis Biology SL - ATh INVESTIGATION “Potato Osmosis” INTRODUCTION Osmosis is a process that occurs at a cellular level that entails the spontaneous net movement of water through a semi-permeable membrane from a region of low solute concentration to an area of high solute concentration in order to equalize the level of water in each region. Involved in this process are hypotonic‚ hypertonic and isotonic solutions. A hypotonic solution is one with a lower osmotic pressure‚ indicating

Jem and Scout Finch are brother and sister. Scout is six and Jem is ten. They live with their dad Atticus and a housekeeper named Calpurnia. Over the summer they meet a boy named Dill‚ who wants to marry Scout. Jem tells Dill about a scary house that the Radley family lives in. Throughout the summer they try to make Boo Radley come out. Jem and Scout start to find things in a tree near the Radley’s house. They find gum‚ pennies and soap dolls. Scout begins to become close friends with a
