Question

how does the structure of skeletal muscle help perform its function

Answer 1

Skeletal muscle cells exist in the form of long fibers, about 30 cm in length on average. This length allows the skeletal muscles to pull on bones when they contract and this is how they enable movement. The skeletal muscles are attached to the bones of the body through strong band of connective tissue fibers known as tendons that help to pull on the bones. 

Answer 2

Answer: The sarcomeres in a skeletal muscle help perform its function.

Explanation:

Something you will notice about skeletal muscle cells is they have a very striated look. Its striations allow big movements. Skeletal muscle cells also have sarcomeres, which can also be referred to as units that help cells contract or relax together, which is what gives skeletal muscles the ability to contract/produce movement. The sarcomeres allow the cells to work together in order to produce contractions and relaxations at the same time.
