Sliding filament theory is a model used to explain the mechanism by which muscles contract. The contraction of skeletal muscle, which is what makes movement possible, occurs in three ways.
Focus on what happens at the level of the sarcomere. This theory of muscle contraction is often called the âsliding filament theory.â Find three legitimate sources of information that include diagrams, pictures or animations. Write the name of each site as well as the associated web address in your laboratory notebook.n Activity 4.2.4, you learned that ATP is required for successful muscle contraction. Now you will zoom in on the sarcomere, the smallest unit of a muscle, and see exactly how ATP is used to make a muscle contract and relax. The sarcomere is made up of two important proteins, actin and myosin.
