Final answer:
Glycosomes store glycogen for energy, while myoglobin facilitates oxygen transport and storage within muscle cells, both crucial for muscle contraction.
Step-by-step explanation:
The functions of glycosomes and myoglobin are integral to the metabolic processes in muscle cells. Glycosomes, also called glycogen granules, are specialized organelles that store glycogen, an energy reserve carbohydrate in animals, and they release glucose when energy is needed for muscle contraction. Myoglobin, on the other hand, is a red protein that binds oxygen within the muscle cells, facilitating the transport and storage of oxygen for when it is needed during the muscle contraction process. This oxygen reserve is particularly important for muscle tissues that are highly active and require large amounts of oxygen to meet energy demands.
