Oxygen - A nonmetallic element constituting 21 percent of the atmosphere by volume that occurs as a diatomic gas, O2, and in many compounds such as water and iron ore. It combines with most elements, is essential for plant and animal respiration, and is required for nearly all combustion. Atomic number 8; atomic weight 15.9994; melting point -218.4°C; boiling point -183.0°C; gas density at 0°C 1.429 grams per liter; valence 2. Failures in the oxygen cycle within the hydrosphere (the combined mass

derives its name from this island. Malta provided an environment relatively free of outside influences, allowing the Maltese to retain their unique characteristics.

Renaissance paintings show that the Maltese were popular in Italy. They were known in Britain in the 16th century and may have been brought there by invading Romans or returning Crusaders.

larger, or still partially undigested, fragments of protein that may have been absorbed by the small intestine. Pepsin is prepared commercially from swine stomachs. Crude pepsin is used in the leather industry to remove hair and residual tissue from animal hides prior to their being tanned. It is also used in the recovery of silver from discarded photographic films by digesting the gelatin layer that holds the silver compound. * Worthington Biochemical Corporation - Pepsin Pepsin is the principal

“Between stimulus and response there is a space. In that space lies our freedom and power to choose our response. In our response lies our growth and freedom.” Viktor Emil Frankl, M.D., Ph.D (Man's Search for Meaning; 1946 ) Everyone of us, Human or animal alike, have been living in this world since the primordial time.

The source of his humanity is in his ability to feel the things he did when he was human. He

biochemistry or cell biology course. Proteins are the major components of living organisms and perform a wide range of essential functions in cells. While DNA is the information molecule, it is proteins that do the work of all cells - microbial, plant, animal. Proteins regulate metabolic activity, catalyze biochemical reactions and maintain structural integrity of cells and organisms. Proteins can be classified in a variety of ways, including their biological function (Table 2.1). Table 2.1 Classification

many chemicals within the body, are not consumed in the reaction, and so are able to catalyze many reactions in their life cycle. Enzymes are able to reduce the activation energy of the reaction; the energy required to break bonds between the reactants, and form new bonds in the products, which allows more product to be formed. (Marieb and Hoehn, 2010, pp.51-53). Enzyme activity is affected by changes in the pH of their solution. For each individual enzyme, there is a corresponding pH at which
