Synthesize the effects of cholera toxin on G protein signaling and its physiological consequences.

• A. Cholera toxin causes G protein to be stuck in its active form, leading to excessive cAMP production and water loss, resulting in dehydration.
• B. Cholera toxin enhances G protein degradation, leading to decreased signaling.
• C. Cholera toxin has no effect on G protein signaling.
• D. Cholera toxin inhibits G protein activity, reducing cAMP production and water retention.

Answer: (A)
