A concentration gradiant is a common term used in Biology to signify that one side of a membrane contains a significantly higher amount of ions/atoms/molecules than the other side. This esentially means that in a concentration gradient you have stored energy. This is a common term used when talking about the formation of ATP.
What else can I help you with?
Is osmosis form of active transport or passive transport?
It is a type of passive diffusion, as the water travels along a concentration gradiant. As opposed to active transport, where the substances can pass against a concentration gradiant.
What is osmosis in detail?
Osmosis is the movement of water across a partially permeable membrane down the concentration gradiant from an area of high concentration to an area of low concentration until an equilibrium is achieved.
Is osmosis trans active?
Osmosis is a passive form of diffusion as it travels downa concentration gradiant, as opposed to active transport; a type of diffusion that can go against a conc. grad.

How do you work out the gradiant on a ramp?
Divide the height of the ramp by the length of the ramp (rise over run).
What is pseudohearts?
Pseudohearts are structures that resemble the shape of a heart, but do not have the same function or characteristics as a biological heart. They are often used in the context of art, design, or symbolic representations.
Why is the anatomical arrangement of the loop of henle so important?
The anatomical arrangement of the loop of Henle is crucial for creating a concentration gradient in the kidney that allows for reabsorption of water and solutes. This concentration gradient is essential for the kidney to regulate water balance and concentrate urine.
Why do rivers speed up even when the radiant decreases?
There is less friction from the bed and banks of the river downstream (where the gradiant decreases) so the velocity increases.
Contrast active and passive transpot.?
PASSIVE TRANSPORT: when there is a transport of solutes from there higher concentration to their lower concentration across the semipermeable membrane as plasma membrane without any utilization of energy is called passive transport. ACTIVE TRANSPORT: When there is a net flow of solutes from there low concentration to their high concentrain of flow against the concentration gradiant with the utilization of energy is called active transport. e.g. Na+- K+ exchange pump.
Is osmosis an active transport?
It is a type of passive diffusion, as the water travels along a concentration gradiant. As opposed to active transport, where the substances can pass against a concentration gradiant.
What is the difference in the concentration of a substance across a space is called concentration?
The difference in concentration of a substance across a space is called a concentration gradient. It represents the change in concentration over a given distance and drives processes like diffusion and osmosis. Substances move from areas of high concentration to areas of low concentration along the concentration gradient to achieve equilibrium.
What concentration gradient moves when a low concentration moves from an area of a higher concentration?
The low concentration moves down its concentration gradient from an area of high concentration to an area of low concentration. This process is driven by diffusion, where particles move spontaneously from regions of high concentration to regions of low concentration until equilibrium is reached.
