Lesson 3.3 - Enzymes and Activation Energy

Question 1

An _____ energy barrier must be overcome for any reaction to proceed. _____ energy initiates the breaking of bond in reactants as they reach the _____ state.

Answer 1

An activation energy barrier must be overcome for any reaction to proceed. Activation energy initiates the breaking of bond in reactants as they reach the transition state.

Question 2

The spontaneity of a reaction does not predict how _____ it will occur. Some spontaneous reactions are very slow.

Answer 2

The spontaneity of a reaction does not predict how fast it will occur. Some spontaneous reactions are very slow.

Question 3

Enzymes speed up reactions by lowering the _____ energy of the reaction.

Answer 3

Enzymes speed up reactions by lowering the activation energy of the reaction.

Question 4

Enzymes can bring reactants to the _____ state by one of three mechanisms: bringing the two reactants closer together, changing the charged environment around the substrate, or bending or distorting the substrate.

Answer 4

Enzymes can bring reactants to the transition state by one of three mechanisms: bringing the two reactants closer together, changing the charged environment around the substrate, or bending or distorting the substrate.

Question 5

Enzymes _____ used in many industrial processes.

Answer 5

Enzymes are used in many industrial processes.

Sorry that one was kind of stupid but you just need to know this information. Sorry! Good luck studying.
