Cellular Energy, Chemical Reactions, and Metabolic Pathways
Compare physical and cellular definitions for the term
"energy".
Physical: The ability to do work
Cellular: The ability to make specific changes occur
Name and describe five sorts of energy changes that occur in
cells.
Biosynthesis
Movement
Concentration of substances
Generation of electrical potential
Heat
Biosynthesis
The building up of biomolecules or biological structures within a
living cell; a process that requires energy
(Synthetic work is demonstrated by the making of daughter cells
from a parent cell)
Movement
Represented by the streaming movement of the cytoplasm
Concentration of substances
effected by active transportation
Energy of Concentration
the work of moving molecules or ions against a concentration
gradient, that is, moving them from where they are less
concentrated to where they are already more concentrated
Electrical potential
A difference in charge across a membrane based on a difference
in the concentration of positive and or negative ions across the
membrane
Cathedrals and cells
require energy for their construction
Energy
is the ability to make a specific changes occur within a cell
