Within the first few seconds of a 5-minute race, stored ATP isdepleted. How do muscles obtain energy for the rest of the race?a. High-energy phosphates are transferred from glycogen to ADP.b. Creatine phosphate restores the ATP supply at first; then aerobicrespiration generates ATP as long as O2 is available.c. Actin filaments donate the high-energy phosphates that myosinfilaments require.d. Fermentation begins producing new ATP as soon as stored ATP isdepleted.

What do skeletal muscle contractions share in common with smooth muscle contractions?a. Both types of contractions do not require calcium ions for a contraction to occur.b. Both types of contractions generate little force or a weak force.c. Both types of contractions consume very little ATP.d. Both types of contractions result from thick and thin filaments sliding past one another.

Myosin binds to actin, then bends. What is ATP needed for next? A. to pump the Ca++ “keys” back into the sarcoplasmic reticulum B. to replace the strap and cover the binding sites C. to give feedback to the neuron that contraction occurred D. to un-bind myosin from actin and re-set for another powerstroke.
