Explain, in terms of thick and thin myofilaments, why skeletal muscle appears striated under the microscope. Identify the bands of a sarcomere and which contractile proteins are in each band.
Added by Chad K.
Step 1
These myofilaments are organized into repeating units called sarcomeres, which give the muscle its characteristic striped appearance. Within a sarcomere, there are several distinct bands. The two main bands are the A band and the I band. The A band is the dark Show more…

What are the major components in thick and thin filaments, respectively? (2 marks) c. During the muscle contraction, how do these regions change in length? (4 marks) d. Despite the similarity of sarcomeres, compare the differences of cellular organization between skeletal muscle cell and cardiac muscle cell. (2 marks)
