Textbook Question
Chapter 46, Problem 2A
You have identified a calcium storage disease in rats. How would this inability to store Ca2+ affect muscle contraction?
a. Ca2+ would be unable to bind to tropomyosin, which enables troponin to move and reveal binding sites for cross-bridges.
b. Ca2+ would be unable to bind to troponin, which enables tropomyosin to move and reveal binding sites for cross-bridges.
c. Ca2+ would be unable to bind to tropomyosin, which enables troponin to release ATP.
d. Ca2+ would be unable to bind to troponin, which enables tropomyosin to release ATP.
