Related Categories: Science biology cell biology. enzymes - the word enzyme was first used in 1878 and comes from two Greek words meaning, "in yeast." All enzymes are globular proteins. . Enzymes control body chemistry. . The enzymes of line the human body work by means of surface catalysis (m. . That is the surface of the enzyme enables other molecules to react in a manner they would not without the surface of the enzyme present. . The enzyme being the catalyst is not changed in any manner from the action of the protein. . The human body contains only a small quantity of enzymes but even this small quantity is sufficient. .
Some parts of the human body contain more than other parts but it exists is some amount in all parts of the body and it is vital for life to exist. . There is no living organism that does not contain protein. . Viruses for example contain a complicated type of protein called nucleoprotein. . Nucleoprotein contains a type of substance called nucleic acid in association with the protein. . When proteins are exposed to an acid the protein breaks apart into smaller molecules. . These smaller molecules are called amino-acids. . Millions of different proteins can be formed from the combinations write of different amino-acid molecules. . Some common proteins are: keratin, fibroin, collagen, and the important and numerous globular proteins.
All life forms are composed of basic chemical elements. . Atomic elements prefer to exist as molecules. . Earth life thrives on water. . The human body for example is about 3/5ths water. . Life is built up from some very common materials. . There is one biography substance though that is more complicated and vital to life. . a dutch biochemist, named Mulder, first used the word "protein" in 1838. . he got the word form a greek word meaning "holding first place." A protein molecule is quite large compared to fat or sugar molecules. . Although proteins are complicated they consist the elements of carbon, hydrogen, oxygen, nitrogen and sulphur. .

Org biology Online - information in the life sciences in the form of tutorials, references, an online dictionary of biology terms and a biology forum. The scientific method - the scientific method consists of stating a problem then; (1) make observations, (2) formulate a hypothesis, (3) design an experiment, collect and interpret the data, consult prior knowledge, and (4) reach conclusions. A good experiment has a large sample; it is controlled so that only one variable is assessed, it is placebo controlled, and it is conducted in a double blind manner. . Scientific discovery is not always as well planned as the scientific method may seem to suggest. . Sometimes new knowledge comes simply from being in the right place at the right time or from being particularly aware of the unusual. .
The opposite of the scientific method (and its organized planning) is discovery by "accident". A hypothesis is a guess as to why something happens. Observations lead to questions regarding the event. Why is the sky blue? How does gravity affect falling objects? In attempting to answer a question about the nature of the world, a scientist will form a hypothesis (or a guess) regarding the question's answer. .

by phagocytes)-they flow around their prey (usually a smaller cell) and engulf. Organism that eat other organisms are usually called "consumers". . The amoeba's cell membrane then fuses with itself, trapping the prey in a "food vacuole" where it will be digested.
