Gradient definition in biology
WebWord & Picture Definition Protein pump Found in the cell membrane and is responsible for pushing molecules up their concentration gradient into or out of a cell. This requires ATP and is commonly used to move protons, sodium and potassium. This describes the cell membranes ability to let some items pass directly though while preventing others. Small, … WebGradient definition: A vector having coordinate components that are the partial derivatives of a function with respect to its variables.

WebEnergy released in these reactions is captured as a proton gradient, which is then used to make ATP in a process called chemiosmosis. Together, the electron transport chain and chemiosmosis make up oxidative phosphorylation. The key steps of this process, shown in simplified form in the diagram above, include: Web1. Description of Diffusion and Osmosis. A water solution that contains nutrients, wastes, gases, salts and other substances surrounds cells. This is the external environment of a cell. The cell’s outer surface of the plasma membrane is in contact with this external environment, while the inner surface is in contact with the cytoplasm.

WebDiffusion is the net movement of a substance from high concentration to low concentration. This difference in concentration is referred to as a concentration gradient. This movement does not require any external energy, but uses the free energy intrinsic to the system. Temperature Effects on Diffusion. Temperature/Diffusion Simulation.
