In which one of the following points does the induced fit model of enzyme action differ from the lock and key model? * Substrate bind at the active site of the enzyme

Enzymes lower the energy of activation

During the reaction, an enzyme-substrate complex is formed

The shape of the substrate and active site are not complementary

The correct option is the last option

Explanation:

Firstly, one must understand that the first three options are generally properties of an enzyme and how an enzyme-substrate (ES) complex is formed during a reaction.

Enzymes bind to substrate in two major ways based on the shape of the active site of the enzyme; the lock and key model and the induced fit. The lock and key model is a model in which the active site ordinarily has the shape that can "accommodate"/bind to the substrate directly without any need for any change in the shape of the neither the active site nor the substrate during the process of formation of the enzyme-substrate complex. The induced-fit model is the model in which the active site of the enzyme and/or the substrate undergoes a change in shape as both of them draw close to each other because they ordinarily cannot fit/bind together; the shape of the active site and the substrate are not complementary.

NOTE: The active site is the part of the enzyme in which the substrate binds to.

increase soil erosion                                             reduce soil erosion

cattle grazing                                                         hydroseeding

                                                                                planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
