Function of an enzyme is to lower reaction's activation energy and to increase speed of a reaction, but to make it happen, enzyme and substrate must fit spatially. The shape of an enzyme is essential to make enzyme-substrate complex - if active site of an enzyme doesn't fit to substrate, there won't be a enzyme-catalised reaction.
Answer:
Anaerobic respiration does not need oxygen. It happens when there is not enough oxygen for aerobic respiration. ... 100m sprinters respire using anaerobic respiration in their race because their bodies do not take in enough oxygen during the race to carry out aerobic respiration.
Explanation:
Type O is the remainder after subtracting types A, B and AB.
so percentage of type O blood supply
= 100%-(28+15+10)%
= 100% - 53%
= 47%
Your blood also carries oxygen inhaled by the lungs. Your circulatory system delivers oxygen and nutrients to the other cells of your body then picks up any waste products created by these cells, including carbon dioxide, and delivers these waste products to the kidneys and lungs for disposal
