Energy Production
Energy Production
The chemical
process of converting food
into energy.
Bioenergetics
storage form of
glucose in animals
Glycogen
First 30 seconds of exercise
emphasizes
ATP-PC
What is another name for the krebs cycle
citric acid cycle
Hydrogen channels in the
membrane
allow hydrogen ions
to flow down their
concentration gradient
Plants convert sunlight to
carbohydrates
important
for metabolism at rest & in
exercise
Glucose & glycogen
generally provides
most energy for the first 2.5
minutes following ATP-PC
Glycolysis
what is the function of the Krebs cycle
oxidize substrates
phosphorylates
ADP to ATP
ATP synthase
Chemical is a form of energy, what are the three other forms
Electrical, Heat and Mechanical
Contained in both plant & animal
tissues
Fats
from glycolysis
can be converted to lactate
pyruvate
Produces majority of ATP during
aerobic metabolism, called oxidative
phosphorylation
Electron Transport Chain (ETC)
produce more ATP than those
from FADH2 because NADH
enters the ETC at an earlier
point.
Hydrogens from NADH
Carbohydrates is a rapid source of energy with 3 forms that are
Monosaccharides, Disaccharides, Polysaccharides
contains max number of hydrogen
atoms and no double bonds
Saturated fatty acid
What are the 3 Substrates
Fat, protein,
carbohydrates
also formed in
the last reaction of the Krebs
cycle, which is why it is called a
cycle.
Oxaloacetate
produces 2 ATPs per glucose molecule
Krebs cycle
also known
as blood sugar; can be used
for energy or stored as
glycogen
Glucose
Broken into 3 fatty acids and glycerol when needed for energy by
lipolysis
Triglycerides
2 Major Enzymatic Systems for Aerobic Metabolism
Krebs Cycle, Electron Transport Chain
what goes through a series of
reactions, resulting in 2 CO2 and 1
ATP
Citrate
Net is
32 ATP for glucose and 33 ATP for glycogen
