Question
In Chapter 8, we saw that ATP is the currency of the cell, powering almost all the work carried out in a typical cell. In almost all eukaryotes and aerobic prokaryotes, the majority of this ATP is synthesized from the flow of stored hydrogen ions (protons) in the form of a proton gradient. This week’s forum will explore the universality of proton gradients and provide insight into the role they may have played in the origin of life itself and why, despite their incredible biochemical virtuosity, prokaryotes have failed to develop the complex morphology (multicellularity) observed for eukaryotic cells . Read the article Why Are Cells Powered by Proton Gradients, and answer the questions that follow. ----> LINK ; https://www.nature.com/scitable/topicpage/why-are-cells-powered-by-proton-gradients-14373960
4. Speculating is a fun part of science. Many of the hypotheses put forth in this paper are highly speculative. For example, little data exists to support the hydrothermal vent origin of proton gradients. Based on our class discussions, either propose another possible origin for proton gradients, or propose a question on a point or aspect of the origin that you find unclear or confusing.
Explanation / Answer
Devolepment of proton pump was a part of the evolution As organsim devoleed from simple to complex and acquired the membrane in thier structure,which is preoimary for the generation of a gardient .To add up to these a lot of comped enzymes are messed up for the process which complex organism have.The generation of proton motive force and the couoled ATP production made our life so easy .
