How do enzymes speed up biochemical reactions?

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. Many enzymes change shape when substrates bind.

Catalysts

Explanation:

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

i would say the prokaryotic cells the prokaryotic cells are less complex, are usually found only in unicellular organisms and have more limited capabilities than eukaryotic cells.
