what celluar function is negatively impacted by an increase in cell size?

Since a cell's volume increases significantly more than its surface area as it enlarges, the membrane cannot supply all the requirements of the cytoplasm past a certain point.  This is why cell size is generally limited.  So the function you are referring to is diffusion, the movement of material into/out of the cytoplasm.

Neoplasm (abnormal growth), Atrophy (decrease in size), Hypertrophy (increase in size) and Hyperplasia (increase in number) are things the body goes through in its fight for Homeostasis.  So yes, I think they help the body adapt but that's not necessarily always a good thing because sometimes the adaptation can be more than the body can handle while maintaining homeostasis.

The fibers just get bigger, or become hypertrophied.  These larger fibers will also have more mitochondria for energy, store more glycogen, have more microfilaments and myofibrils in the fiber, and increased connective tissue between the fibers.

hi, i work 4 a book company, and 1 of our regular books is on cell and molecular biology, if you email me, i can probably give you an answer on exactly what ur question is.

The cell is the structural and functional unit of all living organisms, and is sometimes called the "building block of life." Some organisms, such as bacteria, are unicellular, consisting of a single cell. Other organisms, such as humans, are multicellular, (humans have an estimated 100 trillion or 1014 cells; a typical cell size is 10 µm, a typical cell mass 1 nanogram).\n\nThe cell theory, first developed in 1839 by Schleiden and Schwann, states that all organisms are composed of one or more cells; all cells come from preexisting cells; all vital functions of an organism occur within cells, and cells contain the hereditary information necessary for regulating cell functions and for transmitting information to the next generation of cells.\n\nThe word cell comes from the Latin cella, a small room. The name was chosen by Robert Hooke when he compared the cork cells he saw to the small rooms monks lived in.\n\nAll cells, whether prokaryotic or eukaryotic, have a membrane, which envelopes the cell, separates its interior from its environment, regulates what moves in and out, and maintains the electric potential of the cell. Inside the membrane, a salty cytoplasm takes up most of the cell volume. All cells possess DNA, the hereditary material of genes, and RNA, containing the information necessary to build various proteins such as enzymes, the cell's primary machinery. There are also other kinds of biomolecules in cells.

Inside our cells -it is a blind, mute and deaf world of roaming/floating molecules! Molecules (including the macromolecules like proteins) wonder almost aimless but can have influence on each other -like, breaking or joining others. But these interactions have to specific. The specific contact and the influence on each other is possible only due to the compatibility in the physico-chemical features on their surfaces, which are directly dependent on the structure.\n\nIt is the proteins that carry out most of the functions in cells. Hence, protein structure is very important for cell function. Because actin is such a basic structural protein and cytochalasin B can interact with it (and affect it), their interactions seem influence activities in different cells and events like fertilization and immune functions. You can look up for literature on this aspect.\n\nI am quoting one abstract from the NCBI's PubMed database (Journal -Biochim Biophys Acta. 1980 Dec 16;626(2):494-500.; PMID: 6894243)of research work by  Maruyama K, Hartwig JH &Stossel TP.:\n\nCytochalasin B and the structure of actin gels. II. Further evidence for the splitting of F-actin by cytochalasin B.\nCytochalasin B decreased the flow birefringence and s20,w and increased the extinction angle of actin filaments in salt solutions favoring polymerization of the protein. These changes occurred without a detectable increase in the equilibrium actin monomer concentration determined by a radioassay. These results complement earlier observations indicating that cytochalasin B shortens actin filaments without net depolymerization. Analyzed in terms of Flory's classical network theory, this shortening accounts for the marked effect of cytochalasin B in dissolving the gel structure of F-actin crosslinked by actin-binding protein concentrations near the critical concentration for incipient gelation. Cytochalasin B decreased the annealing rate of low concentrations of actin filament fragments prepared by sonic disruption. The result is consistent with the idea that cytochalasin B binds to the ends of actin filaments, and may explain how cytochalasin B causes filament shortening.

Cells have different shape to allow them to work better. For example, the alveoli cells are flat and big in surface, these features helps in gas exchange.

Well, a cell is closest to a sphere. As you increase the size of a sphere, the surface area increases less quickly as the volume does. When the volume of a cell increases, more toxins are made that have to be shipped out of the cell, and more nutrients and oxygen have to make it inside the cell. The surface area controls how much can be exchanged, so if the SA doesn't increase as fast as the V, then we see a limiting factor to cell growth.

You need to give more information about the shape to get a definitive answer.  If the cell were cubical, then the volume increases 1000 times if all three sides increase 10 times in length.

the cell would not be able to grow or repair it self...the cell would most likely die.

I suppose that two processes are to blame:\na) The accumulation of extracellular material (extracellular matrix)\nb) The accumulation of senescent (old, non-replicating) cells that are less able to maintain a stable environment\n\nThis is not an "official", research-quality response. I'm just talking out of my head but I think I may be right.

When a cell becomes 'worn out', the body replicates the cell so that the cells function can continue uninterrupted.  \n\nCancer occurs when a cell tries to replicate itself and makes a mistake when transcribing the genetic encoding to the new cell.  The resulting new cell is mutated, and is no longer able to accomplish the function the cell is designed for.  \n\nThe next time it replicates, the mutation is duplicated, and frequently exacerbated, during the duplication process.  \n\nEach time this occurs, the resulting product of the attempt to replicate becomes more and more mutated, and less and less able to accomplish the function of the cell.\n\nThe cells then begin to clump - since the cell is attempting to carry out its assigned function and finds itself unable to do so.  This triggers the mechanism which causes the cell to replicate; so that the resulting product of replication will be able to carry out the cells primary function.  \n\nWhen the replication is incapable of accomplishing the primary function of the cell, it triggers another replication.  The clump grows larger and larger, and eventually you have a tumor.
