- The pump for sodium and potassium is called sodium-potassium pump or Na +/K+-ATPase. In the epithelial cells of the stomach, gastric acid is produced by hydrogen potassium ATPase, an electroneutral pump. Water, ethanol, and chloroform exemplify simple molecules that do NOT require active transport to cross a membrane.

- Answered by The Community. Making the world better, one answer at a time. NADH produces 3 ATPs because it donates the proton at a higher location in the electron transport chain than does FADH2, which is why FADH2 produce only 2 ATPs. NADH and FADH2 donates electrons and protons into the electron transport chain.

Shared Flashcard Set A single ATP-powered pump that transports a specific solute can indirectly drive the active transport of several other solutes. Ex: a plant cells proton pump creates a gradient of H+ ions which then go back across the membrane and drive the active transport of amino acids, sugars, etc.

- As with the mitochondrion, a bacterial ATPase lets protons (under the protonmotive force) into the cytoplasm, using them to make ATP. So, though they don't have mitochondria, bacteria can generate energy through glycolysis and by generating a proton gradient across their cell membranes! Unlike mitochondria, some bacteria can use light to generate a proton gradient, and therefore ATP. You can find out more about these topics by reading a good college-level biochemistry textbook, like Biochemistry by L. Stryer.

Structural Biochemistry/Membrane Proteins/Active Transport The cycle repeats. In this sodium/potassium pump, sodium is transferred out of the plasma membrane and potassium is pumped inside the plasma membrane. Since active transport requires energy, it uses ATP or it couples to molecules moving down the concentration gradient.

Active transport: the sodium-potassium pump When an enzyme in the pump, called sodium-potassium-ATPase, splits the phosphate from the ADP, the energy released powers the transport action of the pump. Passive transport: membrane channels. The sodium-potassium pump sets the membrane potential of the neuron by keeping the concentrations of Na + and K + at constant

How does the sodium-potassium pump work? The sodium-potassium pump uses active transport to move molecules from a high concentration to a low concentration. The sodium-potassium pump moves sodium ions out of and potassium ions into the cell. This pump is powered by ATP. For each ATP that is broken down, 3 sodium ions move out and 2 potassium ions move in. In more detail: Sodium ions bind to the pump and a phosphate group from ATP attaches to the pump, causing it to change its shape. In this new shape, the pump releases the three sodium ions and now binds two potassium ions. Once the potassium ions are bound to the pump, the phosphate group detaches.

- Electron Transport System - Biology Video by Brightstorm. So as CN- binds, cytochrome c oxidase cannot use oxygen as the final electron acceptor. The electron transport chain (ETC) cannot continue to establish a proton gradient across the inner mitochondrial membrane so ATPase stops functioning and producing ATP. That means the major chunk of ATP supposed to be produced in aerobic respiration is lost.

Which method of cellular transport does require energy? which method does not? Active transport requires the use of energy or ATP. In active transport you go against the concentration gradient, and for that ATP is used. Their are two types of active transport. Primary and secondary active transports and both use ATP, thou secondary uses less ATP than primary. Passive transport does not use any ATP.

- The proton pump is a type of active transport. The pump requires energy to transport the protons that it receives, not from ATP, but rather from electrons transferred from NADH. It pumps protons across the membrane against their concentration gradient.

ATP Synthase ATP synthase is a complex which makes use of the proton potential created by the action of the electron transport chain in mitochondria.It transports a proton down the gradient and uses the energy to complete the phosphorylation of ADP to ATP.o part of its action is like a molecular motor. In the electron transport chain of photosynthesis, the ATP synthase complex accomplishes the phosphorylation of ADP to ATP, providing part of the energy for subsequent biosynthesis through the Calvin cycle.

- The flow of protons which creates the ATP is chemiosmosis. The ATP can then be used in the light independent stage of photosynthesis or to actively transport potassium ions into the guard cells, so they become turgid as a result of water entering by osmosis.

- The hydrogen ion gradient created by the electron transport chain is utilized by ATP synthase to create ATP from ADP and Pi. This is similar to the way ATP is synthesized in the mitochondria. ATP, NADPH, and molecular oxygen are the final, vital, products of photosynthesis.

How does the Sodium/Potassium Pump maintain the cell's Resting Membrane Potential? Also note that the pump continues to move Na+ out of the cell even when more Na+ ions are present there. In other words, Na+ is being pumped (and K+ in) against their concentration gradients. Because this pump is moving ions against their concentration gradients it requires energy in the form of ATP.

Mitochondria 1 The energy stored in the proton gradient is also used for the active transport of several molecules and ions through the inner mitochondrial membrane into the matrix. 2  NADH is also used as reducing agent for many cellular reactions. The gradient of protons formed across the inner membrane by this process of active transport forms a miniature battery. 2  The protons can flow back down this gradient only by reentering the matrix through ATP synthase, another complex (complex V) of 16 integral membrane proteins in the inner membrane.

Chemiosmosis In most cases the proton motive force is generated by an electron transport chain which acts as a proton pump, using the energy of electrons from an electron carrier (Gibbs free energy of redox reactions) to pump protons (hydrogen ions) out across the membrane, separating the charge across the membrane.hemiosmosis is the movement of ions across a selectively permeable membrane, down their electrochemical gradient.
