Question

A neurotransmitter ________________.

a. binds actin filaments, causing them to slide ( p p .2
b. di uses across a synaptic cleft from a neuron to a muscle cell
c. transports ATP across the synaptic cleft
d. breaks down acetylcholine at the synapse

Answer 1

b. di uses across a synaptic cleft from a neuron to a muscle cell.

Step-by-step explanation:

A neurotransmitter is di uses across a synaptic cleft from a neuron to a muscle cell. Neurotransmitters are chemicals which enable neurotransmission. In reaction to an impulse a motor neuron axon secretes a neurotransmitter and causes the muscle fiber to contract. It is a chemical messenger which passes on the signals across the chemical synapse.
