Consider the new definition of life. if you were to argue that a virus or a single mitochondria were, in fact, alive based on this definition, you would be ignoring the main tenet of
a. cell theory.
b. endosymbiosis.
c. nucleosynthesis.
d. natural selection.

Structures in cells that carry out specific functions.

Hey me with this one❤☺❤ how do you say that a cell also has a life span and death like an organism? give one example.

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)
