Motor proteins such as as kinesin and dynein move along the cytoskeleton using the energy generataed from the hydrogen________, this phosphorylated nucleotide.
a. GDP
B. GTP
C. ATP
D. ADP
i THINK THE RIGHT ANSWER IS "C"
PLEASE CHECK
Since this is not my area of expertise, I searched Google under the key words "hydrogen ADP" to get these possible sources:

I hope this helps. Thanks for asking.
I think you are right. Read below.
Two main classes of microtubule motor proteins carry out ATP-dependent movement along microtubules (A. p. 952-953):
Kinesins are a large family of motor proteins, most of which walk along microtubules toward the plus end, away from the centrosome (MTOC).
Dyneins walk along microtubules toward the minus end (toward the centrosome).
In each case there is postulated to be a reaction cycle similar (but not identical) to that of myosin. Motility arises from conformational changes in the motor domain as ATP is bound and hydrolyzed, and products are released.
The correct answer is C. ATP.
Motor proteins such as kinesin and dynein move along the cytoskeleton using the energy generated from the hydrolysis of ATP (adenosine triphosphate) to ADP (adenosine diphosphate) and inorganic phosphate. ATP is a nucleotide that is commonly referred to as the 'energy currency' of the cell because it provides the energy needed for various cellular processes.
When ATP is hydrolyzed, it releases energy and is converted to ADP. This energy is used by motor proteins to power their movement along the cytoskeleton. Kinesin and dynein are both microtubule-based motor proteins that use ATP as the energy source for their movement.
In conclusion, motor proteins such as kinesin and dynein move along the cytoskeleton using the energy generated from the hydrolysis of ATP to ADP. So the correct answer is C. ATP.
