Defense Mechanism

Circumstances influence and compel people to behave in a certain way. One such behavior is a defense mechanism. It is employed by people to escape from unpleasant circumstances, thoughts and actions. Defense mechanisms are, thus, psychological strategies that help to avert and avoid unwanted feelings such as guilt or shame and situations such as threat and danger.

Gap junctions and tunneling nanotubes are two distinct types of direct intracellular
communication. In comparing and contrasting gap junctions and tunneling
nanotubes, which of the following statements is true?
gap junctions provide a portal for small molecules, proteins and small organelles

pass between cells
typically, there are only two gap junctions that exist between adjacent cells that
are communicating via this mechanism; on the other hand, there are many
tunneling nanotubes between communicating cells
both gap junctions and tunneling nanotubes can pass small molecules between
cells

What would happen in each of the following cases where something related to intracellular transport is altered? Assume in each case that the protein involved is a soluble protein, not a membrane protein. State where each protein would be located and explain each of your answers. You change the hydrophobic amino acids in an ER signal sequence into negatively charged amino acids. You discover a protein that has both an ER signal sequence and a nuclear localization sequence. The ER signal sequence is at the N-terminus of the protein, and the nuclear localization sequence is located in the middle of the protein.
As we age our skin becomes thin and easily tears. One potential reason to explain would be if adjacent cells within the skin lose the ability to attach to each other strongly. Another reason could be that cells lose the ability to attach strongly to the extracellular matrix. Compare and contrast these membrane functions and suggest which proteins might be “lost” as we age to cause the loss of attachment function in each scenario
