The first ideas about substrate binding to the active site of an enzyme were based on a lock and key model, with the active site being the keyhole and the substrate being the key. When the right substrate entered the active site, catalysis occurred because the substrate was perfectly complementary to the active site.

Oct 26, 2014 · • Which of the following statements about enzymes or their function is true? A. Enzymes do not alter the overall change in free energy for a reaction B. Enzymes are proteins whose three-dimensional form is key to their function C. Enzymes speed up reactions by lowering activation energy D. All of the above 61. The purpose of the lab was to test out osmosis. No, my results did not exactly support my hypothesis because the bag with 0.0 M of sucrose should have a change of mass of 0, but instead, there was still a change in mass (4.9%). What can be concluded from this lab though, is water does follow higher concentration of "salts" for balance purposes.
