Explain the concept of devolution in biology. 1. Describe the movement of ions for each region of the nephron. 2. Which ions are leaving the tubule, and is the transport active or passive? Answer of the following question. What is active transport and what is its responsibility in the body...
Active:An Active transport in biology refers to the process by which molecules or ions are actively transported across a cell membrane against their concentration gradient, from an area of lower concentration to an area of higher concentration. Passive:An Passive transport, also known as passive dif...
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...
Active transport is a type of cellular transport in which substances (e.g. ions, glucose, and amino acids) are transported across a biological membrane towards the region that already contains a lot of such substances. Because of this, active transport uses chemical energy (e.g. ATP) to mov...
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 ...
SEVERAL mechanisms have been proposed which link the active transport of Na + and K + to the hydrolysis of ATP. These suggest either diffusion across the membrane of specific carriers of Na + and K +1–3 , or the formation of a phosphorylated membrane derivative 4–7 . Evidence in favour...
Contributions of secondary active transport processes to membrane potentials Equations are developed to examine the effects of secondary active transport processes on the steady-state membrane potential of symmetrical cells. It is s... LGM Gordon,ADC Macknight - 《Journal of Membrane Biology》 被引量...
