The extra oxygen is used to restore muscle fibers to their pre-exercise state by doing all of the following except facilitating calcium release from the sarcoplasmic reticulum in the muscle fiber. Thus, the correct option is B. 
<h3>What is Respiration?</h3>
Respiration may be defined as the process of acquiring oxygen from outside the body and utilizing it in the process of breakdown of food sources for cellular needs. 
The extra oxygen works in the muscle fiber by replenishing the ATP, restocking the myoglobin, and supplying the ATP used to replenish glycogen stores in the muscle fiber. 
Therefore, the correct option for this question is B.

Answer:
The glucose making part of photosynthesis takes place in the stroma
explanation:
Stroma is the colorless liquid that surrounds the grana in the chloroplast inside plant cells. The stroma contains grana, and stacks of thylakoids in which photosynthesis is started before the chemical changes are completed in the stroma itself. The stroma functions by synthesizing organic molecules from water and carbon dioxide. In the stroma, an enzyme removes the carbon from carbon dioxide, and then combines it with hydrogen and oxygen and to form a simple carbohydrate molecule (glucose).
