The enzyme phosphorylase kinase catalyzes a modification of glycogen phosphorylase that controls its activity. How does phosphorylase kinase modify glycogen phosphorylase?

a. adenylation, which transfers an adenosine from ATP to the phosphorylase enzyme direct AMP

b. binding to glycogen phosphorylase after hydrolysis phosphorylation, which transfers a phosphate from ATP to the phosphorylase enzyme

c. a conformational change driven by the energy released when ATP is hydrolyzed

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.

If bacteria are much too small to see, what is one reason why can we see colonies in the petri dishes that have plenty of food to eat after only a few days?
