they serve as fuel and building material. Plants store most of their energy in the form of starch. Starch is a polysaccharide (consisting of several conjoined sugars). Synthesizing starch enables the plant to stockpile surplus glucose‚ and since glucose is a major cellular fuel‚ starch represents stored energy. The sugar can later be withdrawn by hydrolysis‚ which breaks the bonds between monomers. Animals‚ in turn‚ have enzymes that can hydrolyze plant starch‚ making glucose available as a nutrient

Writing about literature - an essay THE CAN-CAN: WHAT CAN AND WHAT CAN’T? By Huy Phát A popular provocative dance move in the Broadway shows in 1950s has been chosen as the title for this short story “The Can-can” of Vivante about a man having a love affair while his thought was wandering around “somebody doing the can-can”- his wife back home. The can-can therefore does more than just being the title‚ its repeated recurrence in the story recognizes itself as a noteworthy symbol and also contributes

WADING THROUGH THE WASTE: A LOOK INTO THE FAILURE Wading Through the Waste: A look into the failure of American landfills and how plasma gasification can fix it Joshua A. Valdez ITT-Tech Jacksonville‚ Fl GE117 Chambers Abstract America‚ a “throw away” society‚ is facing a tragic consequence of its lifestyle. Even with increased recycling efforts Americans are running out of space to put their trash. With stricter regulations and public policies‚ the number of landfills

The Protein Data Bank Assignment: Glucansucrase After I came to America‚ I have already met my dentist many times. Although I brush my teeth three times a day‚ use floss correctly and meet dentist every year‚ I don’t know why my teeth keep in trouble and get cavities again and again. I really want to figure out why the bacteria from my mouth cannot be removed. When I am finding some protein‚ I found that Glucansucrase which is related on the issue of tooth decay. I think Glucansucrase

G-protein Coupled Receptors (GPCRs) are cell surface proteins that relay extracellular signals to the nucleus. These signals can be in the form of light‚ peptides‚ lipids‚ and sugars. Once activated by a ligand at the outer cell surface‚ GPCRs activate their cognate G-proteins that reside on the inner cell membrane. The activated G-proteins then slide along the inside of the cell membrane to activate a cascade of proteins and enzymes that in turn amplify the original message received by the GPCR

permeability of cell membranes using fresh beetroot Aims In this investigation‚ you will subject fresh‚ washed beetroot discs to different temperatures to investigate the effect of temperature on the permeability of the plasma membrane. Overview The beetroot discs will be placed in distilled water at different temperatures. You will compare the intensity of the beetroot pigment that has leaked out from the cells subjectively and possibly objectively using a colorimeter. You can relate the findings

Report on Receptor Proteins According to Abedon (2012)‚ receptor proteins are intracellular proteins‚ or protein fractions‚ that have a high specific affinity for binding a known stimulus to cellular activity. Receptor proteins may be located at cell surfaces or within the interior of cells. They may detect hormones or instead keep track of what otherwise is going on in cell ’s environment. They may be enzymes or serve to relay the occurrence of signal reception in other ways such as by opening

Protein Article Research Kristen Roberts Immunity is the ability of a body to resist infection or to counter the harmful toxins produced by infecting organisms (Martin‚ Hine 2008). Antibodies and white blood cells are defensive cells and substances‚ these things produce an immune response. If such an encounter such as‚ bacteria‚ viruses‚ fungi and parasites occur can make the macrophages engulf the microorganism and secretes cytokines and chemokines. This attracts immune cells to the infected

A protein is a Biological polymer made up of as different amino acids joined by peptide bonds. A protein is formed by amino acids which are the basic building block of a protein components of an amino acid include a :C-carbon atom‚ H-Hydrogen atom‚ H3N+ - Amino Group‚ COOH- - Carboxyl Group‚ R- this group varies from amino acid to amino acid. There are 20 amino acids‚ each differing in its R group. Two examples are: Glycine‚ its R group being H(Hydrogen) and Phenylalanine its R group being CH2 (Carbon
