A. Membrane transport is Sodium potassium pump;Requires ATP is ✓;Is a cotransporter is ✗;Transports ions is ✓
B. Membrane transport is Exocytosis;Requires ATP is ✓;Is a cotransporter is ✗;Transports ions is ✗
C. Membrane transport is Sodium dependent glucose cotransporters;Requires ATP is ✓;Is a cotransporter is ✓;Transports ions is ✓
D. Membrane transport is Facilitated diffusion;Requires ATP is ✗;Is a cotransporter is ✗;Transports ions is ✓
参考答案: A
本题详细解析:
The sodium-potassium pump does require ATP to function, as it actively transports sodium and potassium ions. However, it is also a special type of cotransporter known as an antiporter, as it pumps two different substances, sodium and potassium ions, at the same time, using the same protein pump, but in opposite directions. Choice A is therefore the correct answer. Choices B, C and D are all incorrect answers.
