muscle response to stronger stimuli
tetanus produces stronger (more forceful) muscle contractions, but its primary role is to produce smooth and prolonged (1.
)
contractions. how forcefully a muscle contracts depends to a large extent on how many of its cells are stimulated. when only a few cells are
stimulated, the muscle as a whole (2.
) only slightly. when all the motor units are active and all the muscle fibers are stimulated, the
muscle contraction is as strong as it can get. thus, muscle contractions can range from slight to vigorous depending on the (3.
) to be
done. the same hand that lifts a single sheet of paper can also lift a heavy backpack full of books!
providing energy for muscle contraction
as a muscle contracts, the bonds of atp molecules are hydrolyzed to (4.
) the needed energy.
conceptlink
recall that atp can be compared to a tightly coiled spring that is ready to uncoil with tremendous energy when the “catch” is released (chapter 2, p.
55). remember that all bonds store (5.
) and that the “catch” in this example is one of the characteristic high - energy phosphate bonds in
atp.

Explanation:

1. Tetanus produces smooth and prolonged work. When few cells are stimulated, the muscle contracts slightly. The strength of muscle - contraction depends on the work to be done. As muscle contracts, ATP bonds are hydrolyzed to release energy. All bonds store energy.

1. work 2. contracts 3. work 4. release 5. energy
