and one strand of regulatory protein while thick filaments are being staggered arrays of

Question 5

what are parts of the sliding filament model

Answer 5

the sarcomere and z lines

Question 6

what is the sliding-filament model

Answer 6

the sliding-filament model is filaments slide past each other longitudinally,
producing more overlap between thin and thick
filaments

Question 7

how does contraction work (with bad analogy)

Answer 7

the myosin head is going back and forth between contracted and relaxed states due to atp and wants to be with the thick filaments so but its being blocked by troopsin and tropsion and when Ca+ comes in it moves so mysosin can with there love

Question 8

dissorders

Answer 8

ASL interferes withe excitation of the fibres this is usually fatal, Myasthenia gravis is autoimmune that attacks the attacks acetylcholine receptors, tetanus the constant painful contraction of muscles
