activity is affected by temperature and pH.Enzymes speed up chemical reactions by lowering the activation energy of the reaction.Enzymes have a unique three dimensional shape, and an active site which is has a specific shape that is complementary to a specific substrate.Enzymes are specific in ...
Almost all biochemical reaction in living cells requires the participation of enzymes, biological catalysts which speed up reactions by lowering the activation energy without becoming altered during the reaction. That is why the reactions proceed toward equilibrium more rapidly than the uncatalyzed ...
3. Which of the following statements about enzymes or their function is true? Enzymes do not alter the overall change in free energy for a reaction Enzymes are proteins whose three-dimensional form is key to their function Enzymes speed up reactions by lowering activation energy All of the...

Figure 2. An energy profile for the glucose reaction. An enzyme (green) enhances the reaction rate by lowering the amount of activation energy required to boost the reactants to the transition state at the summit of the energy barrier. Every biochemical reaction involves both bond breaking and...
Enzymes are biological catalysts that work by speeding up the rate of reactions in cells and organisms. Enzymes can work by lowering the activation energy needed for a reaction to begin or by speeding up the reaction itself. Answer and Explanation: ...

Enzymes are made up of proteins. Enzymes act as a catalyst in living organisms. A catalyst is a substance that speeds up chemical reactions. SO, CELL METABOLISM Enzymes Definition Catalysts Proteins that speed up chemical reactions by lowering the energy of activation. ...
Enzymesare biological catalysts. These are commonly proteins but also include RNA (ribozymes) molecules that catalyze chemical reactions by lowering the activation energy of a reaction. These are known to speed up the rate of a reaction millions of times faster than the reaction without enzymes. ...
