The difference between active and passive cellular transport is that active transport requires energy for the ions and molecules to move across the cell membrane whereas passive cellular transport does not an energy input.
Answer:
Number of molecules= 9.34 * 6.022*10^23 = 5.6245*10^24 molecules.
Explanation:
Answer:
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.
