Question

Which of the following is FALSE? Muscle cells contain myosin II, which is responsible for contraction. Myosin I is the only family to have a single head domain. The myosin with the largest step size is myosin II, which is used for muscle contraction. Organellar transport is accomplished by myosin V.

Answer 1

Answer: Muscles cell contain myosin II, which is responsible for muscle contractions.

Explanation:

Myosin are motor proteins that are responsible for muscle contractions and motility processes in animals.

Myosin II is also called conventional myosin is a form of myosin found in muscles cells and are responsible for muscles contraction in animal cells. It is found in non muscles cells called stress fibers.
