Intrinsic apoptosis in erythrocytes

Hi fellow cell biologists! - With a lack of mitochondria, can red blood cells perform intrinsic apoptosis and do they have another way of generating cytochrome c to attach to a CARD domain and assemble the apoptosome? Or are they dependent on killer lymphocytes to bind via the fas ligand and activat...

Topoisomerase DNA Replication :D

Will the Okazaki fragment in Topoisomerase DNA replication always be between the primase and the ligase protein complexes on the lagging strand? Are there any exceptions to this??

Thanks very much,

Billy :D

Phragmosome formation :D

Hi - Is a Phragmosome formed in S or G2? I have a feeling it's at the end of S. Also, At what point during the Prophase (after/before what) does it form Preprophase bands?

Thanks :D

Re: How much ATP a person consumes...?

Well, some glycoside hydrolase would break the bond - It would probably couple ATP hydrolysis or NADH/FADH hydrolyis and use a positive magnesium ion catalyst. I'd have to find out more info and do a Gibbs on that one. I have no idea regarding the exact energy consumption. Does anyone else?

Re: How much ATP a person consumes...?

It does require quite a bit of energy to break the alpha 1,4 glycosidic bond of glucose and fructose. Shouldn't that be taken into account?
