Transport systems have been classified into three major categories: 1) diffusion, 2) facilitated, and 3) active transport. Generalized models of transport systems have been proposed. These models have a specific membrane component which serves as a carrier to a substrate. Passive diffusion uses a carrier that transports in or out depending on the concentration on both sides of the membrane. Active transport utilizes a charged substrate or carrier to transport unidirectional against a gradient using metabolic energy. It is apparent that membrane transport is a complex, complicated phenomenon. This paper is a study of galactose transport in Acetobacter aceti var. liquefaciens a strict aerobe, to determine is characteristic mechanism(s).
