Which one of the following statements holds true for the induced-fit model?
a. once the enzyme binds to the specific substrate molecule, no structural changes can occur in the active site of the enzyme.
b. once the enzyme binds to the specific substrate molecule, structural changes can occur in the active site to accomodate the product.
c. once the enzyme binds to a specific substrate molecule, subtle structure changes occur in the active site, which are reverted when the reaction is over.

The phlogiston theory in the 17th century attempted to explain burning. the theory stated that combustable objects contained a material called phlogiston, a substance without mass, color, odor, etc. after objects burned, the objects were dephlogistonated and were then in their true form. the phlogiston theory was accepted until the 18th century, when lavoisier proved that combustion requires a gas that has mass. phlogiston is considered a) to be scientific knowledge b) not to be scientific knowledge c) to be proven by scientific method d) to be accepted in the modern scientific community
