, energy - ANS The capacity to do work. Cellular work includes processes such as building
complex molecules and moving substances into and out of the cell.
biofuels - ANS renewable fuels made from living organisms
fossil fuels - ANS Carbon-rich energy sources, such as petroleum, natural gas, and coal, which
are formed from the compressed, fossilized remains of once-living organisms.
chemical energy - ANS potential energy stored in the chemical bonds that hold chemical
compounds together
K
conservation of energy - ANS The principle that energy cannot be created or destroyed, but
can be transformed from one form to another.
C
potential energy - ANS stored energy
LO
kinetic energy - ANS energy due to motion
heat - ANS The kinetic energy generated by random movements of molecules or atoms.
Photosynthesis - ANS The process by which plants and algae harness the energy of sunlight
YC
to make sugar from carbon dioxide and water.
autotrophs - ANS Organisms such as plants, algae, and certain bacteria that can make their
own food from inorganic starting materials (e.g., CO2).
heterotrophs - ANS Organisms, such as humans and other animals, that obtain energy by
D
consuming organic molecules that were produced by other organisms.
Chloroplast - ANS The organelle in plant and algae cells where photosynthesis occurs.
U
light energy - ANS a type of electromagnetic radiation that includes visible light
ST
photons - ANS Packets of light energy, each with a specific wavelength and quantity of energy.
chlorophyll - ANS The pigment present in the green parts of plants that absorbs photons of
light energy during the "photo" reactions of photosynthesis.
Adenosine Triphosphate (ATP) - ANS The molecule in cells that powers energy-requiring
functions.
carbon fixation - ANS The conversion of inorganic carbon (e.g., CO2) into organic forms (e.g.,
sugars like glucose, C6H12O6.
