where does the production of ATP occur - ANS mainly the mitochondria, but also in the
cytoplasm of a cell
if the enzyme in the mitochondria was competitively inhibited with cyanide - ANS active
transport would stop
enzyme - ANS protein
function of an enzyme - ANS change the rates of chemical reactions

what controls a metabolic pathway - ANS enzymes
what are the two kinds of processes involved in metabolism - ANS catabolic and anabolic
catabolic process - ANS larger molecules are broken down into smaller ones
anabolic process - ANS larger molecules are built from smaller molecules
the rate of anabolic processes is ___________ than catabolic processes - ANS faster
