Document Summary

Most enzmes = protein (some are rna) An enzymes functionality depends on its abilty to maintan its shape - can be affected by temperature and ph. If the environment is too acidic or basic, it can denature, change the shape and can not function. Inhibitors - substancce that binds to enzyme and decreases its activty. Competive - competes with substrate for the active site. Non-competitve - binds to enzyme at allosteric (any other) site and causes the shape to change, making the enzyme unable to bind the substrate. Non-protein organic molecule that assists proteins in functioning. Enzyme"s purpose = speed up the reaction. An enzyme alters the activaon energy of a reaction, needed to initiate a chemical reaction. Pockets or clefts for substrate binding; where the substrate ts precisely. Is a precise t of substrate into the active site - shape is very important as the site is designed speci cally for the molecule being broken down.

QUESTION 10

If you can drink milk as an adult, it means that you have inherited a mutation in the promoter of your lactase gene (the gene that encodes the enzyme you need to break down lactose). Predict the effect of this mutation:

		The mutation changes the number of domains in the enzyme, which makes it work more efficiently
		The mutation changes the amino acid sequence of the lactase protein
		The mutation increases the number of copies of the lactase gene that will be found in your genome
		The mutation changes whether the lactase sequence is found in an intron or exon
		The mutation affects the expression of the lactase gene

QUESTION 11

A competitive inhibitor is decreasing the activity of an enzyme. Predict the effect of adding more substrate to the reaction.

		The substrate will increase the reaction rate by competing with the inhibitor for the active site
		The reaction rate will not change unless the inhibitor can be removed
		The enzyme adjusts its shape so that the substrate, but NOT the competitive inhibitor, can bind
		The substrate will bind to the competitive inhibitor and block its ability to bind to the enzyme

What is the benefit of using BOTH the lac activator and the lac repressor to control gene expression?

		The activator can override the inhibition of the lac operon by the repressor
		The repressor can control the enhancer, while the activator can control the promoter
		When neither the lac activator or repressor is present, expression of the lac operon is too high
