Question

Suppose you were graphing a type I motor unit vs. a type IIX motor unit on a force-velocity curve. What do you expect to see?

A. the type I motor unit and type IIx motor unit will demonstrate different velocities but similar forces
B. The type I motor unit and type IIx motor unit will have similar peak forces but the cooperativity of the curves will be higher in type IIx
C. the Type I motor unit and type IIx motor unit will demonstrate both different forces and velocities

Answer 1

When graphing a type I motor unit vs. a type IIX motor unit on a force-velocity curve, you would expect to see option C: the Type I motor unit and type IIx motor unit will demonstrate both different forces and velocities. Hence, C) is correct.

Step-by-step explanation:

When graphing a type I motor unit vs. a type IIX motor unit on a force-velocity curve, you would expect to see different forces and velocities for each type of motor unit.

Type I motor units are slower and generate less force, while type IIx motor units are faster and generate more force. The force-velocity curve shows that as force increases, velocity decreases.
