Which of the following statements describes P-type ATPases is NOT correct?
- A P-type ATPases are cation transporters that are reversibly phosphorylated by ATP.
- B Phosphorylation of P-type ATPases forces a conformational change that moves cations across the membrane.
- C The $Na^+K^+$ ATPase is a symporter for $Na^+$ and $K^+$ ions in animal cells.

- E P-type ATPases are found only in eukaryotes.
思路引導 VIP
當我們在討論生物界中最基礎的能量驅動機制（例如調節細胞內礦物質濃度的離子幫浦）時，你認為這些維繫生命的分子機器，是只有在演化後期出現的複雜真核細胞中才看得到，還是從生命最原始的單細胞階段開始，就已經是所有細胞不可或缺的「標準配備」了呢？
