The question provided is not complete as it lacks the group of choices, however the group of choices are given as follows:
A. A contraction fails to occur because an action potential is not generated in the muscle cell.
B. A contraction fails to occur because this toxin directly prevents ion release from intracellular stores.
C. A contraction fails to occur because neurotransmitter release by the motor neuron is blocked at the neuromuscular junction.
D. A contraction fails to occur because this toxin prevents cross bridge formation and thereby directly prevents contraction.
E. C and D are both true
Answer:
The correct answer is option A : A contraction fails to occur because an action potential is not generated in the muscle cell.
Explanation:
A muscle contraction takes place when action potential bring to muscles by nerves, which is traveled with the help of motor neuron and imitated the muscle contraction.
Acetylcholine or Ach is a chemical messenger to bring the nerve impulses between a nerve and a muscle. If the receptor is block with applying toxin muscle will not contract as ACh will not be able to propagate the nerve impulse to the muscle so there will be no action potential.
The correct answer is option A : A contraction fails to occur because an action potential is not generated in the muscle cell.
Answer:
Explanation:
The concentration of the lipids will increase: phospholipids generated from CDP-DAG and a polar head group
The concentration of the lipids will decrease: phophosplipids generated from DAG and activated head groups "triacylglycerols"
The cell as a system contains the organelles sites of most cells active. Assembly line where workers do Endoplasmic Reticulum
The water will move by osmosis from the less-concentrated solution each is on the left to the more-concentrated solution. Hope this helped!
Answer:
B
Explanation:
When a Physician writes orders as ad lib, this means that the patient that the order is written for can have as much as they desire of the specific item that the Physician specifies in the order.
