Sept 27‚ 2010 Chapter 4 * With four valence electrons‚ carbon can form four covalent bonds with a variety of atoms * This tetra valence makes large‚ complex molecules possible * Fundamental groups: Alkanes and Alkenes * The electron configuration of carbon gives it covalent compatibility with many different elements * The valences of carbon and its most frequent partners (hydrogen‚ oxygen‚ and nitrogen) are the “building code” that governs the architecture of living

Answer the following in at least 100 words: 1. Describe the structure of DNA. ➢ DNA is a nucleic acid‚ which consist of long chains (polymers) of chemical units (monomers) called nucleotide. A molecule of DNA contains two polynucleotides‚ each a chain of nucleotides. Each nucleotide consists of a nitrogenous base‚ a sugar‚ and a phosphate group. Each DNA strand serves as a mold‚ or template‚ to guide reproduction of the other strand. There are four different types of nucleotides found in DNA

Many girls all over the world wear nail polishes to make their nails look pretty and shiny. Nail art is a lot of time consuming activity because it is hard for the polish to be applied on the nail evenly‚ also it takes a lot of time to dry. While the nail polish is drying‚ girls cannot do anything but just wait or do something and get their nails ruined. It is also extremely hard to keep them in perfect condition. After two to three days from applying‚ the polish starts to get chipped. However‚ after

pH can range from 1-14‚ 7 being neutral‚ 7-1 being more and more acidic towards 1‚ and 8-14 being more and more basic towards 14. The product that was measuring to determine the enzyme’s performance was glucose‚ a monomer or small molecule‚ of the polymers‚ consisting of bound monomers‚ lactose and maltose. We hypothesized that lower temperatures would cause the enzyme to slow down and at higher temperatures it would unravel or go through

Hydrolysis Report Bile Esculin Hydrolysis‚ Starch Hydrolysis‚ UreaHydrolysis‚ Casein Hydrolysis Hydrolysis Report Introduction Hydrolysis is a chemical reaction that uses water to split complex molecules. The water molecule H2O is split in the mechanism of hydrolysis‚ hydrogen cations and hydroxide anions. When the enzyme catalyzes its reaction inside the cell‚ it is referred to as intracellular hydrolases. When the enzymes secreted from the organism to catalyze reactions outside the cell‚ it
