Questions & Step-by-Step Solutions

Which protein is primarily responsible for muscle contraction? (2019)
  • Step 1: Understand that muscles are made up of proteins.
  • Step 2: Identify the two main proteins involved in muscle contraction: myosin and actin.
  • Step 3: Learn that myosin is the protein that pulls on actin to cause muscle fibers to shorten.
