Cellular Respiration Questions

Post by Liquidpyro » Tue Jan 03, 2006 6:03 pm

I am doing a biology packet and have a few questions that I cant seem to figure out...

The chapter is on cellular respiration, and I cant figure out why the structure of a mitochondrion is well adapted for the activities it carries out...

Another question I will take directly form the packet::: In the krebs cycle what molecule acquires most of the energy that is released by the oxidation of acetyl CoA and how many of thes e molecules are produced during each turn of the Cycle?

I only have 40 minutes left before I have to turn this in, and I am conpletely stuck...

Cmon 15 views and no replys I am desperate!!!
Please Help Me :)
Any help would be greatly appreciated. Thanks!!!

Here is a great site that can help u understand the importance of mitochondria and appreciate its creative structural design.

and heres my attempt to explain ur latter questions.

Pyruvate dehydrogenase catalyzes pyruvate to form acetyl-CoA. Basically Nad+ to NADH and CO2 is released and if u look up a diagram of the krebs cycle u will see that 2 carbon atoms remain and they link up to form acetyl CoA. This is high energy bond and acetate is now in its activated form.
