The theory of enzyme-substrate complex was established by Michaelis and Menton in 1913.According to their theory,enzyme combines with substrate to form enzyme-substrate complex.The transient complex has a lower energy of activation than that of substrate alone.This results in the acceleration of the reaction.The enzyme-substrate complex is broken down into enzyme and products of the reaction.

The different hypotheses of enzyme-substrate complex formation have been postulated.Early theory was postulated by Emil Fischer.According to this theory,the catalytic site of enzyme is preshaped to fit of the substrate.This hypothesis is called "lock and key" or rigid template.The next hypothesis has been proposed by Koshland in the late 1950s.The hypothesis was called "induced fit".Acccording to this theory,a catalytically active configuration of enzyme molecule and that of the active site can be induced only at the moment of attachment of the substate molecule,that is the substrate induces a conformotional change in the enzyme.
At the present time,model of "induced fit" is modified.Binding the substrate with the enzyme leads not only to the conformational change of the protein molecule,but also to a geometrical and electrontopographic rearrangement of the substrate molecules.
The modern "induced fit" hypothesis presumes the existence between the enzyme and the substrate of not only spatial or geometrical complementarity,but also electrostatic charge complementarity.
It is a thing constructed. It is the manner of construction of something and the arrangement of its parts. It is a complex anatomical part of a living thing.
no, a complex-complex sentence is just a complex sentence. there is no such thing as a complex-complex sentence.
Define processes on either end of communication. Define the types of messages. Define the syntax of messages. Define the meaning of any informational fields. Define how the messages are sent and the expected response. Define interaction with the next lower layer.
It explains the meaning of something. To define: To describe or outline the functional characteristics of a word or object.
They were unable to define the word properly. He used chalk to define the edges of the figure.
Define a complex sentence, your answer should follow
complex definition in tecnical writing means the word which is complex to define.
highly complex or complicated
Irrationa, perhaps. Imaginary or complex.

definition of simple media
In complex mode functions, modules, and procedures cannot operate. For a complex number z = x + yi, first define the absolute value. This would be |z| and is the distance from z to 0 in the complex plane.
It is the complex of all the attributes, behavioral,temperamental, and mental that characterize a unique individual.
You must remember that complex numbers need two parts - a real and an imaginar part, so you have to define fields for these parts. You also need to define methods at least for the basic operations, such as addition, subtraction, multiplication and division. You may also want to define methods for more advanced operations, such as trigonometric functions and the exponential function and natural logarithm, all of which have special definitions in the case of complex numbers.
Simple: I walked. Compound: I walked and my friend ran. Complex: While I walked to the store, my friend ran home to get more money.
