eukaryotic cell is fed glucose and it releases carbon dioxid

eukaryotic cell is fed glucose, and it releases carbon dioxide. How many membranes do the carbons atoms involved cross?

Solution

Three membranes possibly which are as follows.

1 CELLMEMBRANE,,,,,

In cytosol glycolysis occurs

2) MITOCHONDRIAL INNER MEMBRANE

3) MITOCHONDRIAL OUTER MEMBRANE

glycolysis products have to enter in the stroma of mitochondria for krebs cycle to occur, thus has to pass 2 membrane inner and outer belonging to mitochondria....

Hope it helps ......feel free to discuss ....i would be glad to learn along with u ...... Regards
