I am a high school student really excited to participate in the life long adventure of learning biology....:)

I am a big fan of all those people who never give up no matter what !

I love to white water raft, teach,read books, help my friends, and think new things !

ADVENTUROUS NERD :) but am completely bored of homework....

comment What does “kcal/mol” mean when speaking of enzyme catalysis?
@TMOTTM yes I agree. Tunnel is a bit too much.

comment What does “kcal/mol” mean when speaking of enzyme catalysis?
Shouldn't we say - energy barrier of the reaction rather than that of the enzyme (as TMOTTM has written in the question) ?

After reading ur comment above I think I will have to search vitrectomy from a reliable source. See from a good textbook maybe.

comment Does our eyeball increase in size as we grow?
Ok to settle the debate I asked an ophthalmologist - he says that after vitrectomy the eye ball decreases in size. No replacement happens.

@llan ok will take care in the future ! Though I should tell you that I have read the same thing in Tortora and Derrickson principles of anatomy and physiology.

comment Does our eyeball increase in size as we grow?
@llan Interesting question ! Though I don't know how that is replenished I can quote two lines from wikipedia which furthers the mystery - It is produced by cells in the non-pigmented portion of the ciliary body deriven from embryonic mesenchyme cells which then degenerate after birth and Unlike the fluid in the frontal parts of the eye (aqueous humour) which is continuously replenished, the gel in the vitreous chamber is stagnant. Therefore, if blood, cells or other byproducts of inflammation get into the vitreous, they will remain there unless removed surgically.

@llan The ciliary body makes more AQUEOUS humor not vitreous. I have read that NO new vitreous humor is made, it is present in fixed amounts.

comment Does our eyeball increase in size as we grow?
@llan Thanks! If I assume that growth does continue, then how is new vitreous humor made ? Is the growth of the eye, after birth, so negligible that there is no need to add new vitreous humor ?
