explain why a person bringing 50 kg sack of rice will not move in the same speed and duration as one running in a marathon based on the concept of skeletal muscle contraction
Step by step
Solved in 2 steps
- In the process of muscle contraction, which of the following steps immediately precedes the sliding of tropomyosin causing exposure of actin? binding of acetylcholine to its receptor binding of calcium to troponin exocytosis of acetylcholine at NMJ binding of myosin head to actin's active site binding of ATP to the myosin headIn the process of muscle contraction, which of the following steps requires hydrolysis of ATP to complete? movement of myosin head, pulling the thin filament binding of myosin head to active site on actin resetting of the myosin head back to its ready position letting go of myosin head from the active site on actin sliding of tropomyosin causing exposure of actinIn the process of muscle contraction, which of the following steps immediately comes after the propagation of an action potential down the t-tubules of a myofiber? sliding of tropomyosin causing exposure of actin binding of myosin head to actin's active site release of calcium from the terminal cisternae binding of acetylcholine to its receptor influx of sodium at the sarcolemma
- In the process of muscle contraction, which of the following steps immediately precedes the influx of sodium into a myofiber at the neuromuscular junction? release of calcium from the terminal cisternae sliding of tropomyosin causing exposure of actin propagation of an action potential down the t-tubules binding of myosin head to actin's active site binding of acetylcholine to its receptorHow is the list below to be properly put in order to describe a muscular contraction? 1. Calcium causes exocytotic release of Acetylcholine into the synaptic gap; all this happens at an area called the neuromuscular junction2. ATP is consumed which allows myosin to "pivot" the myosin head, which pulls actin toward it.3. This process is repeated multiple times and is called the "sliding filament theory".4. Myosin filaments perform "crossbridging".5. Calcium is released and circulated throughout the muscle cell6. The brain predicts the action necessary and decides which muscles and how many "motor units" are needed to perform that action.7. Tropomyosin moves to reveal the active site of the F-Actin strand8. Upon reception of a calcium ion, the Troponin complex becomes activated9. Proteins embedded in the Sarcolemma receive enough of the ACH neurotransmitter to generate an electrical impulse.10. The electrical impulse is perpetuated throughout the muscle fiber.11. A nervouse impulse is…For the skeletal muscle, hydrolyzation of ATP: Group of answer choices At the myosin head gives rise to the generation of power stroke. At the actin G-molecule gives rise to the generation of power stroke. At the myosin head give rise to the rotation of myosin head to the "cocked back" position. At the actin G-molecule give rise to the rotation of myosin head to the "cocked back" position.
- With regard to muscle contraction, which of the following is an INCORRECT statement with regard to the interactions of filaments that occur in the sarcomere? A. When muscles are relaxed tropomyosin blocks binding sites on actin subunits, which keeps cross-bridges from forming. B. The myosin heads conduct a power stroke motion to slide when bound to actin, to move the "thin" filaments towards the center of the sarcomere. C. During contraction, actin subunits are removed from the ends of the "thin" filaments to shorten actin polymers, thus reducing the length of the sarcomere. D. "Thick" filaments are anchored at the M-line, while "thin" filaments are anchored at the Z-line. E. Numerous myosin heads engage with the actin filaments simultaneously, such that there is no back-slipping during the contraction process.In an isometric contraction, how can the muscle stay the same length when the muscle is contracting? Can choose more than one - The muscle is not able to generate more (or the same amount) force than the load, preventing shortening of the muscle. - Calcium stops entering the sarcoplasm when the desired length is reached. - Elastic elements of the muscle stretch in response to the contraction of the muscle, so that the muscle stays the same size despite shortening sarcomeres. - The myosin heads detach from actin when they reach the desired length.The sliding filament model of contraction is a theory that is used to explain how muscles contract to cause movement. The theory explains that the change in the length of the muscle during contraction is due to the sliding of the myofilaments past each other and not to a change in the length of either of the myofilaments.
- Explain the concept of the following in regard to muscle cells: sliding filament movement does not need to be a super indepth answerUsing a well annotated diagram explain the sliding filament theory of muscle contractionThe sliding filament model depicts how myosin motors attached to actin lead to muscle contraction. This process proceeds in a precise series of events. Indicate which of the following shows the correct order of steps in the sliding filament model. Group of answer choices Myosin binds ATP; myosin tightly binds actin; power stroke; myosin releases actin Myosin binds GTP; myosin releases actin; power stroke; myosin tightly binds actin Actin binds ATP; power stroke; myosin tightly binds actin; actin releases ADP Actin binds ADP; myosin releases actin; power stroke; actin releases ADP
