Mutations in the gene for troponin can result in the production of the troponin protein, which has varying affinities for Ca2+ ions. Suppose that in a muscle cell a mutant troponin is expressed that has such a high affinity for Ca2+ ions that once they bind to troponin they cannot unbind. What will likely happen in this muscle cell?
◦ Myosin heads will not bind to actin after action potentials stop being received.
◦ Cross-bridges will form between myosin and tropomyosin.
◦ Myosin heads will bind to actin after action potentials stop being received.
◦ Tropomyosin will not move to expose myosin binding sites.
