the secret-hiding behind erythrocyte...

assalammualaikum..
wah dh lme la jugak xpost kat blog ni..
ntah dh byk spider web dh..hihihi

actually now...i'm still 'shocking' state
i'm new to all these subjects anatomy, physiology n biochemistry yet in this so early period i hav to read so many things...
too many things to understand-too many things to remember
plus when the lecturer ask in class u hav to answer whatever the question is though u don't understand even a single thing in the previous~
if u r not prepare wif the aswer the solution is simple........
u just walk out n u'll be marked as absence
well that's the fact about this uni but still i hav to endure it for more thn 4 years..
nywy, its ok..
i'm sure there r so many advantages behind the system..eh rilly??hope so XD

eh actually i wann to reveal bout erythrocyte...
here is the question:
the red blood cell has no nucleus, no mitichoria n no ribosome..but still it cn live for 120 days and carry out its normal activities.HOW???
the answer is:
RBC depend mainly on glucose metabolism for its energy supply(the other is brain cell). glucose is easily transported across its cell membrane via facilitated diffusion. although RBC has no mitochondria but it has cytoplasmic enzymes for metabolizing glucose n other substances for utilization for oxygen. but the metabolizing system becomes progressively less active with time, so it limits the life span of RBC...
