[Campbell Biology P.1116] The cone snail's venom blocks information transfer by neurons. Base... | Practice Question

The cone snail's venom blocks information transfer by neurons. Based on the information provided, which of the following processes would be most directly inhibited by this venom?

  • A: The synthesis of new neurons in the nervous system.
  • B: The reception of sensory input by dendrites.
  • C: The transmission of signals from one neuron to another across a synapse.
  • D: The maintenance of the resting potential by ion pumps.

Explanation

The text states that the cone snail venom's lethal nature is its "ability to block information transfer by neurons." The section "How does a neuron transmit information?" further explains that neurons "transmit the information to other cells via specialized junctions called synapses." Therefore, blocking information transfer most directly points to inhibition of synaptic transmission.
