What does active transport look like?
The only different between passive and active transport is the use of energy. In passive transport, molecules can either diffuse across the membrane, go through an aquaporin or use a passive transporter. In active transport, energy needs to be released, and it is usually because you are trying to transport a molecule or ion up its concentration gradient.
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.
Does active transport requires energy?
Yes, active transport requires energy because it moves molecules or ions against their concentration gradient, from an area of low concentration to an area of high concentration. This process requires the cell to expend energy in the form of ATP to drive the transport proteins involved in active transport.
How do most molecules cross the cell membrane?
Most molecules cross the cell membrane through passive diffusion, facilitated diffusion, or active transport. Passive diffusion relies on the concentration gradient, facilitated diffusion involves the use of protein channels or carriers, and active transport requires energy to move molecules against their concentration gradient.
What is the active transport and passive transport?
The requirements of passive transport through the cell membrane (phospholipid bilayer) of an animal cell are that the molecule is non-polar or small enough to pass by the non-polar phospholipid tails. This is because, for there to be passive transport, no energy must be used to transport the molecule from outside of the cell to inside.
What is the difference between active and passive cellular transport?
Active transport requires energy; passive transport does not.
Osmosis is what type of transport?
Osmosis is a passive transport process where water molecules move across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration. It does not require energy input from the cell.
How are active transport and passive transport different from each other?
Active transport requires energy input to move substances across a membrane against their concentration gradient, while passive transport does not require energy as it moves substances along their concentration gradient. Active transport is selective and requires specific transport proteins, while passive transport occurs through simple diffusion or facilitated diffusion.
What is the function of passive transport?
Passive transport is a biological process that allows molecules to move across a cell membrane without the use of energy. It occurs down the concentration gradient, from an area of high concentration to an area of low concentration. Common types of passive transport include simple diffusion, facilitated diffusion, and osmosis.
Seven word that has to do with transport that does not require energy?
I'm going to go with osmosis, which is the passive transport of water across a membrane from higher to lower concentration.

How are active and passive differ from from each other?
The most basic difference between active and passive transport is that active requires energy while passive does not. You would require active transport if the substance is going against the concentration of molecules inside and outside of the membrane or if the substance is particularly large. Passive is more for smaller molecules that go with the concentration of the molecules inside and outside of the membrane.
Why is energy needed for transport?
Molecules are moving against a 'concentration' gradient. Active transportation moving from low to high concentration, while passive transportation such as osmosis and diffusion go from high to low concentration.
Why do you call diffusion and osmosis passive transport?
Simply, it is the opposite of active transport. It does not "spend" chemical energy. Since passive transport is diffusion, molecules will move from higher areas of concentrations to lowers areas of concentrations and no outside force is needed (unlike active transport).
Why does active transport energy?
Active transport requires energy because you are going against a gradient. Active transportation moving from low to high concentration, while passive transportation such as osmosis and diffusion go from high to low concentration. One example of passive transportation is a river. Floating downstream does not require any energy. You are simply moving with the gradient. If you wanted to go upstream, you would have to paddle. This requires an input of energy similar to active transport.
Does active transport requires energy?
Yes, active transport requires energy because it moves molecules or ions against their concentration gradient, from an area of low concentration to an area of high concentration. This process requires the cell to expend energy in the form of ATP to drive the transport proteins involved in active transport.
