Final answer:
B-Glycosomes and myoglobin Skeletal muscles have glycosomes for glycogen storage and myoglobin for oxygen binding, both essential for muscle contraction; the correct answer is glycosomes and myoglobin.
Step-by-step explanation:
The skeletal muscles contain two special inclusions that are critical to their role in movement. These are glycosomes and myoglobin. Glycosomes are specialized granules that store glycogen, which can be rapidly mobilized to glucose for ATP production to power muscle contractions. Myoglobin, on the other hand, is a protein that binds oxygen and is responsible for the red color of muscle tissue. It serves as a reservoir of oxygen within the muscle cells and improves the efficiency of oxygen utilization for ATP production essential during muscle contraction. Therefore, the correct answer is B-Glycosomes and myoglobin.
Glycosomes are organelles found in skeletal muscle fibers that store and break down glycogen, which is the main source of energy for muscle contractions.
Myoglobin is a protein found in skeletal muscle fibers that binds and stores oxygen. It allows muscles to have a ready supply of oxygen for aerobic respiration during exercise.
