- Which of the following aspects of catalysis by enzymes can NOT be explained by the Fischer Lock and Key Hypothesis? Enzymes will lower the activation energy barrier for reaction. Enzymes will specifically recognize their substrates. Appropriate substrates will bind to the enzyme to form a Michaelis complex. Enzymes have an "active site" where appropriate substrates will be bound. Two of the above cannot be explained by the Fischer "Lock and Key" Hypothesis.arrow_forwardBriefly explain how enzymes decrease the activation energy of biochemical reactions.arrow_forwardHow can ATP hydrolysis be used to drive an endergonic reaction via reaction coupling?arrow_forward
