Term
Creatine phosphate
Definition
a molecule unique to muscle
works by converting some of the energy-depleted ADP molecules back into ATP molecules by transferring its phosphate to ADP, a reaction that generates creatine plus ATP
Term
Glycolysis
Definition
the breakdown of glucose into pyruvate
fastest method of generating ATP from nutrients
Term
Glycogenolysis
Definition
when glycogen is broken into individual glucose molecules which are then used to generate ATP
catalyzed by an enxyme
Term
Lactic Acid
Definition
what pyruvate is frequently converted to
will be converted back into pyruvate
some converted into glucose
Term
mitochondria
Definition
contain a host of enzymes that completely break down various nutrients and generate large amounts of ATP
provide a slow and steady flow of ATP
Term
Fatigue
Definition
when muscle is vigorously exercised for a long time, it loses the ability to respond to nerve stimulation
fiber contraction becomes weaker and weaker and finally stops
