Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Identify the true statement(s).
A
Dynein always moves toward the plasma membrane.
B
Dynein is responsible for movement of microvilli.
C
Myosin motors move along actin proteins.
D
Myosin motors move along actin proteins and Dynein always moves toward the plasma membrane.
Explanation: 

Detailed explanation-1: -As discussed later, the motor activity of myosin moves its head groups along the actin filament in the direction of the plus end. This movement slides the actin filaments from both sides of the sarcomere toward the M line, shortening the sarcomere and resulting in muscle contraction.

Detailed explanation-2: -Which of the following is true of actin and myosin filaments? Explanation: Actin and myosin filaments are essential contractile elements found in muscle cells. They are essential because they conduct muscle contraction.
