What else can I help you with?
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
During active transport substances move from regions of what?
in active transport, where do molecules always go
Molecules move from an area of low concentration to an area of high concentration during?
Active transport. This process requires energy to move molecules against their concentration gradient, typically through the use of transport proteins in the cell membrane.
What are two differences between active transport and passive transport in terms of energy?
Active transport requires energy in the form of ATP to move molecules across the cell membrane against their concentration gradient, while passive transport does not require energy and relies on the concentration gradient to move molecules from an area of higher concentration to an area of lower concentration. Additionally, active transport can move molecules in both directions across the membrane, while passive transport can only move molecules down the concentration gradient.
What type of transport requires energy to move molecules from an area with low concentration to an area of high concentration?
Active transport is needed to move molecules from an area of low concentration to an area of higher concentration against their concentration gradient. ATP is used as the power source.
Is active transport able to move molecules against the concentration gradient?
Yes, active transport is able to move molecules against the concentration gradient.
Does active transport move molecules against the concentration gradient?
Yes, active transport moves molecules against the concentration gradient.

How does facilitated transport differ from active transport in terms of the energy requirements and mechanisms involved in moving molecules across a cell membrane?
Facilitated transport and active transport are two ways molecules can move across a cell membrane. Facilitated transport does not require energy from the cell, while active transport does require energy in the form of ATP. Facilitated transport uses carrier proteins to help molecules move across the membrane, while active transport uses pumps to move molecules against their concentration gradient.
Does active transport result in an even distribution of molecules?
No. Active transport uses energy to transport specific molecules against a concentration gradient. Passive transport will result in an even distribution of molecules because they allow molecules to move down a concentration gradient.
Molecules move from an area of low concentration to an area of high concentration during?
Active transport. This process requires energy to move molecules against their concentration gradient, typically through the use of transport proteins in the cell membrane.
In what ways do molecules move?
it moves by diffusion, osmosis and active transport
Is facilitated diffusion an example of active transport?
No, facilitated diffusion is a type of passive transport where molecules move across a cell membrane with the help of transport proteins. Active transport, on the other hand, requires energy to move molecules against their concentration gradient.
How is active transport diffrent from osmosis?
Active transport occurs when molecules are moved from an area of low concentration to an area of high concentration. The cell membrane acts as a semi-permeable barrier during the process. Energy is required for active transport. Osmosis is a type of passive transport. Passive transport is similar to active transport except it requires no energy and molecules move from an area of high concentration to an area of low concentration. Osmosis occurs only if the molecules moving across the cell membrane are WATER molecules.

Active transport requires energy in the form of ATP to move molecules across the cell membrane against their concentration gradient, while passive transport does not require energy and relies on the concentration gradient to move molecules from an area of higher concentration to an area of lower concentration. Additionally, active transport can move molecules in both directions across the membrane, while passive transport can only move molecules down the concentration gradient.
