darks and SohaibButt You guys are welcome any time!! If you have any questions ask me anytime and good luck for your exams
We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

Thanks a lot brodarks and SohaibButt You guys are welcome any time!! If you have any questions ask me anytime and good luck for your exams
The atrio ventricular valves and the semilunar valves are both closed only there is a high pressure in the ventricles (during ventricular systole) but not high enough to open the semilunar valves and pump blood through the aorta (Between point 1 and 2) AND when the pressure in the ventricle decreases (Ventricular diastole) but the pressure is. still high enough to keep the semilunar valves closed (between point 3 and 4) . just find the time between these points and add them up!Can someone please explain this question?
Got it. Thank you so much.The atrio ventricular valves and the semilunar valves are both closed only there is a high pressure in the ventricles (during ventricular systole) but not high enough to open the semilunar valves and pump blood through the aorta (Between point 1 and 2) AND when the pressure in the ventricle decreases (Ventricular diastole) but the pressure is. still high enough to keep the semilunar valves closed (between point 3 and 4) . just find the time between these points and add them up!
Even I couldnt solve this ques, this video helped me A LOT! http://highered.mheducation.com/sit...22/animation__the_cardiac_cycle__quiz_2_.html
Hope that helps
both b and d will help in maximise uptake of oxygen as blood lows through capillaries in the lungs so they are wrongc. oxyhaemoglobin formation increases the capacity of red blood cells to transport oxygen.
ber, varia
does this answer make senseguys i need some help regarding these questions:
1. What does not help to maximise uptake of oxygen as blood lows through capillaries in the lungs?
a. dissociation of carbon dioxide from carboxyhaemoglobin allows more haemoglobin to available for oxygen binding.
b. each haemoglobin molecule can temporarily bind to eight oxygen atoms.
c. oxyhaemoglobin formation increases the capacity of red blood cells to transport oxygen.
d. the binding of the first oxygen molecule to haemoglobin increases the molecule's affinity for binding other oxygen molecules.

Q 07 from october/november, variant 12 and like this on Q 12 may/june 2015, variant 12
Q 23 from may/june 2015, variant 12
i chose c which was wrong i don't know why, but how a is the answer? and can you explain me answers to other questions as well? these: Q 15 and 31 from may/june 2016, variant 11both b and d will help in maximise uptake of oxygen as blood lows through capillaries in the lungs so they are wrong
i think it could be either a or c
oxy hemoglobin formation does not increase Capacity of RBCs to transport o2 but it only increase Affinity of Hb to o2 /cooperative binding so it could be the answer
there is a phenomenon known as Haldane effect which explains the answeri chose c which was wrong i don't know why, but how a is the answer? and can you explain me answers to other questions as well? these: Q 15 and 31 from may/june 2016, variant 11

Why is option A incorrect? When they have specifically mentioned cell may be 'unable to produce' an enzyme..?
I understand that build up of lipids suggests that this is a hydrolytic enzyme and so lysosomes is the answer.
But I don't get why golgi apparatus is invalid?
shoot i didn't see that coming! lol thanks by the way it is solved..Guys, I think you all are misreading the statement. Took me long enough but we're really dumb if none of us noticed this (I'm referring to shahzaib ihsan's question above).
30 What does not help to maximise uptake of oxygen as blood flows through capillaries in the
lungs?
A Dissociation of carbon dioxide from carboxyhaemoglobin allows more haemoglobin to be
available for oxygen binding.
B Each haemoglobin molecule can temporarily bind to eight oxygen atoms.
C Oxyhaemoglobin formation increases the capacity of red blood cells to transport oxygen.
D The binding of the first oxygen molecule to haemoglobin increases the molecule’s affinity for
binding other oxygen molecules.
It's A because.......
CARBOXYhaemoglobin.
*facepalm*
Carbon dioxide doesn't form carboxyhaemoglobin, carbon MONOXIDE does. Carbon dioxide forms CARBAMINOhaemoglobin. That's why the option is incorrect.
I think being such little geniuses here on xtremepapers (no sarcasm) sometimes we all end up overthinking.
in prophase chromosomes recoil and condense and the centriole divide to reach at the oppsite pole of the cell. hope this helpsCould anyone help me out here?
B looks correct, and D looks correct,
So why is D the answer? And not B?

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.
