the graph represents three activation every profiles for chemical reaction the graph represents three activation every profiles for chemical reaction the graph represents three activation every profiles for chemical reaction Lab Section:b This assignment should be completed before entering lab. This assignment is beginning of the lab session. Use BioFlix Tutorial for Chapter 8 to complete th 1 The graph presents thre activation energy profiles for a chemical reaction (the hydrolysis of sucrose): an uncatalyzed reaction, and the same reaction catalyzed by two different enzymes Activation Energy Uncatalyzed Enzyme A Enzyme 8 Reaction Progress Rank these by reaction rate, as measured by the rate of product formation per unit time, from lowest reaction rate to highest reaction rate. a. Reaction catalyzed with enzyme A, b. Reaction catalyzed with enzyme B, c. Uncatalyzed reaction Enzyme #1 (lowest reaction rate): #2: Speeifie- Active site Denatured- Catalyst Cemplex- #3 (highest reaction rate): 2. Fill in the blank using the word bank provided. a. An enzyme is Denahaxed when it loses its native conformation and its biological b. An enzyme is considered a c. An enzyme is considered Secse because of its ability to recognize the shape of d. When properly aligned, the enzyme and substrate form an enzyme-substrate (ES) e. A substrate binds to an enzyme at the Ache sik where the reaction occurs. f. In a catalyzed reaction a reactant is often called a Sunshnte activity without being used up. a particular molecule. because it speeds up chemical reactions 35Explanation / Answer
1. Energy that is needed by a substrate to reach transition state is called activation energy. It is the energy barrier for substrate to convert in product.
Lower the activation energy = higher the rate of reaction
In case of enzyme B energy requirment is lowest (see the y axis of the graph) so reaction rate is highest. Then enzyme A and highest energy is required by uncatalyzed.
Ans is : uncatalyzed >enzyme A > enzyme B
