What is another term often used to refer to active-transport transporters?

Receptors

Pumps (correct)

Carriers

Channels

Which type of transporters exhibit specificity and saturation similar to facilitated-diffusion transporters?

Secondary active transporters (correct)

Antiport system transporters

Symport system transporters

Primary active transporters

In active transport, the flux via the transporter is maximal when:

The transporter is non-specific

The transporter binding sites are empty

The transporter is saturated with inhibitors
