Which of the following is responsible for transmitting an impulse across a synapse to another cell?
a. dendrites
b. axons
c. neurotransmitters
d. thresholds

The appropriate response is neurotransmitters. It is a compound substance that is discharged toward the finish of a nerve fiber by the entry of a nerve motivation and, by diffusing over the neural connection or intersection, makes the exchange of the drive another nerve fiber, a muscle fiber, or some other structure.

The option which is responsible for transmitting an impulse across a synapse to another cell is C. neurotransmitters. The name itself says it all - a neurotransmitter transmits impulses through neurons, and thus an effect is created in a person's brain and body. The other options do other things that are not mentioned in this question, so they aren't correct answers here.
