Document Summary

Small cells have more surface area and less volume, easier to supply the cell with nutrients. Large cells have small surface area but more volume, has problems to supply the volume fast enough: this lead to infolded membranes to increase surface area. Rna processed (transcripted) in the nucleus than leaves and gets (translated) by the ribosomes outside the nucleus into proteins. Explains why original transcript from dna may have altered; longer process before being translated (must go through nuclear membrane go through procedures, etc, before being translated into protein) Prokaryotes don"t have a nucleus and so the process takes less time; everything happens in the cytosol (cytoplasm) The endomembrane also consists of the smooth and rough endoplasmic reticulum. The cell provided 3-carbon pyruvate, the bacterium provided high energy atp through electorn carriers like nadh: this theory is supported by many observations.
