Endomembrane system -- not in prokaryotes
cytoskeleton -- a structural part of cytoplasm sometimes occurrent in prokaryotes
mitochondria -- not in prokaryotes
nucleus -- if this is a "membrane-bound" nucleus, then definitely not in prokaryotes
cytoplasm -- this is the fluid that houses everything in the cell membrane
flagella -- little "tail" for locomotion, so no
cilia -- similar to flagella, little feelers usually for locomotion
ribosomes -- these make protein using amino acids
chloroplasts -- not in prokaryotes
membrane -- just a casing surrounding a cell or organelle
organelles -- general word for the parts of a cell that perform various functions
cell membrane -- just the casing for the cell, not where genetic material's located
<span>nucleoid --- ding ding ding :-) this is it; a nucleoid is the genetic material which is loosely existing in the cytoplasm of a prokaryotic cell</span>
I say C. <span>it lowers the activation energy of a reaction in affects only very specific reactions. Correct me if I'm wrong tho...thank you ;)</span>
Those are both examples of ecological services!
Are the carbons in glucose ultimately used to make additional Krebs cycle intermediates
- The answer to the statement above is No, carbon loses 2 molecules of CO2 as the Krebs cycle moves up.
In the citric acid cycle, there are two carbons that belongs to the acetyl group of acetyl CoA. These two carbon are the released as carbon dioxide, one of main end products of cellular respiration via numbers of enzymatic reactions.
Conclusively, we can say that Co2 has 2 molecules shed off as Krebs cycle increases.
