Quiz for Chapter 11 & 12
1. Paracrine signaling
A) involves secreting cells acting on nearby target cells by discharging a local regulator into the extracellular fluid.
B) requires nerve cells to release a neurotransmitter into the synapse.
C) occurs only in paracrine yeast cells.
D) has been found in plants but not animals.
E) involves mating factors attaching to target cells and causing production of new paracrine cells. 2. Which of the following is true of synaptic signaling and hormonal signaling?
A) Hormonal signaling occurs in animals only.
B) Hormonal signaling is important between cells that are at greater distances apart than in synaptic signaling.
C) Both act on target cells by a G-protein-signaling pathway.
D) Only A and B are true.
E) A , B, and C are true.
3. From the perspective of the cell receiving the message, the three stages of cell signaling are
A) the paracrine, local, and synaptic stages.
B) signal reception, signal transduction, and cellular response
C) signal reception, nucleus disintegration, and new cell generation.
D) the alpha, beta, and gamma stages.
E) signal reception, cellular response, and cell division. 4. When a cell releases a signal molecule into the environment and a number of cells in the immediate vicinity respond, this type of signaling is
