Question

How do enzymes catalyse endothermic reactions??

Answer 1

Answer:

A. enzymes form complexes with their substrates.

B. enzymes lower the activation energy for chemical reactions.

C. enzymes change the Keq for chemical reactions.

D. many enzymes change shape slightly when substrate binds.

E. reactions occur at the "active site" of enzymes, where a precise 3D orientation of amino acids is an important feature of catalysis.

Answer 2

Answer:

Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
