K.C.S.E Biology Q & A - MODEL 2013PP1QN14
Name the three end products of anaerobic respiration in plants.
answers
K.C.S.E Biology Q & A - MODEL 2012PP1QN14
Name the type of respiration that is most efficient.
b) Give a reason for your answer in (a) above
answer
a)Aerobic respiration;
b)It releases more energy per unit mass;
K.C.S.E Biology Q & A - MODEL 2011PP1QN19
Write an equation that sum manses the process of aerobic respiration.
answers
​Glucose + Oxygen (enzyme)=Carbon IV oxide + water + energy;
C6 H12 06+602 (enzyme)= 6C02+6H20 + ATP
K.C.S.E Biology Q & A - MODEL 2011PP1QN10
Name the site of anaerobic respiration in a cell.
answer
K.C.S.E Biology Q & A - MODEL 2011PP1QN10
Give two differences in the products of anaerobic respiration between plants and animals.
answers
(i) Lactic acid in animals while in plants it is ethanol/alcohol;
(ii) No carbon IV oxide produced in anaerobic respiration in animals while anaerobic respiration in plants produces carbon IV oxide; K.C.S.E Biology Q & A - MODEL 2010PP2QN02
The diagram below shows blood circulation in a mammalian tissue.
(a) Name the parts labelled P and Q.
P . Q . (b) Name the substances that are: (i) required for respiration that move out of capillaries; (ii) removed from tissue cells as a result of respiration. (e) Explain how substances move from blood capillaries into the tissue cells. (d) Name one component of the blood that is not found in the part labelled P.
answers
(a)
P Tissue fluid/intercellular/interstitial fluid/space; Q Venule; (b) (i) Glucose, oxygen; (ii) Carbon (iv) Oxide, water; (c) Blood entering arteriole has a high pressure; the pressure forces water and small solute molecules in blood to go through capillary wall forming tissue fluids; nutrients/oxygen more into the tissue cells by diffusion; (d) Red Blood cells/proteins/platelets;

State two ways in which anaerobic respiration is applied in industries
answers
K.C.S.E Biology Q & A - MODEL 2009PP1QN24
Explain how the following factors determine the daily energy requirement in human:
(a) Age (b) Occupation (c) Sex
answers
(a) Young people are actively/ rapidly growing hence require more energy than older people
(b) Manual workers require more energy than secretary workers (c)Males are more muscular hence require more energy than females
