Biology
Homeostasis
The tendency for a system to maintain
relatively constant internal conditions.
Diffusion
The movement of particles from an area of higher
concentration to an area of lower concentration;
does not require energy. The particles will continue
to move until they are evenly dispersed.
Osmosis
The movement of a solvent across a semi-permeable
membrane from an area of low solute concentration to
an area of high solute concentration to equalize the
solute concentration on both sides of the membrane.
Active Transport
The movement of substance across the
membrane that requires the use of energy;
moves against the concentration gradient.
Photosynthesis
The process by which autotrophic organisms
capture light energy to convert carbon dioxide
and water into glucose, thereby storing some of
the captured energy in chemical bonds.
Cellular Respiration
(cell respiration)
The process by which cells use electron
transport chains to transfer the energy in
nutrient molecules to the chemical bonds of ATP.
Adenosine Triphosphate (ATP)
The primary molecule used by cells to store
chemical energy for use in cellular processes.
Nucleic Acid
A nucleotide polymer capable of storing and
transferring genetic information.
Amino Acid
A molecule containing an amine group, a
carboxylic acid group, and a side chain that is
specific to each type of amino acid.
Protein
A biomolecule made of one or more amino
acid polymers folded into a complex structure
that performs a specific function.
Metabolism
Anabolis
m
Catabolis
m
The set of chemical reactions within a
cell or organism that maintain life.
Passive Transport
Movement across a cell membrane
without using energy.
Semi-Permeable
(selectively permeable)
Allowing only some materials
to pass through a membrane.
