Answer:
Sarcoplasmic reticulum.`
Explanation:
Muscle fibers are formed by the process of myogenesis in humans. These fibers help in the contraction of the muscle and also helps in the body movement.
Sarcoplasmic reticulum is a cell organelle present in the muscle fibers that corresponds to the structure of endoplamsic reticulum. Sarcoplasmic reticulum stores the calcium ions in the muscle fibers.
Thus, the answer is sarcoplasmic reticulum.
Answer:
Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue on to the Krebs cycle and oxidative phosphorylation. However, if oxygen is not present, some organisms can undergo fermentation to continually produce ATP.
Answer:
The correct answer is option D. all of the above.
Explanation:
The skeletal muscle is a type of striated muscle, that is controlled by the somatic nervous system. Tendons are the collagen fiber that binds these muscles to the bones.
Skeletal muscles are arranged in antagonistic pairs so if a muscle helps a joint to move so the other muscle can bring it to its original resting position. The point where muscle binds to an immovable bone called the origin of the muscle and the point where muscle attached to a movable bone its termed as insertion.
Thus, the correct answer is option D.
