Transcript of Elements and Compounds

Key Terms: Element, compound, Carbohydrate
Lipid, Protein, Amino Acids, DNA. Elements and Compounds pg.74 Water makes up 2/3 of your body. The purpose of water is twofold.
1. Water helps to dissolve chemicals that cells need
2. It helps to keep the cells shape and size Air and Water

Air is a mixture of gases mainly consisting of Oxygen, Nitrogen and Carbon Dioxide Definition: An element is a substance that cannot be broken down into a simpler substance.The smallest unit of an element is an ATOM.

Element = One kind of Atom, for example Hydrogen. Definition: A compound is when two or more elements combine chemically. The smallest unit of a compount is a molecule.

Compound = Two or more elements, for example Water Organic
Contains Carbon VS Inorganic
Does Not contain Carbon
ex. Water, Salt Notes:
Molecules are always moving, they bump into one another and move so as to evenly distribute The Cell and it's Environment:

Diffusion:- Small molecules move across the cell membrane, from an area of high concentration to a low concentration

Osmosis:- Specifically the diffusion of Water molecules. Investigation:- pg.76
Dropper, iodine, Soda Crackers, Bread and Granulated Sugar Proteins - Lipids - Amino Acids Lipids(Organic):
Stores energy
Olive Oil
Potatoes Proteins:
Examples include enzymes that can speed up and/or slow down chemical reactions. For example, Saliva is an enzyme that breaks down food in the mouth.
Helps with cell structure to build /repair/ stimulate growth in cells
Forms part of the cell membrane
Makes up many Organelles Examples of Proteins
Spiders web
finger nails Amino Acids (Carry out instructions for life):
Long molecules such as Oxygen, Hydrogen, Nitrogen and sometimes Phosphorous
The amino acids contain instructions including DNA and RNA DNA
Genetic material found in Chromatin in the Nucleus RNA
Responsible for the production of proteins found in the cytoplasm and Nucleus
