What is chromatin reticulum?

What is endoplasmic reticulum ?

What do you mean by chromatin reticulum.

[A] : Upon stimulation of a muscle cell, cal- cium ions (Ca^(++)) are released from the sar- coplasmic reticulum. [R]: In reacting with a protein complex, Ca^(++) unmasks myosin binding sites on the ac-tin filaments.

Read the following statements (i) In cardiac muscle fibres sacroplasmic reticulum is poorly formed (ii)B Blood supply is scanty in case of smooth muscle fibres (iii) Tropomyosin occurs in actin filaments in the form of complexes which are arranged over actin fibres and represent sites where myosin binds to actin. (iv) Salts of citrate and oxalates act as anticoagulants as they precipitate Ca^(2+) Select the correct statements

What are Sarcoplasmic reticulum

The sarcoplasmic reticulum is identical with the endoplasmic recticulum of other cell type, with exception of ribosome.

Muscle protein __binds Ca^(2+) that is released from the sarcoptasmic reticulum.

Surface of endoplamic reticulum is covered with

The membrane of endoplasmic reticulum remains continuous with membrane of
