Results from our forumcan anyone help me answer these biology questions?... - what are the compenets inside a cholorplast? - what are the types of macromolecules in living organisms? - know types of linkages (peptide, ester, glycosidic etc.) - what are enantiomers? - be able to match up cell structure with its function - what is organic chemistry based on? - how would ...

Re: Krebs Cycle question... then acts as a nucleophile toward bound oxaloacetate. Water--freely available from the environment--preferentially hydrolyzes the resulting thioester (citryl-CoA) so the net reaction is the transfer of an acetate group to oxaloacetate removing the CoA in the process. The thiol activates in two ...

Re: membrane permeability - let's make it clear!... is always a small quantity of unbound hormone that can diffuse inside the cell to bind a nuclear receptor. No, they are not. You are thinking cholesterol, which is transported into the cell by receptor mediated endocytosis. The main difference is this: when you are talking cholesterol, you need ...

Ingesting Cholsterolyeap. There are other physiology books out there. It matters less what you read, if you read one at all. BTW, cholesterol is sometimes present in the diet esterified with fatty acids. If that is the case, the ester bond is first broken and then the cholesterol is absorbed.

Cellular Steroidogenesis... but these proteine are enzymes which will be sent to mitochondria and SER for steroidogenesis. Steroidogenesis is started when lipid droplets (ester cholesterol) are transported into mitochondria to undergo side-chain cleavage into pregnenolone. The next step will be called as "steroid ...
