It is a solute that causes osmosis to occur. For instance, if a solution contains sucrose and the membrane is impermeable to sucrose,, water will move out of the cell and into the solution to dilute it. Hence the solution is hypertonic. Sucrose would be considered an osmotically active solution in this case because it induces osmosis of water across a membrane.
What else can I help you with?
What processes could result in the net movement of a substance into a cell if the substance is more concentrated in the cell than in the surroundings?
Active transport or facilitated diffusion could result in the net movement of a substance into a cell if it is more concentrated inside the cell than in the surroundings. In active transport, energy is required to move the substance against its concentration gradient. In facilitated diffusion, specific carrier proteins help the substance move into the cell down its concentration gradient.
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
Term for the movement of substance against a concentration gradient?
active transport eduction. this is the process in which this moves across. peanut butter jelly time
When a substance moves from an area of low concentration to an area of high concentration while using energy the proces is termed what?
active transport
Movement of a substance across a cell membrane using chemical energy occurs during?
Active transport is the movement of a substance across a cell membrane using chemical energy. This process requires the use of a carrier protein and ATP to transport molecules against their concentration gradient.
If a substance is unable to diffuse across a membrane we say the membrane is?
osmotically active
What component of the molasses solution was osmotically active?
Sugar is the component of a molasses solution which is osmotically active.
Are osmotically active substances simple diffusion or active transport?
simple diffusion.
Is urea osmotically active?
Yes, urea is considered to be osmotically active. It can contribute to the osmotic pressure of a solution by attracting water molecules and affecting the overall concentration of solutes.
Is lactic acid osmotically active?
Yes, lactic acid is considered osmotically active because it can contribute to changes in the osmotic pressure of a solution. When present in a high concentration, lactic acid can affect the movement of water across cell membranes.
Why does glucose and Sodium chloride behave osmotic ally different?
Glucose and sodium chloride behave differently osmotically because each formula unit of glucose behaves as a single osmotically active unit, but each formula unit of sodium chloride behaves as two osmotically active units: Each formula unit dissociates in solution into two ions, and the two ions act as osmotically independent units.
What happens when water is osmotically removed from a plant?
When water is osmotically removed from a plant bad things could happen. When the plant is dehydrated i could die.
What are active pharmaceutical ingredients?
Every drug has two components, one is the main substance which is the active pharmaceutical ingredient and the other is the inert substance, which can be the solvent in which the active ingredient is suspended.
Explain active transport?
Active transport is the movement of a substance against its concentration energy.
How is competitive inhibition different from competitive inhibition?
Competitive Inhibition is a substance that binds to the active site in place of the substance while Non-competitive Inhibition is a substance that binds to a location remote from the active site. (:
How can you identify is the substance is optically active?
A substance is optically active if it has the ability to rotate plane-polarized light. This can be detected using a polarimeter, which measures the extent and direction of rotation caused by the substance. Optically active substances have chiral centers that do not have a plane of symmetry, making them capable of rotating the plane of polarized light.
What processes could result in the net movement of a substance into a cell if the substance is more concentrated in the cell than in the surroundings?
Active transport or facilitated diffusion could result in the net movement of a substance into a cell if it is more concentrated inside the cell than in the surroundings. In active transport, energy is required to move the substance against its concentration gradient. In facilitated diffusion, specific carrier proteins help the substance move into the cell down its concentration gradient.
