Question

Which of the following proteins is/are NOT (an) ABC transporter(s)?

A. ATP-binding cassette transporter A
B. ATP-binding cassette transporter B
C. ATP-binding cassette transporter C
D. Non-ATP-binding cassette transporter X

Answer 1

ATP-binding cassette transporter A, ATP-binding cassette transporter B, and ATP-binding cassette transporter C are ABC transporters, while Non-ATP-binding cassette transporter X is not.

Step-by-step explanation:

The ATP-binding cassette (ABC) transporters are a type of carrier protein involved in active transport. These transporters use ATP to move molecules across the membrane. So, ATP-binding cassette transporter A, ATP-binding cassette transporter B, and ATP-binding cassette transporter C are all ABC transporters. On the other hand, Non-ATP-binding cassette transporter X is not an ABC transporter.
