Lactose Transporter How Does it Work

The video explains the lactose transporter, a type of secondary active transport, which requires a proton pump to function. The pump creates a proton concentration gradient, enabling lactose to be transported into the cell. The mechanism involves protonation of a carboxyl group, leading to a conformational change in the transporter protein. Inhibition of the proton pump disrupts this process. The video concludes with a preview of primary active transport.
