Kinases and phosphatases turn proteins on and off through the following mechanism: A. making or breaking disulfide bonds, resulting in changes in protein conformation or interaction with other proteins B. adding and removing phosphate groups, resulting in changes in protein conformation or interaction with other proteins C. adding or hydrolyzing GTP, resulting in changes in protein conformation or interaction with other proteins D. Adding or removing ubiquitin, resulting in changes in protein conformation or interaction with other proteins

Which of the following does not describe a typical cellular response to signaling molecules? a. activation of enzymes within the cell b. change in the function of structural proteins, which determine cell shape c. alteration of levels of certain proteins in the cell by changing the level of gene expression d. change in a gene sequence that encodes a particular protein e. All of the above are examples of cellular responses.
