Chemical reactions
Factors affecting the following reactions
(a) The ability to sustain aerobic exercise is limited by the amount of haemoglobin in the blood :Reactant (Haemoglobin) concentration.
(b) Non-starch polysaccharides are large complex carbohydrates, and an important source of fibre. Their chemical energy content is similar to other carbohydrates like sucrose, but they do not undergo respiration via by human digestion : Chemical nature of reactant. As non-starch polysccarides do not break into smaller units easily, they cannot undergo respiration via human digestion.
(c) Potato is made edible by cooking it : Temperature.
(d) Digestion is enhanced by chewing our food : Presence of catalyst. The catalyst present in saliva help digest food when chewing.
Kinetics Broadly speaking, the factors that influence chemical reaction rates may be summarised as follows. Chemical...
