Question:
Describe what is meant by muscle fiber "cross-bridges". What occurs to enable movement of the cross-bridges?
Answer:
In the presence of calcium ions, portions of a myosin filament called cross- bridges bend backward and attach to an actin filament. After attaching to the actin filament, the cross-bridges bend forward, and the actin filament is pulled along. The cross-bridges attach and detach some fifty to 100 times as the thin filaments are pulled to the center of a sarcomere. ATP is needed on a cellular level for the myosin to pull actin along.
Question:
