Respiration  Cellular respiration is the process of oxidizing food molecules‚ like glucose‚ to carbon dioxide and water. C6H12O6 + 6O2 + 6H2O → 12H2O + 6 CO2 The energy released is trapped in the form of ATP for use by all the energy-consuming activities of the cell. The process occurs in two phases: glycolysis‚ the breakdown of glucose to pyruvic acid the complete oxidation of pyruvic acid to carbon dioxide and water In eukaryotes‚ glycolysis occurs in the cytosol.

on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of Hydrogen and Oxygen. This HHO GAS is then

Water is a chemical compound with the chemical formula H2O. A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at standard ambient temperature and pressure‚ but it often co-exists on Earth with its solid state‚ ice‚ and gaseous state (water vapor or steam). Water also exists in a liquid crystal state near hydrophilic surfaces. Water is considered a purifier in most religions. Major faiths that incorporate ritual washing (ablution) include Christianity

Atoms‚ Molecules and Elements Melissa DuBois Chem 110 September 16‚ 2013 Earl Steven Gurley Atoms‚ Molecules and Elements Atoms are the smallest unit of matter and a group of atoms can form chemical bonds in order to form a molecule. Molecules are groups of two or more atoms that have bound together and are the makings of matter. Elements are a substance that has only one type of atom that make up that element. First we can learn about how halogens and alkali metals are extremely reactive‚ where

In chapter 11‚ we learned about DNA and Genes (11.1DNA: The Molecule of Heredity; 11.2From DNA to Protein; 11.3Genetic changes). DNA (deoxyribonucleic acid)‚ which is in a shape called a double helix‚ developed its name from the simple sugar in DNA (deoxyribose). The phosphate group is composed of one atom of phosphorus surrounded by four oxygen atoms. A nitrogen base is a carbon ring structure that contains one or more atoms of nitrogen. Next to cover is DNA replication in which enzyme breaks

Atoms‚ Molecules‚ and Elements Dmitri Ivanovich Mendeleev (1834-1907) was a Russian chemist famous for his formulation of classification of elements‚ or what is now called the Periodic Table of Elements (2011). On 6 March 1869‚ Mendeleev made a formal presentation to the Russian Chemical Society‚ titled “The Dependence between the Properties of the Atomic Weights of the Elements”‚ which described elements

productive cell infection may be controlled at the membrane level‚ requiring the interaction of a specific cellular receptor with the virus envelope‚ as demonstrated recently for Epstein–Barr virus (EBV)1. Therefore‚ we have investigated whether the T4 molecule itself is related to the receptor for LAV. We report here that preincubation of T4+ lymphocytes with three individual monoclonal antibodies directed at the T4 glycoprotein blocked cell infection by LAV. This blocking effect was specific‚ as other

Ch.2 Essential chemistry for Biology 1. Water is precious to life because living organisms use water as the medium (solvent) for chemical reactions necessary to sustain life. Water also helps maintain temperatures. Droughts are disastrous because they can wipe out crops‚ which in turn cause famine. 2. MATTER: Composed of chemical elements‚ occupies space and has mass (ex: solid‚ liquid‚ and gas states.) CHEMICAL ELEMENTS: substance that cannot be broken down into other substances by chemical reactions
