What process uses proteins to move molecules against a concentration gradient?
Active transport is the process that uses proteins to move molecules against a concentration gradient. This process requires energy in the form of ATP to pump molecules across the cell membrane, enabling cells to maintain specific internal environments different from their surroundings.
What homeostatic process maoves particles against a concentration gradient?
passive transport
How is facilitated diffusion different from avtive transport?
Facilitated diffusion is a passive process where molecules move across a membrane with the help of transport proteins, following the concentration gradient and requiring no energy input. Active transport, on the other hand, is an energy-requiring process that moves molecules against their concentration gradient using ATP or an electrochemical gradient.
What does active transport requires?
Active transport requires the use of energy, usually in the form of ATP, to move molecules or ions across a cell membrane against their concentration gradient. This process is essential for maintaining cell functions and often involves specific transport proteins or pumps.
How can a cell transport a substance from lower to higher concentration?
A cell can transport a substance from lower to higher concentration through active transport, which uses energy to move molecules against the concentration gradient. This process typically involves the use of specialized proteins in the cell membrane to pump the molecules against the concentration gradient.
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.
What is the name of the process of water moving from a higher concentration to a low concentrarion?
"osmosis"
How do cells transport molecules against their concentration gradient?
Cells transport molecules against their concentration gradient through a process called active transport. This process requires energy in the form of ATP to move molecules from an area of low concentration to an area of high concentration. Proteins embedded in the cell membrane, such as pumps and carriers, help facilitate this movement.
Active transport always requires transport proteins during the process?
false
What process is used to go against the concentration gradient?
active transport
What process uses proteins to move molecules against a concentration gradient?
Active transport is the process that uses proteins to move molecules against a concentration gradient. This process requires energy in the form of ATP to pump molecules across the cell membrane, enabling cells to maintain specific internal environments different from their surroundings.
How does the process of active transport enable the movement of molecules against their concentration gradient?
Active transport is a process in which cells use energy to move molecules against their concentration gradient, from an area of low concentration to an area of high concentration. This is achieved by using specialized proteins called pumps that actively transport the molecules across the cell membrane. The energy required for this process is usually provided by ATP, the cell's energy currency.
Does active transport require transport proteins?
Yes, active transport does require transport proteins. These proteins use energy to move molecules against their concentration gradient, typically from an area of low concentration to high concentration. This process is essential for maintaining cellular homeostasis.
What process moves sodium ions?
Sodium ions can be moved across cell membranes through the process of active transport, which utilizes energy from ATP to pump ions against their concentration gradient. Sodium ions can also move through facilitated diffusion, where they move down their concentration gradient with the help of transport proteins.
Which cell process will remove substances against a concentration gradient?
Active transport
What homeostatic process maoves particles against a concentration gradient?
passive transport
