Term
Diffusion
Definition

passive transport of molecules from areas of high concentration to areas of lower concentration until concentration is equal (in equilibrum)

 

Example: Tea in a tea bag will diffuse equally thru a pitcher of un-stirred cold water eventually

Term
Inorganic Compound
Definition
  1. Not Organic
  2. Do not cotain both "H" Hydrogen & "C" Carbon in their structure
  3. Naturally existing compounds that can be formed by just the forces of nature

Examples: Water (H2O) Carbon Dioxide(CO2)

Term
Universal Solvent
Definition

WATER

 

More "things" (solutes) dissolve in water than any other substance(solvent) on earth... not all just more things dissolve into water to form a solution

Water

 

Examples: Salt (salt water) sugar & tea(sweet tea)

Term
Enzyme
Definition
  1. Type of protein that regulates almost all chemical reactions in living organisms
  2. Names frequently end in "-ase"

Example: If you are Lactose (milk sugar) intolerent your body has lost the ability to produce and use Lactase

Term
Passive Transport
Definition

Movement of substances through a cell membrane without the use of cellular energy

  • diffusion, osmosis, faciliated diffusion
Term
Photo-Synthesis
Definition

LIGHT / TO CONSTRUCT USEING

 

Food making process by which plants and other producers use light energy to produce glucose and oxygen from carbon-dioxide and water

 

(6) CO2 + (6) H2O = C6H1206 + (6) O2

Term
OSMOSIS
Definition

The diffusion of water through a cell membrane

Term
Organic Compounds
Definition
  1. Compounds that ALWAYS contain both "C" Carbon & "H" Hydrogen in their structure
  2. MOST do not naturally occur in nature.
  • Carbohydrates
  • Lipids
  • Proteins
  • Nucleic Acids
Term
Fermentation
Definition

Process by which some oxygen lacking cells and some one celled organisms release amounts of energy from glucose molecules and produce wastes such as alcohol, carbon-dioxide, and lactic acids

  • Anaerobic respiration (without oxygen)
Term
Equilibrium
Definition

When molecules of one substance (usually a solute) are spread evenly throughout another substance (usually a solvent)... Example a solution of salt & water

  • because materials are in a constant state of movement "Equilibrium" is also when the flow of a material going one way thru a cell membrane is equal to the flow of the same material flowing the other way
Term

Mixture

Definition

A combination of substances in which the individual substances do not change or combine chemically but instead retain their own chemical properties; can be solids, liquids, gases or a combination of them

 

examples; bread, cake, soil, dirty water, vinager&oil, the air we breath.

Term
Exocytosis
Definition

 EXO - exit/out   &   CYTOSIS use energy to push

 

Process by which vesicles (packaged in the Golgi Complex) release their contents outside the cell

Term
Respiration
Definition

Series of chemical reaction (regulated by enzymes) used to release energy stored in food molecules

  • "Potential(food) energy" is converted to "Kinetic Energy" by enzymes as catalysts requireing low "activation energy"
  • Aerobic (with O2) & Anaerobic (without O2)
Term
Endocytosis
Definition

ENDO -enter/bring in   CYTOSIS- push using energy

 

Process by which a cell takes in a substance by surrounding it with the cell membrane.

Term
Metabolism
Definition

The total of all the chemical reactions within an organism

Term
Active Transport
Definition
Energy-requiring process in which transport proteins bind with particles and move them through a cell membrane
Term
Solution
Definition

A combination of substances (solute & solvent) in which the individual substances do combine physically but retain their own chemical properties; can be solids, liquids, gases or a combination of them

 

examples; saltwater,

Term
Compound
Definition

2 or more elements that combine physically and chemically that have new chemical properties

1) Hydrogen gas & Oxygen gas are both explosive ... combined = water a liquid that puts out fire.

2) Sodium a poisonous metal + Cloride a poisonous gas ... combined are a crystaline solid table salt (NaCl)

Term
