WHAT IS AN ION?
AN ELECTRICALLY CHARGED ATOM OR MOLECULE.
WHAT ARE THREE CHEMICAL REACTIONS?
1. SYNTHESIS - TWO ORE MORE ATOMS BOND TO FORM A MORE COMPLEX STRUCTURE. EX. A+B=AB

2. DECOMPOSITION - Bonds break so simpler molecules, atoms, or Ions form. Ex. AB=A+B

3. EXCHANGE REACTION - 2different types of molecule exchanging positions. Ex. AB+CD=AD + CB
1. CELLS CONTAIN INORGANIC SUBSTANCES THAT LACK WHAT CHEMICAL SUBSTANCES?

2. WHAT 4 INORGANIC SUBSTANCES ARE IN CELLS?
1. Carbon and Hydrogen.

2. WATER - needed for metabolic reactions, transports heat, absorber

OXYGEN - necessary for cellular respiration.

CARBON DIOXIDE - carbon containing compound produced as a waste product.

SALTS (electrolyte) Provides sodium, potassium, calcium, magnesium, phosphates. These Ions are important for metabolic processes, transport substances in and out of cells, muscle contractions, nerve impulses conductions.
WHAT ARE BASES?
Electrolytes that releases ions that bond with hydrogen in water.
WHAT ARE ACIDS?
Electrolytes that releases hydrogen Ions in water.
1. WHAT IS A CARBOYHYDRATE?

2. WHAT ARE THE TWO TYPES OF CARBOHYDRATES?

3. NAME 2 TYPES OF COMPLEX CARBOHYDRATES?
1. Molecules consisting of Carbon, Hydrogen, and Oxygen.
1b. Short chains are sugars (gluclose, fructose, galactose)

2. DISACCHAIDES - 2 sugar building blocks (sucrose (table sugar) Lactose (milk)

Polysaccharides - many sugars.
WHAT IS AN ELECTROLYTE?
Substances that release Ions (electrically charged Atoms/molecules) in water?
