Biology
Homeostasis
The process of maintaining a
constant state of balance.
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 diffusion of water across a membrane.
Active Transport
The movement of substances across the membrane
that requires the use of energy; moves against the
concentration gradient.
Photosynthesis
The process in which autotrophic cells
convert light energy into chemical energy
in the form of glucose.
Cellular Respiration
(cell respiration)
The process in which cells convert the chemical energy
from glucose into the energy storage molecule of ATP.
Adenosine Triphosphate (ATP)
A molecule that stores the energy that
powers the cells.
Nucleic Acid
A biomolecule composed of nucleotides which
carries the genetic information of an organism.
Amino Acid
Molecule that contains an amine group, a carboxylic acid
group, and a side chain specific to each amino acid.
Protein
A biomolecule composed of amino acids
connected by peptide bonds.
Metabolism
Anabolis
m
Catabolis
m
All of the physical and chemical processes
that occur within an organism.
Passive Transport
Movement across a cell membrane
without using energy.
Semi-Permeable
(selectively permeable)
Allowing only some materials to pass
through a membrane.
