NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyWhat are the sequential steps in the formation and breakage of a cross-bridge in muscle contraction?
| 1. | Myosin head hydrolyzes ATP, attaches to actin, performs a power stroke, and releases ADP. |
| 2. | Myosin head binds to ATP, detaches from actin, hydrolyzes ATP, and reattaches to actin. |
| 3. | Myosin head releases ADP, binds to ATP, detaches from actin, and hydrolyzes ATP. |
| 4. | Myosin head attaches to actin, performs a power stroke, binds ATP, and then detaches from actin. |
