a protein found in muscle cells, is responsible for relaxing and contracting all muscles cells in your body. Myosin is able to contract muscle "walking" along the muscle fiber shown in the below.You see the myosin in along in gold. Which of the following statements explains how the myosin is able to use energy to move along muscle fibers? Myosin breaks the bonds in its amino acid chain to make ATP and move along the muscle cells. Myosin breaks bonds in ATP to release energy that allows the myosin to move up the muscle cell allowing it to contract. Myosin breaks down ATP to make quick energy in the form of glucose to contract the muscle cells. Myosin uses important energy molecules like glucose to energize the muscle cell by adding a phosphate group to ADP to make ATP. 10 points 10 points

Answer 1

The correct statement explaining how myosin is able to use energy to move along muscle fibers is:Myosin breaks bonds in ATP to release energy that allows the myosin to move up the muscle cell allowing it to contract.

Answer 2

## Step 1The process of muscle contraction involves the interaction between myosin and actin filaments within muscle cells. Myosin is a motor protein that can convert chemical energy stored in adenosine triphosphate (ATP) into mechanical energy, which is used to produce movement.## Step 2The energy for muscle contraction is provided by the hydrolysis of ATP. Myosin has an ATPase activity, which means it can catalyze the breakdown of ATP into adenosine diphosphate (ADP) and an inorganic phosphate (Pi). This reaction releases energy that myosin uses to change its conformation and "walk" along the actin filaments. This walking motion is part of the cross-bridge cycle, which is essential for muscle contraction.## Step 3The options provided suggest different mechanisms by which myosin might obtain energy for movement. We need to identify the correct mechanism that reflects the actual biochemical process occurring in muscle cells.
