<prompt> Which of the following is NOT a feature of coenzyme?It has high molecular weightIt combines loosely with enzyme molecules.Mostly belong to vitamin B complex groupIt is heat stable  <response>: Salient features of coenzymes The protein pa of the enzyme gives the necessary 3-D Infrastructure for chemical reaction, but the group is transferred from or accepted by the co-enzyme Essential for the biological activity of the enzyme Low molecular weight organic substance is heat stable Combine loosely with the enzyme molecules, The enzyme and co-enzyme can be separated easily by dialysis Inside the body, when the reaction is completed, the co-enzyme Is released from the apo-enzyme and can bind to another enzyme molecule One molecule of the co-enzyme is able to conve a large number of substrate molecules with the help of an enzyme Most of them are derivatives of vitamin B complex substances.
