Down concentration gradient meaning
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, … WebThe concentration gradient of the glomerular filtrate is also important for the juxtamedullary nephrons, as it allows for the secretion of metabolic waste products and toxins into the tubular fluid. This process is known as tubular secretion and can be an active or passive process, depending on the type of waste product.
