A titratable group is in the active site of an enzyme and must be protonated for the enzyme to function. Assume that the group has a pKa of 6.5 and that the activity is proportional to the fraction of molecules in the protonated state. Which of the following are true?
1. At pH 9.0 close to 100% of the enzyme molecules are active.
2. At pH 9.0 close to 100% of the enzyme molecules are inactive.
3. At pH 6.5 the enyzme is 50% active.
4. At pH 6.8 the enzyme is 66.6% inactive.5. At pH 7.2 there are about 5 inactive enzymes for every active enzyme.

Listed in the item bank are some key terms and expressions associated with the categories seen in the venn diagram. to find out more information about items, some have more details available when you click on them. drag and drop each item onto the proper area of the diagram. if an item describes more than one category, be sure to place it in the overlapping space. viruses are tiny infectious pathogens that cause many different diseases, such as polio, and the flu. though they are similar to one celled organisms in some ways, in many ways they are very different. use the venn diagram below to show the similarities and differences between viruses and living organisms.
