A&P Help

Golden_Clover · Feb 12, 2006

Was wondering if an A&P expert could help me with a few questions, first one is what would happen to a cell if it had no mitrochondria? How about no ribosomes? Thanks.

Well mitochondria are the "powerhouses" of the cell. Enzymes within the mitochondria carry out reactions in which oxygen is used to break down food. When food is broken down, energy is released. Most of this energy is lost as heat, but what energy is kept is ATP. ATP provideds energy for all cellular reactions in the body. Cells need a constant follow of ATP for all activities so without mitochondria your cell would not be able to function.

Ribosomes are the sites of protein synthesis. Without these, your body would be unable to put together protein strands, the building blocks for the entire body.

That's what I think they are anyway... Let me know if I am wrong.

Much luck studying...

Prokaryotic (bacteria and archea) cells don't have mitochondria, but have ribosomes. I guess without ribosomes there would be no cell/life whatsover.

If eukaryotic, the cell would die - technically it wouldn't really be a cell, anyway.

So the conclusion is that eukaryotes need both mitochondria and ribosomes, prokaryotes don't need mitochondria but ribosomes. This makes the ribosomes the most important because none would exist without them.

:clown: We are all turning into serious mad scientists :clown:

No mitochondria would mean that the cell created ATP through anaerobic respiration instead of aerobic respiration

What about if a cell had no Golgi apparatus, what would happen to it then?

I guess you would have no transportation of stuff from A to B and from B to C and so forth, just like if you would disable the distribution system of our goods....store shelfs would be empty, we wouldn't have fuel for our cars and we would go hungry and freeze. (and eventually die).
