Enzymes consist of a protein part and a prosthetic group connected by weak bonds. During activity,these weak bonds are separated. This process is known as:

$A$ mathematical explanation of enzyme action on substrate was formulated by

What is ribozyme?

The figure shows the conversion of substrate into product by an enzyme. In which one of the four options are the components of the reaction labelled $a, b, c, \& \ d$ identified correctly?
$(i)$ Potential energy
$(ii)$ Transition state
$(iii)$ Activation energy with enzyme
$(iv)$ Activation energy without enzyme

The number of active sites in an allosteric enzyme is:

The reaction given below is catalysed by oxidoreductases between two substrates $A$ and $A'$. Complete the reaction: $A \text{ reduced} + A' \text{ oxidised} \longrightarrow$ ?
