Based on the advice of public health officials and our own concerns about the well-being of students and instructors, we’ve decided to move everything to the safety of online course delivery.
It was a difficult decision but we believe it is the responsible thing to do amid a resurgent pandemic with proliferating variants of concern.
A researcher is studying the mechanism of muscle contraction. They observe that the binding of a specific molecule to the myosin head is the most direct cause of its dissociation from the actin filament.
Which of the following molecules is most directly responsible for releasing the myosin head from the actin filament?
The correct answer is B. ATP. In the cross-bridge cycle of muscle contraction, when an ATP molecule snags a spot on the myosin head, it changes its shape. This makes myosin lose its grip on the actin filament, letting it detach so the cycle can go again.
