which is a true statement regarding smooth muscle cells
a)They are multinucleated
b)they have T-tubules
c) they involve calmodulin
d)they involve troponin
Homework Answers
The smooth muscle does not contain the calcium-binding protein troponin. This is the property of skeletal muscles. The smooth muscle has calmodulin which is important in the contraction of smooth muscles. These are uninucleated and ar pres tin various organs.
The answer is C.

Calmodulin is found in smooth muscle cells and performs a similar function to troponin in striated muscle fibers. However, calmodulin not only gets activated by Ca2+ but also slows the release of Ca2+ from the sarcoplasmic reticulum. How might this difference relate to the different kinds of contractions smooth muscles do in comparison to striated muscles? A study of muscle fibers between chimpanzees and humans revealed that although muscle mass per body size is approximately equivalent, the ratio of red...
