Question

Chemicals which are released at the synaptic junction are called

• A. hormones
• B. neurotransmitters
• C. enzymes
• D. lymph

Answer 1

The correct option is B neurotransmitters

Chemicals which are released at the synaptic junction are called neurotransmitters. Synapse is junction present between two neurons. Neurotransmitters are released in the synaptic junction and are involved in the transmission of impulses from one neuron to the next. They are present in the synaptic vesicles at axon terminals. Whereas, hormones are non-nutrient chemicals which act as intercellular messengers and are produced in trace amounts.

Enzymes are biocatalysts that enhance the rate of a biochemical reaction.

Lymph is a colourless fluid containing specialised lymphocytes which are responsible for the immune response of the body.
