B) The enzyme has active sites where the substrate binds with the enzyme to form a complex. When the substrate binds to the active site, an induced fit is formed where the enzyme changes its shape in order to better serve the substrate and lower the activation energy of the reaction
Answer:
The greenhouse and enhanced greenhouse effects refer to the return of approximately <u>80</u> percent and greater than <u>80</u> percent of the heat radiated by Earth.
Explanation:
During natural greenhouse effect :
. Solar radiation reaches the earth
. Re-radiation of heat occurs
. Less re-emitted heat
. More heath escapes into space
Hence the greenhouse effect refers to return of 80% of heat radiated by Earth.
While during Human Enhanced Greenhouse effect :
. Solar radiation reaches earth
. Re-radiation of heat occurs
. More re-emitted heat
. Less heat escapes into space
Hence the enhanced greenhouse effect refers to return of more than 80% of heat radiated by Earth .
