Active transport counters the process of diffusion?
Yes, active transport is a process in which cells use energy to move molecules against their concentration gradient, whereas diffusion is a passive process where molecules move from an area of high concentration to an area of low concentration. Active transport allows cells to transport molecules against their concentration gradient, which is opposite to the direction of diffusion.
Does phagocytosis go against concentration gradient?
Yes, phagocytosis does go against the concentration gradient. This process involves the engulfing of large particles or pathogens by immune cells, such as macrophages, which requires energy in the form of ATP. Unlike passive transport mechanisms that move substances along their concentration gradient, phagocytosis actively transports materials into the cell, making it an active process.
What is concerntration gradient?
As used in the process of diffusion, the concentration gradient is the graduated difference in concentration of a solute within a solution (as expressed per a unit distance). Molecules tend to move from areas of greater concentration to areas of lesser concentration. i.e. down the gradient.
Which term describes the difference in the substance across a cells membrane?
Concentration Gradient.. :)
Why is there a diffusion gradient in the tissues?
A diffusion gradient exists in tissues due to differences in concentration of substances. This gradient drives the passive movement of molecules from areas of higher concentration to areas of lower concentration, allowing cells to obtain necessary nutrients and get rid of waste products.
What is required when cells must move materials against a concentration gradient?
Active transport which requires ATP.
What kind of concentration forms whenever there is a difference in concentration between one place and another?
A gradient forms when there is a difference in concentration between two places. This gradient drives the movement of substances from areas of higher concentration to areas of lower concentration through processes such as diffusion or osmosis.
Active transport counters the process of diffusion?

What is a characteristic that diffusion and active transport have in common and both process?
Both involve the transport of materials across the cell membrane. Active transport goes against the concentration gradient and requires ATP. Diffusion goes with the concentration gradient, or from high to low concentration, and does not require ATP. ATP is the standard unit of energy in cells.

What is H plus concentration gradient?
The H+ concentration gradient refers to the difference in concentration of hydrogen ions (H+) across a membrane or barrier. This gradient can be used by cells to drive various processes such as ATP synthesis in mitochondria or neurotransmitter release in neurons. The movement of H+ ions down their concentration gradient can generate energy in the form of a proton motive force.
Why is there a diffusion gradient in the tissues?
A diffusion gradient exists in tissues due to differences in concentration of substances. This gradient drives the passive movement of molecules from areas of higher concentration to areas of lower concentration, allowing cells to obtain necessary nutrients and get rid of waste products.
How does a cell maintain differences in concentration of certain ions on either side of the plasma membrane?
Cells maintain unequal concentrations of ions on opposite sides of a cell membrane through active transport.
Most water enters and leaves cells by?
Water moves between cells by osmosis, down a concentration gradient.
