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:
Scientists repeats the steps in cycle mode and in order to be sure about the results he/she chosen.
Option A would be the appropriate one as we know the common formula of carbs is CH2O we can get C10H20O10 by that formule! :)
The closer the light is to the plant the rate of photosynthesis will be greater compared to when the light is further away from the plant the rate of photosynthesis will be lower.
Fatigue in skeletal muscles typically develops during repeated shortening contractions, as during walking or running. However, most experimental fatigue studies have analysed isometric muscle contractions, were the muscle generates force at a constant length.
