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.

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.

d. organisms have cells with different shapes and functions.
