Term
Aerobic Respiration
Definition
The process in which cells make ATP by breaking down glucose; requires oxygen.
this happens in the Eukaryote- Matrix, Cristae, Inner and Outer Membranes
Produces ATP for energy.
Term
Cellular Respiration
Definition
C6 H12 O6 + 6O2 = 6CO2 + 6H2O
Term
Facilitated Diffusion
Definition
Passive Transport, involves carrier proteins.
Term
Carrier Proteins
Definition
Protein that transports specific substances across a biological membrane.
Term
Diffusion Across Membrane
Definition
If a molecule is able to pass through a cell membrane, it wil diffuse from an area of higher concentration to an area of lower concentration.
Term
Fermentation
Definition
Process in which cells convert glucose into lactic acid or ethel alcohol, in the absence of oxygen.
HELPS KEEP GLYCOLYSIS GOING;
2 Types.
No ATP produced.
Term
2 major steps to Aerobic Respiration
Definition
The Krebs Cycle and the Electron Transport Chain.
Term
Electron Transport Chain
Definition
Process in which high energy electrons are passed along a series of molecules.
Term
Why do we breathe?
Definition
To get oxygen to the mitochondrion.
Term
Solvent
Definition
liquid in a solution that disolves everything else.
Term
Equilibrium
Definition
When the concentration of the molecules of a substance is the same throughout a space. (molecules are still in random motion)
Term
Solute
Definition
Gets disoved by the solvent.
Term
endocytosis
Definition
the process by which cells ingest external fluid, marcromolecules, and large particles, including other cells.
Term
isotonic
Definition
A solution whose solute concentration equals that inside the cell.
Term
hypotonic
Definition
A solution whose solute concentration is lower then that inside a cell.
Term
hypertonic
Definition
A solution whose solute concentrarion is higher then that inside a cell.
Term
active transport
Definition
From a lower concentration gradient to a higher concentration gradient
Term
exocytosis
Definition
the process by which a cell expells its contents into the cell's external invironment.
Term
Sodium Potassium-Pump
Definition
Transports Na+ and K+ up their concentration gradient
For every three Na+ ions pumped out of the cell 2 k+ ions are pumped in.
Term
Concentration Gradient
Definition
The difference in the concentration of molecules across space.
Term
Krebs cycle
Definition
The oxidation of glucose that begins when glycolysis is completed.
-has small amount of ATP
-Hans Krebs-Germany-1900-1981
Term
Osmosis
Definition
The process by which water molecules diffuse across a membrane from an area of higher concentration to an area of lower concentration.
It is a type of passive transport.
Term
Diffusion
Definition
Simplest type of passive transport.
Movement of molecules from an area of higher concentration to an area of lower concentration.
Term
Mitochondrion
Definition
The organelle that is the site of aerobic respiration in eukaryotic cells.
Term
Kinetic energy
Definition
Always in motion
Term
Glycolysis
Definition
A pathway in which glucose is oxidized into pyruvic acid; takes place in cytosol- chemical reaction
Term
Glucose
Definition
C6 H12 O6
Need a certain amount to keep body healthy
Also known as blood sugar.
Term
ATP
Definition
Adenosine Triphosphate- Made in cytosol- broken off to form energy
Term
Types of Fermentation
Definition
Lactic Acid + Alcoholic Fermentation
food examples: Grapes, Yeast, Barley, Bread.
Term
Aerobic vs. Anaerobic
Definition
Aerobic requires oxygen while Anaerobic does not
