Cell Signaling

It allows cells to perform various cellular activities, coordinate, and interact with other cells. All cells of an organism receive signals from their environments and respond accordingly. Even the unicellular eukaryotes receive signals secreted by other cells and respond. In the case of yeast, mating takes place by signaling between the yeast cells. Communication by cell signaling in a multicellular organism has become a vast and important part of various fields of biology.

Explain the experimental procedure used byLoewenstein to determine the size of molecules that can passthrough gap-junction channels.
Which of the following statements about ion channels is INCORRECT? Like carrier proteins, most channel proteins are specific regarding which molecules are allowed to pass. Channel proteins can have open or closed configurations. Unlike carrier proteins, some channel proteins are engaged in active transport of solutes. Channel proteins are used extensively in nerve cells, in which they are responsible for transduction of electrical signals. Compared to carrier proteins, channel proteins allow much faster transport.

Uniporters and ion channels support facilitated transport across cellular membranes. Although both are examples of facilitated transport, the rates of ion movement via an ion channel are roughly 104 - to 105 -fold faster than the rates of molecule movement via a uniporter.

Some antibiotics act as carriers that bind an ion on one side of a membrane, diffuse through the membrane, and release the ion on the other side. The conductance of a lipid-bilayer membrane containing a carrier antibiotic decreased abruptly when the temperature was lowered from 40°C to 36° C. In contrast, there was little change in conductance of the same bilayer membrane when it contained a channel-forming antibiotic. Why?
The model of an ion channel is composed of five polypeptide subunits. What are they?
