active transmembrane transport - ANSWER-requires energy (low concentration to high
concentration)
adp - ANSWER-compound that remains when a phosphate group is removed from ATP,
releasing energy
anabolism - ANSWER-ana the builder; builds things up and creates energy (ex
photosynthesis)
atom - ANSWER-smallest unit of matter that retains elemental properties
atomic mass - ANSWER-protons + neutrons
atp adenosine triphosphate - ANSWER-main energy source that cells use for most of
their work
calvin cycle - ANSWER-light-independent reactions of photosynthesis in which energy
from ATP and NADPH is used to build high-energy compounds such as sugar
catabolism - ANSWER-break dancing cat; breaks things down and releases energy (ex
cellular respiration)
catalysis - ANSWER-the acceleration of a chemical reaction by a catalyst
cell membrane - ANSWER-cell structure that controls which substances can enter or
leave the cell
cellular respiration - ANSWER-uses sugar to make ATP (carbon and water is released)

low concentration)
electrons - ANSWER-negatively charged particles
element - ANSWER-type of atom that has certain characteristics
endocytosis - ANSWER-process by which a section of the plasma membrane of a cell
bulge inward to form a pocket around extracellular fluid or molecules that eventually
pinches off to become a vesicle contained within a cell
