Ans1) Lock and Key model and Induced Fit model are two models which describe the binding process between enzyme and substrate.
Lock and Key Model:
This model assumes high degree of complementarity between the binding site of the enzyme and its substrate just like a lock and its key.
It is proposed by Emil Fisher in 1894.
Induced Fit Model:
This model states that binding of the substrate causes a conformational change in the enzyme that results in a complementary fit between the enzyme and the substrate.
Difference between both the models:
According to Lock and Key model, the substrate and the binding site of the enzyme are complementary to each other before the substrate binds to the active site.
But according to Induced fit model, the active site forms a complementary shape to the substrate only after the substrate has been bound.
explain the induced-fit model of enzyme action, and how this differe from the "Lock-&-key" model NOA...
The lock and key model and the induced fit model are two models of enzyme action explaining both the specificity and the catalytic activity of enzymes. Indicate whether cach statement is part of the lock and key model, the induced fit model, or is common to both models. Lock and key model Induced fit model Common to both models Answer Bank The substrate binds to the enzyme at the active site, forming an enzyme-substrate complex The substrate binds to the...

Bio 121 I need to make (yeast fermentation) lab report. This is the lab experiment and results: This is a guide to making the lab report: General Biology BIO121 Yeast Fermentation Lab Introduction Organisms stay alive by the utilization of energy through metabolism. The energy acquiring pathways in photosynthesis convert radiant energy from the sun into the chemical bond energy of carbohydrates. This photosynthetic process is limited to the producers or autotrophs, which include plants, photosynthetic bacteria and some protists....
