The graph showing the concept of activation energy of enzyme is given below. Observe the graph and choose the correct option for M and N.

In the system shown below, $x(t)=\sin(t)u(t)$. In steady-state, the response $y(t)$ will be 
The time constant of the network shown in the figure is 
The parallel RLC circuit shown in the figure is in resonance. In this circuit, 
Catalysts of biological systems can be known as Enzymes. Enzymes helps us to perform the huge variety of biochemical reactions that encompass in life are all mediated by a series of activities.
Following are the properties of enzymes:
