Question
Chapter 10.4, Problem 19BYGO
Summary Introduction
To write:
The reason for the movement of tropomyosin before the contraction of muscle fibre. The factor that facilitates the movement of tropomyosin.
Introduction:
Muscle is a bundle or band of fibrous tissue present in a human or animal body. It can contract and move in preserving the position of body parts. Muscles play a role in the production of force and motion. They are mainly responsible for sustaining and shifting posture and locomotion.

What structures/s is/are responsible for the banding pattern in skeletal muscle cells? (EXPLAIN)
Explain the sliding filament theory of contraction.
NO COPYPASTE FROM THE INTERNET, PLEASE! I ALREADY WASTED MY QUESTIONS TO SOME VERY SHORT and COPY-PASTED ANSWERS.
Number the following statements in the proper sequence to describe the contraction mechanism in a skeletal muscle cell ( select number from 1 to 12)
Action potential (AP) arrive at axon terminal at neuromuscular junction (NMJ)
[ Choose ]
The muscle cell relaxes and lengthens
[ Choose ]
SR releases calcium and it binds to troponin
[ Choose ]
Myosin heads bind to actin and contraction begins
[ Choose ]
Ion permeability of sarcolemma changes and sodium begins entering muscle cell causing depolarization
Calcium flows into presynaptic terminal to initiate neurotransmitter release
[ Choose ]
AP travels across the entire sarcolemma
[ Choose ]
Ach is released and binds to receptors on the sarcolemma
[ Choose ]
Local depolarization (end plate potential) ignites AP in sarcolemma
[ Choose ]
Troponin moves tropomyosin out of the way of myosin binding sites on actin
[ Choose ]
AP travels along T tubules
[ Choose ]
Cross bridge cycling continues until ATP runs out and/or calcium is…
Now in your own words, EXPLAIN (1) howa neural impulse is transferred to a muscle cell
this is the process of “muscle excitation"), and (2) how the electrical impulse travels into
he T-tubules and causes calcium to be released from the sarcoplasmic retículum (this is the
process of “excitation-contraction coupling"):

Tropomyosin shifts, exposing the myosin-binding sites on actin. 2. Calcium is released from the sarcoplasmic reticulum and binds to the troponin complex. 3. An action potential is propagated down the transverse tubules. 4. Cycles of myosin cross-bridge formation and breakdown cause the thin filaments to slide toward the center of the sarcomere. 5. An action potential in a motor neuron causes the axon to release acetylcholine, which triggers an action potential in a muscle fiber. 1 → 2 → 3 → 4 → 5 3 → 2 → 4 → 1 → 5 2 → 1 → 3 → 5 → 4 5 → 3 → 2 → 1 → 4 4 → 3 → 1 → 2 → 5arrow_forward
