Read the following statements and choose the following option: 1. In resting state the active binding sites on actin is open 2. Thick filament is composed of monomers of proteins. 3. Fascicles are held together by a common collagenous connective tissue layer called fascia. 4. A neural signal reaching Neuromuscular junction releases a neurotransmitter (Acetyl choline) which generates an action potential in the sarcole

Options

  1. ABoth 1 and 4 are incorrect
  2. BBoth 2 and 5 are correct
  3. COnly 2 is correct
  4. DOnly 1 is incorrect

Correct answer

D. Only 1 is incorrect

Step-by-step solution

Each myosin (thick) filament is also a polymerised protein. Many monomeric proteins called Meromyosins.,A neural signal reaching this junction releases a neurotransmitter (Acetyl choline) which generates an action potential in the sarcolemm,Increase in Ca++ level leads to the binding of calcium with a subunit of troponin
