1.	Which of the following graphs correctly indicates the reaction in presence (indicated bt +) and absence (indicated as -) of an enzyme ?A. P,Q,R and S represent the same reaction carried out in the presence of enzyme, and low temperature, respectively.B. Q and S represent the same reaction carried out at high and low temperatures, respoectively.C. R and S represent the same reaction carried out in the presence and absence of catlyst, respectively.D. P and R represent the same reaction carried out in the absence and presence of enzyme, respectively.
Answer» Correct Answer - D Standard free energy represents the energy available to do work at standard temperature. Activation energy represents the energy required to start a reaction. The enzyme works by lowering down the activation energy.
