5. What is the function of phosphatases in signal transduction processes? Amplify the transduction signal so it affects multiple transducers Amplify the second messengers such as CAMP Inactivate protein kinases and turn off the signal transduction Prevent a protein kinase from being reused when there is another extracellular signal Move the phosphate group of the transduction pathway to the next molecule of a series
In the cAMP signal transduction pathway, a protein kinase is activated. What happens next G protein is activated. cAMP is converted to ATP. The protein kinase activates a cellular response. GDP is replaced by GTP. Adenylyl cyclase is activated.

6. Lipid-soluble signaling molecules, such as testosterone, cross the plasma membranes of all cells A) by diffusion but affect only target cells because only target cells retain the appropriate DNA segments. B) by diffusion but affect only target cells because only target cells have the intracellular receptors for testosterone. C) through hydrophilic channels of transmembrane proteins but affect only target cells because only target cells retain the appropriate DNA segments. D) through hydrophilic channels of transmembrane proteins but affect only...
You are studying a signal transduction pathway. Activation of your pathway results in activation of transcription of a gene that you are studying. In addition, activation of the signal transduction pathway results in phosphorylation of a number of effector proteins. Which of the following is most likely an effector protein of your signal transduction pathway that regulates transcription of your gene? A. An activator protein B. A coactivator protein C. A HAT D. A basal factor E. RNAPII
help with 7-10 Question 7 1 pts Phosphorylation of kinases in one location can result in activation, while phosphorylation in another location on the same protein can result in deactivation of the enzyme. True False Question 8 2 pts Dephosphorylation, or removal of a phosphate group, is accomplished with the help of a both kinases and phosphatases neither kinases not phosphatases phosphatase kinase Question 9 1 pts Select all of the following that act as second messengers.

The gene “C” codes for the membrane-associated protein C, responsible for signal transduction. A mutant allele of this gene, Cm, encodes a malfunctioning C protein, which has the same size as the wild type and associates with the plasma membrane like the wild type, but it has no function in signal. With respect to the expression of the C proteins, the wild-type allele is: A. codominant to the Cm allele. B. dominant to the Cm allele. C. haploinsufficient. D. incompletely...
