Chemistry Part 1
Atoms
Make up matter
Molecules
Atoms of the element bonded together
(Example 02)
Suspensions part 1
Gas or liquid has another substance evenly spread throughout it
Inorganic compounds
Does not contain carbon
Proteins
made up of amino acids, make up many structures like muscles, make up enzymes- regulate all chemical reactions in cell
Electrons
Found outside nucleus have negative charge
Compounds
Made up two or more different elements that combine chemically
(i.e H20-water;C02;C0
Suspensions part 2
Substances can sink to the bottom
Water
-Living things are made of more than 50% Water
-Inorganic compound
-Needed for chemical reactions to occur
-Used to transport materials though organisms
Enzymes
Regulate all chemicals reactions in the cell
Protons
Found in nucleus have positive
Mixture
Made of substances that combine physically
Blood part 1
-Is a suspension
-Red,white blood cells and platelets do not evenly
Organic Compounds
Contains carbon, associated with living or once living things
Nucleic Acids
These store coded information for cells DNA- deoxribonucletic acids.
Neutrons
Found in nucleus have no charge
Mixtures
Can be liquids, gases, solids or combinations of two
(Examples sand and baking soda)
Blood part 2
-Stays together in body b/c hearts keeps blood flowing and blood cells suspended
Carbohydrates
Supply energy for cell processes
DNA
direct activities of the cell
Element
Made up one type of atom
Solutions
Two or more substances are mixed evenly
(Examples saline solution- salt and water)
Examples of suspensions
Oil and H20;fine sand and H20
Lipids
Fat and oils, do not mix with water, release a latger amount of energy than carbohydrates, harder to break down, found in cell membrane selectively permeable b/c, fats and oils do not mix with water
