Refer to the Biochemistry in Focus section of your text for this chapter to answer this question. Which of the following mutations in muscle glycogen phosphorylase could result in a condition similar to McArdle disease?

a. Protein phosphatase 1 cannot dephosphorylate the mutant muscle glycogen phosphorylase.
b. Mutant muscle glycogen phosphorylase is unable to bind to glucose 6-phosphate.
c. Mutant muscle glycogen phosphorylase is unable to bind to AMP.
d. Mutant muscle glycogen phosphorylase is unable to convert to the b form.

Clara wrote the following hypothesis for an experiment about acidophilic bacteria. bacteria cells will stop dividing in a basic (alkaline) environment because of the high ph. which statement is the best way to restate the hypothesis so that it is more specific? growing acidophilic bacteria in some environments will cause the cells to stop dividing because of ph. if the ph of their environment is changed, acidophilic bacterial cell division will be affected. if the environment of acidophilic bacterial cells becomes alkaline, the bacteria will stop dividing. the more alkaline an environment, the less cell division will occur in bacteria.
