An activated G protein can trigger all of the following except A)the opening of calcium ion channels in the membrane. B)the release of calcium ions from intracellular stores. C)a fall in cAMP levels. D)a rise in cAMP levels. E)an increase ATP production.

Question

Quizplus · Accepted Answer

Activated G proteins are involved in various cellular processes, including the opening of calcium ion channels (A), the release of calcium ions from intracellular stores (B), and changes in cAMP levels (C and D). However, they do not directly increase ATP production (E), as ATP production is primarily a function of cellular respiration and photosynthesis processes.
