Molecules move up a concentration gradient through a process called passive transport. This involves the movement of molecules from an area of low concentration to an area of high concentration, driven by the natural tendency of molecules to spread out and reach equilibrium. This movement can occur through processes such as diffusion or osmosis, where molecules move across a membrane without the need for energy input.

How does the process of active transport move molecules up the concentration gradient?
Active transport moves molecules up the concentration gradient by using energy from ATP to pump molecules against the natural flow, from an area of low concentration to an area of high concentration. This process requires specific transport proteins in the cell membrane to actively move the molecules.
How do molecules travel in passive transport when moving up their concentration gradient?
In passive transport, molecules move up their concentration gradient without using energy. This process relies on the natural movement of molecules from areas of high concentration to areas of low concentration. This movement is driven by the principle of diffusion, where molecules spread out to achieve a balance.
Does passive transport move up or down the concentration gradient?
Passive transport moves down the concentration gradient, from an area of higher concentration to an area of lower concentration.
What types of transport moves molecules along a concentration gradient?
I'm not sure you're understanding the question you are asking. Molecules are the tiny building blocks, made up of atoms, that are used to create everything in our galaxy. Cells are a single living unit that work together to be a living thing. If you are interested in how parts of a cell move around or pass along material, you should look up how cells work or ask a more specific question.
Which method of material exchange uses up energy?
Active transport uses energy to move molecules against their concentration gradient across a cell membrane. Energy is required to pump molecules such as ions or nutrients from an area of low concentration to an area of high concentration. This process is driven by cellular energy sources such as ATP.

Does passive transport move up or down the concentration gradient?
Passive transport moves down the concentration gradient, from an area of higher concentration to an area of lower concentration.
Does active transport move from higher to lower concentration?
Active Transport- When molecules move from an area of lower concentration to an area of higher concentrationPassive Transport- When molecules move from an area of higher concentration ot an area of higher concentration (also called diffusion)
Which type of transport uses energy passive or active transport?
Active transport uses energy to move molecules across a cell membrane against their concentration gradient, typically via protein pumps. Passive transport, on the other hand, does not require energy and relies on the natural flow of molecules from high to low concentration.
Why was concentration gradient set up?
the concentration gradient was set-up because they wanted to kill the Jews

Is active or passive transport involved?
In active transport the ATP is used to pump molecules up the concentration gradient. Transport of molecules occurs from a low concentration of solute to high concentration of solute and requires cellular energy. While passive transport involves carriers, channels, or direct diffusion through a membrane.
Which method of material exchange uses up energy?
Active transport uses energy to move molecules against their concentration gradient across a cell membrane. Energy is required to pump molecules such as ions or nutrients from an area of low concentration to an area of high concentration. This process is driven by cellular energy sources such as ATP.
How does humidity affect osmosis?
Humidity can affect osmosis by influencing the rate at which water molecules move across a semi-permeable membrane. Higher humidity levels can slow down the rate of osmosis by reducing the concentration gradient between the solutions on either side of the membrane. Conversely, lower humidity levels can speed up osmosis by creating a greater concentration gradient.
What is active transport and passive transport?
active transport requires the use of energy aka ATP and is usually against the concentration gradient. passive transport does not require energy because it moves in response to the concentration gradient.
Why is diffusion also called active transport?
Diffusion and active transport are not the same thing. Diffusion is when molecules pass from an area of high concentration to an area of low concentration. They travel down a concentration gradient. They do this naturally, like if perfume is sprayed at one end of the room, it spreads to the other end, because there is a low concentration of spray at the other end, see? Active transport is when a cell actively moves molecules from one side of its membrane to the other. It is often travelling up a concentration gradient, so it is going from an area of low concentration to an area of high concentration- the opposite of diffusion.
