Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

unable to cleave the signal sequence amino acid. B. Band B is the cleavage of the signal sequence by the signal peptidase. The cleavage of the polypeptide weighs less then when the protein was attached to the signal sequence and before it grows in the ER lumen. This is evident from the diagram‚ since lighter proteins move father down the gel than do heavier ones. Given the length

Lab 4 Quiz 1. Enzymes and what is their function? a. Enzyme: biological catalysts that regulate chemical reactions that occur in cells. Responsible for things such as converting food to energy‚ replace old damaged tissues‚ disposal of cellular waste products. Are responsible for lowering the activation energy. 2. Most enzymes are proteins with three-dimensional shapes determined by their amino acid sequence. 3. Substrate – is a reactant molecule that binds to the highly specific active site

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

Standard Solution (Part A and B) ABSTRACT The purpose of this experiment is to prepare a standard solution of potassium hydrogen phthalate and use titration to perform an acid/base reaction between the potassium hydrogen phthalate and sodium hydroxide to standardize approximately 0.10 M sodium hydroxide solution. To prepare the Potassium Hydrogen phthalate‚ a 2.00 grams of KHP was measured to an accurate measurement of 1.980 grams. A total of 100 mL of water was mixed with the KHP solution

Biochemistry is the chemistry of biological systems. The practical component of biochemistry is aimed at developing your interest in and understanding modern biochemical and molecular biological experimentation. The techniques learnt in the biochemistry lab will be applicable to all life sciences. THE OBJECTIVES OF THE BIOCHEMISTRY LABORATORY INCLUDE: (1) Learning the theory behind the techniques and biochemical pathways (2) Learning the physical skills and techniques of modern experimental biochemistry

Insertion and amplification of EGFP protein into pET41a(+) Plasmid Introduction The overall purpose of the experiments conducted is to test the creation of recombinant plasmid using recombinant DNA technology. The research of recombinant DNA began with the use of E.Coli (Escherichia coli)‚ a common bacteria found in the intestines of warm-blooded or- ganisms (5). Scientists worked together and generated a way‚ from cloning and using recombi- nant research‚ to achieve recombinant DNA

major biomolecules‚ they are Carbohydrates‚ Lipids‚ Proteins‚ and Nucleic Acids and they all have different functions and characteristics to classify an organism. Carbohydrates are the most important source of energy for your body‚ this is mainly sugar. Lipids are molecules that contain hydrocarbons and make up the structure and function of living cells. Nucleic acids is an organic system present in living cells‚ especially in DNA or RNA. A protein is very essential for the living body its is made

Protein Article Research John Doe SCI 241 May 17‚ 2012 Jane Doe Protein Article Research This class has been very informative during the past few weeks. We have learned how to count calories‚ read nutrition labels‚ use a tracker to monitor our daily intake‚ carbohydrates‚ and learned about proteins and their effects. According to the readings in the text and the article proteins are the building blocks in the body. I learned that protein is found in all tissues‚ cells and organs of the body

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle
