Ch 12 part 3 Fast Glycolytic Muscle Fibers Type llb

Glycolytic fibers have a very high concentration of cytosolic ______ enzymes.

Oxidative fibers have numerous ______ and can generate ATP easily through oxidative phosphorylation.

The cells that are stained dark and have a high oxidative capacity are very ______.

______-twitch muscle cells are able to generate ATP quite rapidly through glycolysis.

Capillaries are found in higher concentrations around the oxidative fibers because the ______ present in them require oxygen from the bloodstream.

Slow oxidative (Type I) muscle fibers contract ______ and primarily produce ATP aerobically.

Slow oxidative muscle fibers have a high content of ______, the red pigment that carries oxygen.

Fast oxidative-glycolytic (Type IIa) muscle fibers contract ______ and use both anaerobic and aerobic metabolic processes for ATP production.

Fast glycolytic (Type IIb) muscle fibers rely primarily on ______ respiration for ATP production.

Endurance runners are usually ______ because they have a lot of slow oxidative fibers.

Fast glycolytic (Type llb) muscle fibers contract ______ and primarily produce ATP anaerobically, through glycolysis.

These fibers are typically ______ due to their low myoglobin content.

If you know whether ATP production is ______ or anaerobic, you can predict whether myoglobin content will be high or low.

Individual motor units possess just one of the three ______ types described above.

Fast ______ fibers, located in the large motor units, are not usually recruited except when the muscle must generate a sudden, large force.

______ fibers have numerous mitochondria and can generate ATP easily through oxidative phosphorylation.

______-twitch muscle cells are able to generate ATP quite rapidly through glycolysis.

Capillaries are found in higher concentrations around the ______ fibers because the oxygen present in them require oxygen from the bloodstream.

Glycolytic fibers have a very high concentration of cytosolic ______ enzymes.

The cells that are stained dark and have a high oxidative capacity are very ______.

The muscles of a sprinting track runner will differ from the muscles of a marathon runner, and they will both differ from the muscles of a person who leads a ______ lifestyle.

Over time, fast-glycolytic (Type ______) fibers are converted to fast-oxidative-glycolytic (Type Ila) fibers.

High intensity exercise over a short duration increases the ______ capacity of fibers but lowers their oxidative capacity.

Glycolytic fibers have a very high concentration of cytosolic ______ enzymes.

Oxidative fibers have numerous ______ and can generate ATP easily through oxidative phosphorylation.

For exams, remember that ______ training enhances the oxidative capacity of muscle fibers and reduces their chances of becoming fatigued.

When studying for exams, keep in mind that ______ exercise increases the glycolytic capacity of muscle fibers but lowers their oxidative capacity.

As an exam tip, recall that the muscles of a ______ runner will have more numerous and larger mitochondria than an average person's.

For exams, remember that over time, fast-glycolytic (Type ______) fibers are converted to fast-oxidative-glycolytic (Type IIa) fibers.

When studying for exams, keep in mind that ______ fibers are typically pale due to their low myoglobin content.
