Tertiary structure

Sofya Tkachman AP Biology, A2 Dr. Lau 15 September, 2015 Enzyme Catalysis I. Purpose Measure the activity of catalase in potato extract using several different methods. II. Procedure a) Cut 20 small circles from a large filter paper disk using a hole puncher. Clean and dry several medicine cups and pour hydrogen peroxide into one. Put the catalase enzyme, previously prepared by blending a potato, into another medicine cup. Make a 1/8 dilution of the catalase by adding chilled distilled water.…

Proteins are a type of macromolecule and have four structures, primary, secondary, tertiary and quaternary. A primary structure of a protein is made up of monomers of amino acids, and is a simple sequence of amino acids joined together by polypeptide bonds. The secondary structure of proteins, is a sequence of amino acids with the polypeptide bonds interacting with one another. The tertiary structure, involves both interactions between amino acid bonds and polypeptide links…

3.1.1.1 The first industry The Great Leap Forward began in agriculture. In 1957, the central committee of the Chinese Communist Party passed the development plan of agriculture from 1956 to 1967. The construction of the water conservancy project, increase in agricultural yields, transformation of landscapes, collectivization, and elimination of four pests were advocated. Numerous dams, water drainage systems, and canals were built. Unfortunately, the majority of them were constructed on the…

ABSTRACT: Enzymes are catalysts, speeding up of chemical reactions, of biological systems by lowering the activation energy (Transitioned from the AP Biology Lab Manual). In addition, in order to determine the rate of an enzymatic reaction, one must measure a change in the amount of at least one specific substrate or product over time. We were curious about determining the effects of pH and heat on enzymatic activity because these are factors that usually affect the shape of an enzyme. We…

cultures and understood differently. In the ecology and structure of the Nuer, they are different then the other places. The Nuer believe that they are a cow husbandry, and they believe they are not horticulture like the other different places around the world. In the book, they also say, “I am person of such and such a cieng”, and I interpreted as that I am a person and this…

process has always been something of a mystery to medical science because the body's regeneration normally manages to cure most injuries to human tissue. This paper examines healing process of tendon injuries. In the first part of the paper, the structure of tendons will be examined, then the second part will cover tendon injury mechanisms and finally the third part will cover the main phases of the healing process and possible ways to optimize the…

Describe the chemical structure and function of DNA DNA is a fundamental molecule responsible for the growth and maintenance of the human body. Since the discovery of DNA and its double helix structure though the Watson-Crick Model, there has been a significant increase in the understanding of human disease and development of effective treatment. DNA’s specific chemical structure allows it to carry out its function which therefore maintains our survival. Deoxyribonucleic acid is a…

The dopamine active transporter is a 12 integral membrane-spanning protein that moves the neurotransmitter dopamine out of the synapse back into cytosol terminating therefore the signal of the neurotransmitter. The dopamine reuptake via DAT is the primary mechanism from which dopamine is cleared from synapses. Its function requires the binding and cotransport of two Na+ ions and one Cl− ion with the dopamine substrate. The driving force for DAT-mediated dopamine reuptake is the ion concentration…

environment: The Depositional environment throughout the Cooper Basin formations is wholly non-marine, with the Patchawarra formation being a fluvial/deltaic depositional environment, with point-bar sandstones the most common reservoir type. Trap structures: Traps in the Cooper Basin are recognised as being structural e.g Anticlines, Stratigraphic e.g. facies change or a combination of these. Most traps in the Patchawarra formation are combination traps and lie somewhere between purely…

elaborate on the role of aqueous humor and vitreous humor in maintaining the pressure of the globe, the structures related to the humor, functions of the humors, origin and also pathology related to them. PHYSIOLOGY OF THE AQUEOUS HUMOR The aqueous humour is a transparent fluid similar to plasma, but containing low protein concentrations. It is secreted from the ciliary epithelium (a structure supporting the lens). It is located in the anterior and posterior chambers of the eye, the space…
