Why are so many paets of the cell convoluted or folded?

increased surface area means increased area for reaction to occur. \n\nincreasing surface area in all cell organelles means that there is an increase in rate of reaction\n\nmeaning that cells work better in general

G'day Joanne F,\n\nThank you for your question.\n\nIt is essential if you are studying medicine to have a good understanding of how cells and tissues work. It is also useful to know how particular cells such as blood cells work.\n\nRegards

it happens , the partial perassure of o2 is less in cells than in hemaglobin so it diffusses in to cells frm hemoglbin

from original cell 2 from those (daughter cells)  they each split again which results in 4 cells...hope this helps...the question is hard to understand

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.

store information about the cell. its mostly hereditary.

For example, the lungs and small intestine contains microvilli.  Another example, the brain and intestine also are folded.

The first and most important thing is for the surface area to volume ratio. The smaller the ratio, the more efficient the cell.\n\nAlso, cells are building blocks of something bigger. If we had huge cells, imagine how big we'd have to be in order to hold trillions of them. ;)\n\nThat's about it in the nutshell.

that's really rare but it has happened before.  It has to do with the chromosomes and how they are activated and crossed over and everything...it's complicated.

Mitochondria are bounded by a double membrane. \nEach of these membranes is a phospholipid bilayer with embedded proteins. \nThe outermost membrane is smooth while the inner membrane has many folds.  \nThe folds enhance the productivity of cellular respiration by increasing the available surface area. \nThe double membranes divide the mitochondrion into two distinct parts: the intermembrane space and the mitochondrial matrix. The intermembrane space is the narrow part between the two membranes while the mitochondrial matrix is the part enclosed by the innermost membrane. \nSeveral of the steps in cellular respiration occur in the matrix due to its high concentration of enzymes. \nMitochondria are semiautonomous in that they can divide and grow to make more of themselves. They also have their own DNA and ribosomes.

There are numerous proteins embedded in the lipid bilayer of the cell membrane; some, like adrenergic receptors and porins (channels things move through), perforate the membrane; others protrude out one part, not another.  Others, like the G-proteins and the enzymes that phosphorlate and dephosphorylate other membrane proteins, stay pretty much entirely in the membrane.\nMany of the proteins, such as receptors and porins, move fairly freely; others, particularly the proteins that cause adherence between cells, are fixed in place.\nI guess the best answer is that the arrangement of the proteins in the cell membrane is complex, and for many proteins, ever changing, but for others, static.  It's not nearly as simple as it looks.  For instance, in modeling the large membrane proteins, the cell membrane is effectively a gas in two of three dimensions, and a solid in the third...  Go figure.

They are eukaryotic, multicellular, and in the kingdom Animalia. They come from mammals (you and me) and so that means they have an membrane enclosed nucleus, as opposed to prokaryotic cells that don't have a nucleus.  They are multicellular b/c all animals are.  And the kindom Animalia applies cheek cells as well. :)

Suface Area and Transport Distance. I Strongly Suspect the Reason Prokaryotic/Eukaryotic Cells Are the Size they Are is Because of Evolutionary Optimization by Natural Selection.

Hi Anita. I believe the best answer is D) histology.\n\nAnatomy is a much broader area than this.\nCell biology is more concerned with the internal functions of the cell.\nChemistry is not directly involved with how cells are arranged.\nPhysiology is a much broader area of study.\n\nHope this is helpful for you.  Best wishes.

the cell dividing force lol. theres no such force. it's a spontaneous occurence
