Question

what are some examples of signaling molecules involved in cellular communication?
chromosomes, genes, and dna.
antibodies, antigens, and lymphocytes.
amino acids, fatty acids, and glucose.
enzymes, receptors, and transporters.
hormones, neurotransmitters, cytokines, and growth factors.

Explanation:

Hormones (e.g., insulin), neurotransmitters (e.g., dopamine), cytokines (e.g., interleukins), and growth factors (e.g., epidermal growth factor) are all molecules that play crucial roles in cellular communication. Hormones are chemical messengers transported in the bloodstream. Neurotransmitters transmit signals across synapses. Cytokines are involved in immune responses and cell signaling. Growth factors regulate cell growth and division.

Answer:

Hormones, neurotransmitters, cytokines, and growth factors.
