Which of the following statement about enzyme is correct ?
Options
- AThey alter the equilibrium constant of reactions
- BThey increase the activation energy of reactions
- CThey are specific in their action
- DThey are consumed in the reaction
Correct answer
C. They are specific in their action
Step-by-step solution
Enzymes are biological catalysts that speed up the rate of biochemical reactions without being consumed in the process. They do not alter the equilibrium constant of a reaction; they only help attain equilibrium faster. They work by lowering the activation energy of the reaction, not increasing it. Enzymes are highly specific in their action, meaning each enzyme typically catalyzes only one specific reaction or acts on a specific substrate. Thus, the statement that they are specific in their action is correct. Answ
