What three things can affect the rate of diffusion?
Diffusion refers to the process where substances from a highly concentrated area move to a place with a lower concentration. The three factors that affect the rate of diffusion are temperature, concentration gradient and the molecular weight of the substances.
Diffusion is important in body fluids because it tends to?
equalize concentration gradients, allowing for the movement of molecules from areas of high concentration to low concentration. This process is crucial for maintaining proper balance of nutrients and waste products in body fluids, ensuring proper cell function.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What process moves materials through a cell from areas of low concentrate to areas of high concentration?
Active transport is the process that moves materials through a cell from areas of low concentration to areas of high concentration by utilizing energy in the form of ATP. This process allows cells to maintain concentration gradients necessary for various cellular functions.
Do substances in diffussion move with the concentration gradient?
Yes, substances in diffusion move from an area of high concentration to an area of low concentration, following the concentration gradient. This process continues until equilibrium is reached, with equal concentration on both sides.
What energy from the hydrolysis of ATP is used to drive substances across the membrane against their own concentration gradients?
The energy from the hydrolysis of ATP is used to drive substances across the membrane against their own concentration gradients through a process called active transport. This process uses ATP-powered molecular pumps to move molecules or ions from an area of lower concentration to an area of higher concentration, requiring energy input to overcome the concentration gradient.
Does active transport move molecules against their concentration gradients?
Yes, active transport is a cellular process that moves molecules against their concentration gradients, requiring energy in the form of ATP to pump substances across the cell membrane. This process allows cells to accumulate molecules or ions at concentrations higher than their surroundings, enabling them to maintain internal balance and perform essential functions such as nutrient uptake and waste removal.

Which process uses proteins to move molecules against a concentration gradients?
active transport
The transport in which substances move from lower to high concentration is what?
Active transport is the process in which substances move from an area of lower concentration to an area of higher concentration, requiring energy in the form of ATP to drive this movement. It allows cells to accumulate nutrients and expel waste products against their concentration gradients.
Is the movement of substances against their concentration gradient an active or passive process?
The movement of substances against their concentration gradient is an active process.
Diffusion is important in body fluids because it tends to?
equalize concentration gradients, allowing for the movement of molecules from areas of high concentration to low concentration. This process is crucial for maintaining proper balance of nutrients and waste products in body fluids, ensuring proper cell function.
Does not require such an energy expenditure and occurs spontaneously?
The process you are describing is "passive transport," which moves substances across a cell membrane without the need for energy input. This can occur through processes like diffusion and osmosis, driven by concentration gradients.
In which type of process do substances move down their concentration gradient across the membrane?
Active transport is a process that removes substances from a cell against the concentration gradient. The molecules move from low concentration to high concentration during this process.
What process moves materials through a cell from areas of low concentrate to areas of high concentration?
Active transport is the process that moves materials through a cell from areas of low concentration to areas of high concentration by utilizing energy in the form of ATP. This process allows cells to maintain concentration gradients necessary for various cellular functions.
What name is given to the process by which substances pass into or out of a cell from an area of higher concentration to an area of lower concentration?
diffusion
Which cell process will remove substances against a concentration gradient?
Active transport
