We have substrate enzyme system, we need to determine the effect on rate of reaction when substrate is added in different conditions.When additional substrate is added when substrate concentration is low:Substrate + enzyme = productwhen the substrate concentration is low and additional substrate is added, there are more particles to combine with enzyme and hence the reaction rate increases.When additional substrate is added when substrate concentration is high but not yet saturating:in this case there are already enough particles of substrate to combine with enzyme, there will be very minute increase in rate but it is negligible so we can say the reaction rate will not change.When substrate is added when enzyme is saturated with substrate:In this case all the enzymes are engaged and there is no effect of adding more substrate. Reaction rate will remain unchanged.Rate increase:additional substrate is added when substrate concentration is lowrate decrease:Rate is unchanged:additional substrate is added when substrate concentration is high but not yet saturatingsubstrate is added when enzyme is saturated with substrate
