CHEMISTRY – define[a]WHAT IS THE STUDY OF ATOMS AND MOLECULES.

[q]

ATOM – define[a]the fundamental unit of matter.

[q]

Protons – define[a]the structures located in the nucleus that have mass and a positive charge (1+)

[q]

Neutron – define[a] structures located in the nucleus that have mass and no charge.

[q]

Electron – define[a]structures that have very small mass, a negative charge (-1) and move around the nucleus in orbitals. Interaction between these and various atoms is responsible for most chemical reactions.

[q]

ATOMIC NUMBER – define[a] the number of protons in a given atom

[q]

ELEMENT – define[a] substance composed of one kind of atom.

[q]

Na is the symbol for which element?[a] sodium.

[q]

K is the symbol for which element?[a] potassium.

[q]

P is the symbol for which element?[a] phosphorus.

[q]

Cl is the symbol for which element?[a] chlorine.

[q]

IONS – define[a] the charged particles formed when atoms gain or lose electrons.

[q]

MOLECULE – define[a]a combination of two or more atoms.

[q]

COMPOUND – define[a] a combination of two or more different kinds of atoms.

[q]

IONIC BONDS – define[a]A type of bond formed when ions that are joined together exchange electrons.

[q]

COVALENT BONDS – define[a]A type of bond formed when two or more atoms share pairs of electrons.

[q]

SYNTHESIS REACTIONS–ANABOLIC REACTIONS – define[a]These reactions involve the formation of large molecules from smaller molecules. (REQUIRE energy)

[q]

DECOMPOSTION REACTIONS–CATABOLIC REACTIONS – define[a]These reactions involve the breakdown of larger molecules into smaller molecules. (RELEASE energy)

[q]

SALT decomposes into what?[a]This compound breaks down into electrolytes (NA+ and Cl-) when dissolved in water.

[q]

ACIDS decomposes into what?[a]THESE SUBSTANCES BREAK DOWN TO RELEASE HYDROGEN IONS (H+) and anions IN WATER.

[q]

BASES decomposes into what[a]THESE SUBSTANCES BREAK DOWN TO RELEASE HYDROXYL IONS (OH-) and cations IN WATER.

[q]

What is the pH of blood?[a] 7.35-7.45 range. (fall out of this range and you will die in a few minutes)

[q]

BUFFERS – function[a]This substance can bind any excess H+ or OH- ions introduced to a system and moderate pH. In practice your body neutralizes a strong acid with a weak base and visa versa.

[q]

MIXTURE – define[a] A COMBINATION OF TWO OR MORE DIFFERENT COMPOUNDS.

[q]

SOLUTIONS – define[a]A a combination of a solvent (like water) and a solute (like salt) that stays evenly mixed.

[q]

COLLOIDS – define[a]This mixture displays different characteristics depending upon the amount of heat in the system. (acts like jello)

[q]

SUSPENSION – define[a]This mixture will allow particles to eventually settle out.(like oil and vinegar dressing)

[q]

CARBOHYDRATES – function[a]These compounds are the the major source of fuel for the body.

[q]

MONOSACCHARIDES – list[a] GLUCOSE, FRUCTOSE, and GALACTOSE.

[q]

Disaccharides – list[a] ARE SUCROSE, MALTOSE AND LACTOSE.

[q]

POLYSACCHARIDES – list[a]STARCH AND GLYCOGEN.

[q]

PHOSPHOLIPIDS – function[a] They make up 2/3 of the cell membrane.

[q]

LIPIDS – list[a] TRIGLYCERIDES, PHOSPHOLIPIDS, STEROIDS.

[q]

Triglycerides – function[a] These compounds provides long term energy, insulation and padding.

[q]

STEROIDS – define[a] cholesterol based hormones, like estrogen and testosterone.

[q]

PROTEINS – define[a]These molecules are composed of amino acids and form the structure of the body.

[q]

Structural proteins – list[a] Collagen Keratin Actin and Myosin

[q]

Functional proteins – list[a]enzymes Antibodies Hormones Hemoglobin Actin and Myosin

[q]

ENZYMES – function[a]These are CATALYSTS and speed up chemical reactions.

[q]
