Who really cares about the electron transport chain?

Post by bionut720 » Thu May 03, 2007 3:09 am

All I hear my classmates talk about is the significant role of the electron transport chain in producing a proton gradient and the NADPH and ATP. Couldnt all these processes occur without the electron transport chain (abbreviated etc)

No. That's why the process is so important.

I thought the mitochondrion was that the main thing in the production of the ATP so why does the etc matter?

umm, but the mitochondrion is where all those etcs take place, producing ATP in the process.

Actually, cyanide is so lethal to vertebrates because it interfers with the electron transport chain...

As far as creating ATP in mito, u tell me where the energy comes from without a ETC. Do you think ATP just gets created instantly by dumping a couple of ADP and P together.

Theres no NADPH in mitochondria? but there is NADPH in animal cells, it is not just in plants...
isnt it an important reducing agent? im confused

My fault, I was thinking of the oxidative phos pathway with NADH. NADPH is in the pentose phosphate pathway.
