How is "proxduces" represented in a chemical reaction? What cellular organelle coneains catalase and is present in all plant and animal organs S. What did measuring the bubble column heights in all the experimental procedures indicate? What purpose did the tube containing water and hydrogen peroxide serve in the catalase activity experimental procedure? 7. What ond describes the loss of an enzyme's original shape and ability of its to function? 8. 9, what did the negative control tube lack when the effect of enzyme concentration was What happens to enzyme activity if the temperature increases slightly studied? 10. If cells produce more catalase, will there be more or less water and oxygen producesd from the breakdown of hydrogen peroxide by catalase? 11. What word describes the pH at which the speed of a reaction involving an enzyme occur best? 12. What do changes in pH (too low or too high) do to an enzyme that reduce its activity? 13. In the Experimental Procedure on the effect of pH on enzyme activity, which tube -.. . contained water with an acidic pH? 14.

These people may take a commercial product called Lactaid to prevent digestive upset when consuming dairy prodacts What is in Lactaid that helps these people avoid those symptoms? Explain how this relates to what you learned about the specificity of enzymes for substrates in this lab. 16. High-grade fevers (in humans, 103°F or higher) are of concern, and medical care should be obtained. Esxplain why, based on your understanding of enzyme function. 0 Laboratory & How Enzymen FuExplanation / Answer
ans1. Produces are represented on the right side of an equation.
these are represented after a arrow pointing towards product.
for e.g when A reacts with B to give C as a product. We can write this equation like
A + B -------> C
here C is the product or produced.
ans. 2 In a biochemical reaction, Enzymes bind with chemical reactant called substrate.
There may be one or more substrate for each type of enzyme, depending on the particular chemical reaction.
Hence, Substrate can be regarded as a REACTANT in a chemical reaction.
ans3 In biology , the active site is the region of an enzyme where substrate molecules bind and undergo chemical reaction.
ans4. Peroxisomes contains enzyme catalase , which decomposes hydrogen peroxide either by converting it to water or by using it to oxidize another organic compound.
