    s05: 14th) you can see that at B the graph is not steepest. the gradient is low. its not the optimum temperature. k.e of enzyme and substrate will get low at this point. whereas A its not far from the start of reaction so at this pooint bonds will be formed for enzyme substrate complex to be...

    no.6 i don't get it. how do we calculate this? q.16 i think its B because all the enzyme gets used up. the independent variable is substrate concentration which we are altering , dependent is enzyme , so at w n x the reaction rate becomes zero as all enzyme molecules are being used up.

    boy are you kidding me :D you can see that the de-oxygenated blood has just entered into the alveolus at A. there will be almost no oxygen at A. it can't be D because blood is leaving from the alveoli. gaseous exchange took place. oxygen concentration is highest at D

    maybe because you are not thinking hard on this one. ;) see the problem here is that the person who has antibodies for blood group A already can't go thru a transfusion of blood. so the people who don't have antibodies for blood group A are blood group A and AB. see the table. people with these...

    see the questions asks that when will be the water potentials get same. this is only possible when the initial length to final length ratio becomes 1. this happens at C .45 mol/dm cube

    the only confusing thing is that the lung volume has to do something with todal capacity or breathing rate??? i think no. :/ in A : if we multiply number of breaths per minutes with tidal volume we get 8.4.( this is the amount of oxygen absorbed in one minute. ) in B : 9 in C: 8 in D : 6.8 B...

    4) the wall of the alveoli is about 1 cm distance with the blood capillary around in the image. so 10,000 / 2500 = 4 closer to B 12)D , because enzyme is usually inactive at low temperatures. the rate of reaction doubles after every 10 degree rise in temperature. A is very steep, B shows no...

    03 ppr 1) see rough endoplasmic reticulum is concentrated with ribosomes around and r.e.r makes ribosomes which are the sites for protein sysnthesis so it will rapidly take amino acids. 18) we need to have tRNA's with the same base sequence or anticodons which will get match with the code on...
