In secondary active transport, one ion is allowed to move down its electrochemical gradient. This results in increased entropy that can be used as a source of energy. For example, Na+ ions moving down the electrochemical gradient across the plasma membrane power up the transport of a second ...
Active transportmechanisms require the use of the cell’s energy, usually in the form of adenosine triphosphate (ATP). If a substance must move into the cell against its concentration gradient—that is, if the concentration of the substance inside the cell is greater than its concentration in t...
Describe the ABC transport system. What does ABC stand for and how does the system work? Explain briefly how an amoeba moves and describe its structure. What is osmosis? Use an example of this function. Explain how biological rhythms influence your daily functioning and describe how biology and...

Give an example of each type. What are diffusion and facilitated diffusion? What type of transport is it? Facilitated diffusion utilizes what to move material across the cell membrane? What is a cell membrane in conjunction with biology? Which statement best describes how active transport differs ...

In E. coli vesicles, most of these transport systems are coupled to an electrochemical gradient of protons (deltamuH+, interior negative and alkaline) generated primarily by the oxidation of D-lactate or reduced phenazine methosulfate via a membrane-bound respiratory chain. Oxygen or, under ...
A previous study (Bull. Math. Biophysics,30, 735–749) is generalized to the case of active transport, which acts together in general with ordinary di
41) promotes enhancement of active transport nonlinearly, potentially enabling patchy-to-homogenized resource distribution (for example, molecular concentrations) at the onset of the extrusion events. Further afar, confluent colonies can harness active flows for shuttling sub-micrometre- to micrometre-sized...
