Muscles do store a form of glycogen for energy conversion.
sec
Fats store energy for the body and other nutrients such as Vitamin A and D.
The major storage form of energy in animals is glycogen ,it is stored in glycogen granule . Therefore glycogen granules in muscle cell act as stores of energy , since muscle cells requires alot of energy to perform their functions.
B excess fat stores are burned for energy
Creatine Phosphate cannot directly supply energy to a cell, instead, it stores energy released from mitochondria. Whenever sufficient ATP is present, an enzyme in the mitochondria (creatine phosphokinase) promotes the synthesis of creating phosphate, which stores excess energy in its phosphate bond.
regular aerobic exercise decreases the fat-to-muscle ratio because the answer is excess fat stores are burned for energy
Cells that do a lot of work or activity such as muscle cells.
muscle proteolysis
No.
Protein is needed for muscle growth and repair. Regular physical training tends to reduce muscle protein breakdown and protein loss from the body. While some protein breakdown may occur during exercise, protein build-up is enhanced during the recovery and the effectiveness of protein synthesis is increased. When muscle glycogen stores are high, protein contributes no more than 5% of the energy needed. However, when muscle glycogen stores are low, due to inadequate calorie and carbohydrate intake, protein is used for energy rather than for muscle growth and repair and may contribute as much as 10% of the energy needed for exercise. Such use of protein for fuel is expensive and inefficient.

Since the mitochondria produces energy and the muscle cells are part of the mitochondria, they use the energy so they can move the joints.
