Summarize what you have learned about different ways to change enzyme activity. complete a fishbone diagram to show how different factors cause an increase or decrease in enzyme activity.

Many enzymes help in cellular respiration. Using the figure to the right, explain the difference between this reaction with and without an enzyme. You must use the following terms in your answer; active site, induced fit, substrate and activation 1. Enzyme Action Without enzyme Activation energy without enzyme energy. With enzyme Activation energy with enzyme Reactants: Glucose + 0, Overall energy released during reaction Products: co, + H,0 Do NOT answer both questions 2 and 3. Choose only ONE to answer in the space provided. 2. The enzyme catalase is a polypeptide. Would you expect this enzyme to move through the cell membrane via simple diffusion? Explain your answer and provide a possible solution if catalase can't move across a membrane. 3. It is important for humans to make sure they consume small amounts of minerals (e.g. magnesium oxide or zinc oxide) in their food or in a supplement of some sort. Explain the value that some minerals play in assisting with many of our body's…

What are the steps for an enzyme to create a product in order:  The energy of activation is lowered so the reaction can happen quicker. Substrate attaches to the active site. The product is created and released from the active site. The energy of activation is lowered so the reaction can happen slower. A specific substrate attaches to the active site.

Classify each phrase as describing an enzyme, an active site, or a substrate. Enzyme may be a phosphate group a protein containing an active site a substance that the enzyme acts upon a biological catalyst Active site Answer Bank Substrate a specific enzyme location that binds with the substrate

Identify the missing words in the below description. Word bank: gain, oxidation, release, reduction (use 3 words to answer the questions only) Question: Energy is often transferred via oxidation-reduction reaction (redox reaction) in a living system. molecule, whereas is the gain of electrons for a molecule. Redox reactions are usually accompanied by A B of energy. Oxidation Reduction A oxidized B reduced is the removal of electrons from a

A biologist investigating enzyme function plotted the activity of a particular enzyme (y-axis) vs pH (x-axis).  Experiment A was performed at 30 oC, experiment B at 10 oC and experiment C at 100 oC.  Experiments A, B, and C all used the same type of enzyme, they simple tested the enzyme's activity at different temperatures.  Using your knowledge of enzyme activity, answer the questions based on the results shown in the graph. (Answer question B) Graph included B.  Why is there no hill in the middle of line C?

Explain how enzymes work to speed up reactions

explain how measuring the effect of temperature on enzyme activity will be different from measuring the effect of enzyme concentration on enzyme activity.

Describe how an enzyme and substrate combine to facilitate a reaction.

Describe how enzymes function; be sure to include information about energy use in your answer.
