A number оf mutаtiоns hаve been described in G prоteins thаt have profound effects on their activity. For example, some mutations greatly increase the affinity of the G protein for GDP, making it very difficult for GDP to be exchanged for GTP. Other mutations prevent the hydrolysis of GTP to GDP. For each of the statements that describes a malfunction in cellular response, indicate the type of mutation that is responsible. ​ The MAP kinase pathway is continually activated, even in the absence of a signaling molecule.
