K.C.S.E Biology Q & A - MODEL 2017PP1QN02

Below are diagrams of a cell organelle obtained from different organs of an animal

​(a) (i) For each organelle state an organ in the urinary system where it is likely to be found. 
F 
G
(ii) Give a reason for your answers in (a) (i) on page 2. 
(b) Name the part of the chloroplast where the following reactions occur:
(i) Carbon(IV) oxide fixation 
(ii) Photolysis 

answers

(a) (i) F - Kidney; 
G - Bladder/Ureter/Urethra; 
ii) Kidney - active re-absorption of solutes requires more energy; organelle F has more cristae for attachment of more respiratory
enzymes producing more energy; Bladder/ureter/urethra does not require as much energy/organelle G has less number of cristae hence fewer respiratory
enzymes attached/less energy produced; 
(b) i) Stroma;
ii) Grana/granurn;
