Question

Match the experimental technique with information obtained.

A) 3D visualization of motor movement along a filament
B) kinesin 1 step size
C) whether a microtubule or microfilament motor protein is responsible for cell activity
D) how much force is generated by a motor protein

21) optical laser trapping (tweezers)
22) Atomic Force Microscopy (AFM)
23) fluorescent spot tracking
24) drug inhibition of ATPase activity

Answer 1

To match techniques with information: A) Use fluorescent spot tracking for 3D visualization of motor movement; B) Optical laser trapping measures kinesin step size; C) Drug inhibition identifies the responsible motor protein; and D) Atomic Force Microscopy quantifies the force generated by motor proteins.

Step-by-step explanation:

To match the experimental technique with the information obtained:

• A) 3D visualization of motor movement along a filament - Match with fluorescent spot tracking because this technique allows us to visualize and track motor proteins like kinesin as they move along microtubule tracks within cells.
• B) kinesin 1 step size - Match with optical laser trapping (tweezers) because this technique can measure the tiny distances moved by motor proteins such as kinesin with each step.
• C) whether a microtubule or microfilament motor protein is responsible for cell activity - Match with drug inhibition of ATPase activity since this method can inhibit motor proteins like dynein and kinesin to determine their role in cell activity.
• D) how much force is generated by a motor protein - Match with Atomic Force Microscopy (AFM) as this technique can measure the forces produced by motor proteins when they interact with cytoskeletal elements.
