Solution
The correct answer to the question is: depends.
Explanation
The amount of force generated in a single muscle fiber is influenced by the number of cross-bridges formed between the thick and thin filaments within the muscle contractile units known as sarcomeres. When a muscle fiber is activated, myosin heads attach to actin filaments, forming cross-bridges. The more cross-bridges that can form, the greater the force generated by the muscle fiber. This relationship is crucial for understanding muscle contraction and the mechanics of muscle strength. Thus, the force generated indeed "depends" on the number of cross-bridges formed.
