Introduction to Metabolism
Overall stoichiometry: 4ATP + 4H2O
4ADP + 4Pi. These pathways must
be independently controlled or the ATP formed in glycolysis would be
automatically used in gluconeogenesis thereby uselessly dissipating the ATP
See Figures 17-1 and 17-3.
The aldolase reaction is:
DHAP + GAP
= " K'% [GAP]
But, according to equation [3.16],
(a) A reducing end of a polysaccharide chain has a free C1OH group. Hence, a
glycogen molecule has but one reducing end, no matter what its degree of
polymerization or branching.
(b) A glycogen molecule of 100,000 residue
