Question

KIN 3313: Homework for Sliding Filament Theory of Muscle Contraction Place the list of the series of events occurring in the sliding filament theory of muscle contraction in the correct order: 1. 2. 3. 4. 5. 6. 7. 8. 9. 10 A. Ca+ is released from terminal cisternae B. troponin pulls tropomyosin covering binding sites on actin C. acetylcholine stimulates sarcolemma D. Ca+ leave sarcoplasmic reticulum E. tropomyosin changes uncovers binding sites on actin F. myosin pulls on actin causing power stroke G. depolarization wave travels down T-tubules H. acetylcholine is release from motor nerve l. nerve stimulation stops J. myosin binds to actin forming a cross bridge K. Cat is pumped into sarcoplasmic reticulum L. Ca+ binds with troponin on actin M. myosin disconnects from actin 12. 13.

Explanation / Answer

H. acetyl choline is released from motor nerve.

A. Ca+ is released from terminal cisternae.

C. acetylcholine stimulates sarcolemma.

G. depolarization wavetravels down T-tubules.

D. Ca+ leaves sarcoplasmic reticulum.

L. Ca+ binds with troponin on actin.

E. tropomysoin changes uncover binding sites on actin.

J. myosin binds to actin forming a cross bridge.

F. myosin pulls on actin causing power stroke

K. Ca+ is pumped into sarcoplasmic reticulum.

M. myosin disconnects from actin.

B. troponin pulls tropomyosin covering binding sites on actin.

I. nerve stimulation stops.
