Question
Choose one best answer.
The following are all false about how both myosin and kinesin motors move along filaments, EXCEPT for this ONE TRUE statement:
Both are ATPases, with ATP-binding to the motor head domain what simultaneously causes the motor to undergo a "power stroke".
adenine nucleotide exchange
Both are ATPases, with the ATP hydrolysis cycle within the motor tail domains resulting in protein conformational changes that drive motor movement.
Both are ATPases, with ATP-binding to a motor head domain triggering the release of a motor head from cytoskeletal binding.
Both are GTPases, with distinct successive protein conformational changes associated with GTP hydrolysis and then GDP and/or Pi release from the motor head domains.
A.Both are ATPases, with ATP-binding to the motor head domain what simultaneously causes the motor to undergo a "power stroke".
B.adenine nucleotide exchange
C.Both are ATPases, with the ATP hydrolysis cycle within the motor tail domains resulting in protein conformational changes that drive motor movement.
D.Both are ATPases, with ATP-binding to a motor head domain triggering the release of a motor head from cytoskeletal binding.
E.Both are GTPases, with distinct successive protein conformational changes associated with GTP hydrolysis and then GDP and/or Pi release from the motor head domains.
Explanation / Answer
D Both the ATPases with ATP binding to a motor hear domain triggering the release of Motor head from the cytoskeletal binding.
Myosin and kinesin are the motor proteins involves in the muscle contraction an relaxation used ATP energy source.
Rest of answers are false
