|
Identify all features relating to Enzymes
|
|
Enzymes cannot be easily inactivated
|
|
|
Enzymes accelerate the rate of a reaction, and the reaction is reversible
|
|
|
Enzymes are regulated by cofactors
|
|
|
Enzymes catalyse only biological reactions
|
Explanation:
Detailed explanation-1: -Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction. The increased rate is the same in both the forward and reverse directions, since both must pass through the same transition state.
Detailed explanation-2: -Essentially, enzymes are biological catalysts. Like other catalysts, enzymes are not reactants in the reactions they control.
Detailed explanation-3: -All biological reactions within human cells depend on enzymes. Their power as catalysts enables biological reactions to occur usually in milliseconds.
