Question

question 1-16
myosin, a protein found in muscle cells, is responsible for relaxing and contracting all muscles cells in your body. myosin is able to contract muscle filaments by walking along the muscle fiber. this walking requires energy, as shown in the diagram below. you can see the myosin in pink and the muscle fiber it is walking along in gold.
which of the following statements explains how the myosin is able to use energy to move along muscle fibers?
myosin breaks down atp to make quick energy in the form of glucose to contract the muscle cells.
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 uses important energy molecules like glucose to energize the muscle cell, by adding a phosphate group to adp to make atp.

Explanation:

La miosina es una proteína motor que se utiliza en la contracción muscular. La energía para el movimiento de la miosina se obtiene de la hidrólisis de ATP. Cuando la miosina quebra los enlaces en ATP, se libera energía que permite que la miosina se mueva a lo largo de la fibra muscular, lo que permite la contracción muscular.

Answer:

Myosin breaks bonds in ATP to release energy that allows the myosin to move up the muscle cell allowing it to contract.
