| The proximal tubule is the site of most secretion, reabsorption, and active transport. |
|
| The electrocytes establish a charge difference across the cell membranes, presumably by active transport of ions. |
|
| Uric acid, formed from nucleic acids, is reabsorbed from filtrate by active transport, and a small portion is actively secreted into the urine. |
|
| Complex processes regulate both passive and active transport across the nuclear membrane. |
|
| The human placenta, characterized by the processes of passive transport and facilitated diffusion, contains numerous active transport proteins. |
|
| Another role of insulin is to stimulate the active transport of amino acids into cells. |
|
| The next step in this process is malnutrition, since active transport of nutrients become impaired. |
|
| A pH gradient across the ruffled membrane is the consequence of active transport mechanisms by the osteoclasts. |
|
| The four types of chemical transport systems through cell membranes are diffusion, facilitated diffusion, active transport, and pinocytosis. |
|
| The active transport pathway is mediated by transporters and is divided into influx and efflux. |
|
| The pharmacokinetics of metformin are largely determined by its active transport by key organic cation transporters. |
|
| This website includes the 2003 National Roundtable Proceedings along with information on active transport, including a list of events. |
|
| He emphasizes the fact that public and active transport are accessible, and that using them contributes to improving our quality of life. |
|
| Amino acids and di-peptides cross the cell membrane by active transport and facilitated diffusion, which are mechanisms that require metabolic energy. |
|
| The enzyme isoforms seem to have a tissue-specific expression, showing the highest expression levels in cells where intense active transport is expected to occur. |
|
| A study using probenecid demonstrated that the nonlinearity in blood levels is in fact due to a saturation of the active transport pathway in the kidney. |
|
| Within the vacuole is the cell sap, a water solution of salts and sugars kept at high concentration by the active transport of ions through permeases in the vacuole membrane. |
|
| This is an expected outcome of inhibiting the active transport system in the kidneys and is not necessarily indicative of the system becoming saturated. |
|
| This means that strontium, like calcium, is at least partially absorbed by active transport. |
|
| This enzyme is responsible for the active transport of sodium and potassium ions through the cellular membrane. |
|
|
|
| With our online transport directory TC Profile® you have direct access to 30.000 active transport and logistics service providers throughout Europe. |
|
| The number of cargo transfers during the shipment of Category II nuclear material, and the length of time the shipment is in active transport, should be minimized. |
|
| Neutral amino acids have certain structural requirements for active transport, and if these specific structural arrangements are disturbed, active transport will not occur. |
|
| It is this coupling that creates primary active transport. |
|
| Urban planning can promote healthy behaviour and safety through: investing in active transport, designing areas to promote physical activity and passing regulatory controls on tobacco and food safety. |
|
| Gay is prioritising cars over active transport – bikes and walking. |
|
| Shortcutting concerns in the community are very limited and residents find it safe and comfortable to walk, cycle or get around Sunny Brae by other means of active transport. |
