In the mitochondria phosphate ion (PO4³-)and H+ are transported together from the intermembrane space into the matrix.Which statement applies?
A)The transport protein is a symport.
B)The transport protein must have a relatively large central channel to accommodate both ions.
C)The interior of the transport protein must be uncharged.
D)All of the above.

A symport is a type of transport protein that moves two or more ions or molecules in the same direction across a membrane. In this case, phosphate ion and H+ are transported together from the intermembrane space into the matrix of mitochondria, which means that the transport protein is a symport. Choices B and C are not necessarily true and not applicable to this scenario.
