Answer
The effects of ATP on muscle tissue
Solution
a
Before ATP was added: The muscle tissue appeared relaxed and in a resting state. The muscle fibers were not actively contracting, and there was no visible movement or tension in the tissue
b
Upon addition of ATP: The muscle tissue began to contract. The muscle fibers shortened, and there was a visible increase in tension and movement within the tissue. This contraction is due to the interaction of ATP with the myosin heads in the muscle fibers, allowing them to bind to actin filaments and perform the power stroke necessary for muscle contraction
Key Concept
ATP is essential for muscle contraction
Explanation
ATP provides the energy required for the myosin heads in muscle fibers to bind to actin filaments and perform the power stroke, leading to muscle contraction. Without ATP, muscles remain in a relaxed state.
