which two terms describe the transport protein illustrated in the image?
□ symporter
□ uniporter
□ abc transporter
□ antiporter

Explanation:

1. Uniporter: A uniporter transports a single type of solute across the membrane. The image shows one solute (the green hexagon) being transported, so uniporter applies.
2. ABC transporter: ABC transporters use ATP (seen here with the ATP - binding domain) to transport solutes. The presence of the ATP - binding domain and the solute - binding protein fits the ABC transporter structure.
3. Symporter/Antiporter: Symporters transport two solutes in the same direction, antiporters in opposite directions. The image shows only one solute, so these don't apply.

Answer:

B. Uniporter, C. ABC transporter
