TERM 2
Cellular Respiration
DEFINITION 2
Cellular respiration is the set of the metabolic reactions and
processes that take place in the cells of organisms to convert
biochemical energy from nutrients into adenosine
triphosphate (ATP), and then release waste products.
TERM 3
Electron Transport Chain
DEFINITION 3
An electron transport chain (ETC) couples electron transfer
between an electron donor (such as NADH) and an electron
acceptor (such as O2) to the transfer of H+ ions (protons)
across a membrane.
TERM 4
Oxidation Reaction
DEFINITION 4
Redox (shorthand for REDuction-OXidation) reactions
describe all chemical reactions in which atoms have their
oxidation number (oxidation state) changed.
TERM 5
Mitochondria
DEFINITION 5
In cell biology, a mitochondrion (plural mitochondria) is a
