Question
Chapter 34.1, Problem 1BC
Summary Introduction
To write:
The difference between the sensory receptor and the cell surface receptors.
Introduction:
Receptors are chemical structures, composed of protein, that receive and transduce signals that may be integrated into biological systems. These signals are typically chemical messengers, which bind to a receptor, they cause some form of cellular/tissue response.

In most neurons, membrane depolarization leads to the opening of voltage-dependent ion channels, generation of an action potential, and, ultimately, an influx of Ca2+, which causes release of neurotransmitter at the axon terminus. Devise a cellular strategy by which hyperpolarization in rod cells could produce excitation of the visual pathway and passage of visual signals to the brain. (Hint: The neuronal signaling pathway in higher organisms consists of a series of neurons that relay information to the brain. The signal released by one neuron can be either excitatory or inhibitory to the following, postsynaptic neuron.)
Which of the following statements is false?
Question 11 options:
a)
Nucleotides and amino acids can act as extracellular signal molecules.
b)
Some signal molecules can bind directly to intracellular proteins that bind DNA and regulate gene transcription.
c)
Some signal molecules are transmembrane proteins.
d)
Dissolved gases such as nitric oxide (NO) can act as signal molecules, but because they cannot interact with proteins they must act by affecting membrane lipids.
The tetanus toxin tetanospasmin blocks release of the neurotransmitter (GABA) that inhibits motor neurons and decreases muscle contraction. This causes persistence of the signal to contract and the resulting violent muscle contraction known as tetanic spasm. Compare the sustained contraction of muscle cells in rigor mortis with muscle contraction caused by the action of tetanospasmin on motor neurons.
Describe experiments using marker molecules that have been done to elucidate important properties of (1) tight junctions and (2) gap junctions, and propose one additional experiment you could do with each junction to gain a greater understanding of that junction's properties.
