1
Q
photosynthesis chemical energy
A
reduction, gains electrons
low energy (e- poor, oxidized) to high energy (e- rich. reduced)
2
Q
respiration chemical energy
A
oxidation, lose electrosn
high energy (e- rich, reduced) to low energy (e- poor, oxidized)
3

A
24 e-
24 e-
ATP
4
Q
ATP breaks down to
A
ADP, releases energy
5
Q
ATP is needed for
A
active transport
motility
chemical rxns
6
Q
enzymes
A
catalyst that facilitates chemical rxns
7
Q
how do enzymes help a rxn proceed?
A
by decreasing activation energy
8
Q
metabolic pathway
A
series of enzymes act to modify a substrate
9
Q
enzyme catalyzed reaction pathway
A
substrate (starting molecules) + enzyme (unique environment for substrate to bind) = product
