  • Nigericin and Valinomycin's Effect On Electron Transport Chain

    In other words, instead of passing through the ATP synthetase enzymes and thereby using the release of free energy to produce ATP, the H+ can pass through the membrane directly being shuttled by nigericin.

  • How do substances (ions, proteins, ligands etc. etc.) cross

    This energy can come from establishing a gradient or using molecules (such as ATP) to transfer energy. A gradient can be established through concentration or by electrical potential.

  • Electron Transport Chain.

    As the electrons move from one carrier to the next in the electron transport system, free energy is liberated. This free energy is used to move protons across the inner mitochondrial membrane.

  • Active and Passive Transport in Plant Cells

    The charge separation is a form of potential (stored) energy used to perform cellular work. Plant cells use the stored energy in the proton gradient and the membrane potential to drive the transport of numerous different solutes.

  • type of transport mechanism

    The free energy for the transport process is provided by other means, i.e. hydrolysis of high energy phosphate group, concentration gradient of a secondary ion, etc.

  • Discussin of Membrane Transport

    In other words, as the ions move down their concentration, they give off enough free energy to drive the movement of an active transport process.

  • Discussion of Diffusion, Osmosis and Cell Membrane Potential

    This creates an electrical potential across the cell membrane which is important for the function of the cell. Think of a neuron (brain cell). Have you heard that neurons communicate using electrical signals to relay information?

  • Discussion of various cellular respiration questions

    If the inner mitochondrial membrane allowed protons to move freely back and forth across it, there would be no ATP synthesis in electron transport. Explain why. The inner membrane acts as a barrier to the free diffusion of H+ ions.

  • Analysis of electron transport system

    ii. for one electron pair, the amount of potential energy in the proton gradient which is theoretically available for ATP synthesis under standard conditions.
