Question

Use Figure 10-1 to answer the following Figure 10-1 Skeletal Muscle Fiber 16) structure actively pumps calcium ions out of the sarcoplasm to produce A)7 relaxation? E) 6 B) 1 C) 3 D)2 17) A) tendonof connectivissue that surrounds an entire skeletal muscle is the B) fascicle C) perimysium D) epimysium E) endomysium. 17) The dense la 18) 18) The area in the center of the A band that contains no thin filaments is the A) zone of overlap. B) M line C) I band D) Z line. E) H band 19) . 19) Since each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber A) weakens. B) lengthens C) shortens. D) strengthens. E) not enough information to say

Explanation / Answer

The structure that is responsible for maintaining the concentration of the calcium inside the muscle cell is SARCOPLASMIC RETICULUM which is present inside the muscle fibres. It makes calcium ions to pumps out and gives relaxation of the muscle. So the answer is 6
