Question

explain discuss the role of CA + 2 ions in muscle contraction

Answer 1

muscle contraction is initiated by a neural signals after reaching the neurotransmitter muscular junction or motor end plate release a neurotransmitter as a result and action potential is in the sacrolemma is generated action potential spread through muscle fibre and caused the release of calcium Ion into the sarcoplasm increase in CA + 2 Level leads to the binding of calcium with subunit of troponin and on actin filaments and thereby room removing the masking of active sites for my meiosis in utilising the energy from ATP hydrolysis the meiosin and now binds to the active site on acting to form a cross breed this pulls the attached actin filaments towards the centre of A band the Z line attached to these actin filaments there by causing shortening of the saccomere made that is contraction

ATP binds to my house in head and the cross Bridge is broken the ATP is cane hydrolysed by the miocene head and cycle of crossroads formation and breakage is repeated causing for the sliding the process continuous till the C + + ions are pumped back to the sacro plasmic cisternae resulting in masking of actin filaments and breakage of all cross bridges
this cause the return of Z lines along with filaments back to their original position
that is relaxation

Answer 2

heya!!

here is your answer ⤵️⤵️

The role of CA+2 ions in muscle contraction

• It helps in movement of body.

• It gives certain energy for contraction.

•They prevent from Myosin and Actin

• They react with Proteins

• They create interaction between protein , myosin and actin
