well i ur right =)
that was pretty stupid of me Marz katy for the contentes of the lysosome did u put just ER or also golgi ...
and what did u say for the binding sit s of 02 c02 and c0
i am absolutuly sure it was H plus ions nd CO
I chose cellulose, water and glycogen! Since glycogen has OH which consists of a hydrogen bond, and I dont remember reading anywhere that haemoglobin has hydrogen bonds and I dont recommend saying that you are sure of the answers when the mark scheme is not released yet because you never know and you might get someone over stressed when they had the right answer all alongwhat about the question which said where hydrogen bonds are necessary
cellulose water haemoglobin and glycogen
well no1 wants to stress any1..every comes here to share what dey rote and the reason y dey rote to be sure...if u tink its wrong dont come to these discussions=) http://www.bio.davidson.edu/Courses/Molbio/MolStudents/spring2010/Hua/Hemoglobin.html......chk ds out dat haemoglobin has hydrogen bond...and u show me wer its ritten gycogen has hydrogen bond...il be glad if u can show meI chose cellulose, water and glycogen!

Katy We had CO C02 H ions and Hc03 HC03 makes no sense right? ... H ions come from the disscociation of the carbonic acid which came from the dissolve of cabon dioxide... So carbon monoxide is not what causes oxygen to dissociate per se but it is the hydrogen ions. As we seen carbon monoxide has a higher affinity and binds to the esame part as oxygen forming carboxyhaemoglobin.... This test seemed easy but it was kinda hard
Yeah me too i picked endocytosiswhich process is the movement of molecules that are too large to diffuse IN through a cell surface membrane
choices were active transport , endocytosis , facilitated diffusion and osmosis
i picked endocytosis
what was the answer to that question which showed a structure of a molecule and then said what it could this structure be ?
glucose , ribose and deoxyribose....
By the way the one with the bypass it was the first one i think To improve oxygenation of the heart muscle and by pass it ....
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
