What would be the consequence of a mutation that prevents reversible phosphorylation in P-type ATPases?

• A. The ATPase would function normally but require more ATP for each transport cycle.
• B. The ATPase would transport ions in the opposite direction, causing cellular toxicity.
• C. The ATPase would be unable to transport ions, disrupting cellular ion balance.
• D. The ATPase would continuously transport ions, leading to cellular energy depletion.

Answer: (C)
