3 systems the body generates Phosphocretaine (PCR/Phosphagen
ATP System)
Glycolysis (aerobic and anaerobic)
Oxidative Phosphorylation (citric and
Krebs, ETC)
2 ways ATP can be aerobically
resynthesizes anaerobically
how is anaerobic ATP phosphocreatine (PCr)
resynthesis fueled by Glucose/Glycogen
deaminated protein (if necessary)
how is aerobic ATP synthesis pyruvate from glucose/glycogen
fueled fatty acids
deaminated protein (if necessary)
where does PCr/phosphagen cytosol
system occur
what does ATP do powers all necessary cellular responses
that require energy
, where is the energy stored in in the bonds
ATP
how much energy is stored in about 7.3 kcal/mol
the bonds of ATP
what does ATP break down ADP and Pi
into
how many grams of ATP are 80-100 grams
stored in normal conditions
how many seconds of energy 2-3 seconds
are available via the stored
ATP in the body
what enzyme hydrolyzes PCr certain kinase
and yields a free phosphate
(Pi) group
in the PCr system, what two ADP and Pi
groups/pieces can be
phosphorylated back into
ATP?
True or False: cells store 4-6 true
times more PCr than ATP
what are the two names for glycolysis and glycogenolysis
the reactions that breakdown
glucose or glycogen into ATP
