Cell Communication Quiz

What are the three general ways cells communicate?

• Direct Contact, Local Signaling, Long-distance signaling

• Reception, Transduction, Response

• Paracrine signaling, Synaptic signaling, Endocrine signaling

• G protein coupled receptors, Ion channels, Ligand gated ion channels

Which type of cell junctions allow signaling substances and other material to pass freely between adjacent animal cells?

• Gap junctions

• Plasmodesmata

• G protein coupled receptors

• Ligand gated ion channels

What is the term for the release of chemical messages that travel a short distance through the extracellular fluid to cause a response in a target cell?

• Paracrine signaling

• Synaptic signaling

• Endocrine signaling

• Transduction

Which type of signaling occurs in animal nervous systems where neurons secrete neurotransmitters that diffuse across the synaptic cleft to reach the target cell?

• Paracrine signaling

• Synaptic signaling

• Endocrine signaling

• Transduction

What is the main way animals and plants use for long distance signaling?

• Gap junctions

• Plasmodesmata

• Endocrine signaling

• Ligand gated ion channels

Which type of receptor is involved in signal pathways and binds to polar, water-soluble ligands?

• G protein coupled receptors

• Ion channels

• Intracellular receptors

• Ligand gated ion channels

Which type of receptor is found in the cytoplasm or nucleus of target cells and binds to ligands that can pass through the plasma membrane?

• G protein coupled receptors

• Ion channels

• Intracellular receptors

• Ligand gated ion channels

What is the term for the conversion of an extracellular signal to an intracellular signal that will bring about a cellular response?

• Reception

• Transduction

• Response

• Signal transduction pathway

During transduction, the signal is amplified with the help of:

• G protein coupled receptors

• Ion channels

• Second messengers

• Intracellular receptors

What is the final stage of cell signaling where the signal is converted to a response that will alter a cellular process?

• Reception

• Transduction

• Response

• Signal transduction pathway
