Question

complete each sentence with the correct word or phrase to explain the sliding filament theory of muscle contraction. 1. atp is hydrolyzed by click to select, which is in the myosin head. 2. the myosin head is bound to click to select when it is in the extended, high - energy conformation. 3. the myosin head is bound to click to select when it is in the low energy conformation and is not bound to the thin filament. 4. the myosin head is bound to click to select when it is in the low energy conformation, and it is bound to the thin filament. 5. the myosin head is bound to click to select during the power stroke. 6. the absence of click to select would prevent the myosin head from detaching from the thin filament. adp and pi atp atp hydrolase atp, adp and pi camp myosin atpase no nucleotide

Explanation:

1. Myosin - ATPase in the myosin head hydrolyzes ATP.
2. In the extended, high - energy conformation, myosin head is bound to ADP and Pi.
3. In the low - energy conformation not bound to thin filament, myosin head is bound to no nucleotide.
4. In the low - energy conformation bound to thin filament, myosin head is bound to ADP.
5. During the power stroke, myosin head is bound to the thin filament.
6. Absence of ATP would prevent myosin head from detaching from thin filament.

Answer:

1. myosin ATPase
2. ADP and Pi
3. no nucleotide
4. ADP
5. the thin filament
6. ATP
