If the substance entering the cell was in higher concentration inside the cell then outside the cell what type of transport would be required?
It would be active transport, a process which requires a cell to use its own energy (unlike passive transport).
What else can I help you with?
Why transport proteins require energy to function in active transport?
Because there is a higher concentration inside the cell then out side ....because it requires energy to move the molecules outside in a different direction then they would normally move, it is like riding a bike up a hill it requires energy.
Which of the following required the most ATP to move the molecule across a plasma membrane?
Ion moving against a concentration gradient
What is diffusion and facilitated diffusion?
Facilitated diffusion is a process whereby a substance passes through a membrane with a aid of an intermediary or a facilitator. The facilitator is an integral membrane protein that spans the width of the membrane. The force that drives the molecule from one side of the membrane to the other is the force of diffusion. and Diffusion is the process of movement of a substance from the region of higher concentration to the region of lower concentration so as to spread uniformly. Difference : Facilitated diffusion is when polar or charged molecules cross the cell membrane through a trans membrane channel protein. Diffusion is when small, non-polar molecules cross the cell membrane directly through the lipid bilayer. they can do so as they are hydrophobic and hence can pass through the hydrophobic core of the lipid bilayer. crossing the lipid bilayer is difficult for charged/polar particles as they are hydrophilic and large (as they may have hydration shells due to their charged nature), hence they have to cross through transport proteins.

What energy is required for passive transport?
By definition, passive transport on a cellular level requires no energy other than some sort of gradient, whether of the molecule in question, or another whose movement across the membrane can be linked to the one of interest.
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.
What must happen when a concentration gradient is eliminated?
When a concentration gradient is eliminated, there will be no difference in the concentration of a substance across a region. This can lead to equilibrium, where molecules are evenly distributed, or in the case of active transport, energy may be required to maintain the concentration gradient.
Why is energy required in passive transport to occur?
Energy is not required for passive transport to occur. Passive transport processes such as diffusion and osmosis rely on the inherent kinetic energy of molecules to move from an area of high concentration to an area of low concentration without the need for external energy input.
How can the concentration of a substance be determined alkalimetrically?
The concentration of a substance can be determined alkalimetrically by titrating it with a known concentration of a base (alkali) until the equivalence point is reached. The volume of the base required to reach the equivalence point is used to calculate the concentration of the substance.
Do passive and active transport requires energy?
Passive transport does not require energy as it relies on the movement of molecules from an area of high concentration to low concentration, driven by the concentration gradient. Active transport, on the other hand, requires energy in the form of adenosine triphosphate (ATP) to move molecules against their concentration gradient, from low concentration to high concentration.
Does Passive transport uses ATP to move molecules against their concentration gradient?
No, passive transport does not require ATP because it moves molecules along their concentration gradient, from an area of higher concentration to an area of lower concentration. ATP is only required for active transport, which moves molecules against their concentration gradient.
Is a cell required for passive transport?
No. Diffusion (passive transport) can take place without a cell. For example, if you were to put some coloured food dye into a cup of water, the food dye would spread until it eventually was a uniform colour. This is the process of diffusion, which is the movement of a substance down a concentration gradient. Passive Transport means no energy is required.
What are all the differences between active and passive transport?
Passive transport occurs when the concentration of something on one side of membrane is different from the concentration on the other side. It occurs when that substance can pass through the membrane, and always in the direction of more -> less. No energy is required to make the substance move; in fact, this movement generates energy. This is like rolling a rock down a hill--it just does it on its own.Active transport occurs in the opposite direction, from less -> more. It requires energy for transport. This is like rolling a rock up a hill--you have to push it the entire way!Both involve the transport of a substance across a membrane, and the change in concentrations on different sides of a membrane. Both are also important to the proper functioning of a cell.Active transport requires energy, but passive transport requires none.Active transport requires a special protein to make the transport occur, but passive transport requires none.
How is the active transport different from diffusion?
The main difference is that diffusion does not require energy and active transport does require energy. Just for the record diffusion has a concentration that moves from high to low, and active transport has a concentration that moves from low to high. (Hope this helps to answer your question!)
What best describes passive transport?
it moves materials from areas of high concentration to areas of low concentrationit moves materials of high concentration to areas of low concentration
Materials can be moved from a low concentration to a high concentration through?
active transport processes like primary active transport or secondary active transport, which require energy to move molecules against their concentration gradient. This can involve the use of transport proteins or ion pumps in the cell membrane.
How can a titration help you to determine the concentration of an unknown substance?
In a titration, a known concentration of a substance (titrant) is added to the unknown substance until a chemical reaction reaches completion. By measuring the volume of titrant required to reach a specific endpoint, the concentration of the unknown substance can be calculated using the stoichiometry of the reaction.
