- a) What is the Steady State assumption; how does steady state differ from equilibrium? b) Transition state; what are two ways that enzymes can decrease the transition state energy?arrow_forwarda) Describe a specific chemical reaction that occurs within the human body and state the name of the enzyme involved, the substrate(s) of the reaction, and the specific product(s) formed. b) Enzymes are not used up in chemical reactions. So, what exactly does an enzyme do? In your answer you should refer to activation energy. c) Explain what is meant by the induced fit action of an enzyme, referring to the role of the active site, and to the activation energy of an enzyme-catalysed reaction.arrow_forwardHow do enzymes speed up reactions? What is the active site of an enzyme and what does it do? If an enzyme speeds up the forward reaction, then what does it do to the reverse reaction?arrow_forward
- How does an enzyme lower the activation energy of a reaction? Draw a graph showing the difference of activation energy of a reaction with and without the help of an enzyme.arrow_forwardBen is studying an enzyme-catalyzed reaction. In the reaction, H+ ions are formed. He found that after a specific time, the reaction stopped, even though there was still a lot of substrate available in the mixture. a) Propose a hypothesis to explain why the reaction stopped.arrow_forwardWhat is the difference between and endergonic reaction and an exergonic reaction? What is an example of an endergonic reaction that takes place in a cell?arrow_forward
- Why does increasing enzyme concentration promote enzyme activity?arrow_forwardHow does the act of a spontaneous reaction occurring allow for the non-spontaneous reaction to also occur? Does one release energy and the other absorb it, and how?arrow_forward“Enzyme increases the rate of a reaction by lowering the activation energy. In doing so, it also changes the equilibrium of that reaction.” Do you agree/disagree with this statement? And why?arrow_forward
