What else can I help you with?
Proceeds Against a concentration Gradient requires a carrier?
Yes, the movement of molecules against a concentration gradient requires the use of a carrier protein or active transport mechanism in order to transport the molecules from an area of lower concentration to an area of higher concentration. This process requires energy to move molecules against their natural gradient.
Why does active transport require more energy than osmosis or faciliated diffusion?
It is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
Facilitated diffusion and active transport?
Facilitated diffusion is the passive transport of molecules across a membrane with the help of transport proteins. This process occurs down the concentration gradient and does not require energy. In contrast, active transport requires energy to move molecules against their concentration gradient through specific transport proteins.
When a cell membrane protein moves a solute in the opposite direction as the concentration gradient?
The process is known as active transport. It requires energy in the form of ATP to pump the solute against its concentration gradient. This allows the cell to maintain internal concentrations different from its external environment.
What does it mean when you are going with the concentration gradient?
Going with the concentration gradient is basically the process of diffusion. Molecules going from a low concentration to a high concentration would be going with the concentration gradient. Going against the concentration gradient would be the movement of particles from a high concentration to a low concentration
What is the energy source for co-transport?
The energy source for co-transport is typically the concentration gradient of one substance that is established by an active transport process. This concentration gradient drives the movement of another substance against its own concentration gradient through a symporter protein.
What is active absorption?
requires the input of energy and a carrier protein to move nutrients across a concentration gradient

What is essential for diffusion?
A- A Concentration Gradient B- A Selectively Permeable Membrane C- A Source of Energy D- A Protein The Answer Is (A) Diffusion can occur without a semipermeable membrane, as diffusion is simply movement of a substance from high to low concentration. A source of energy is needed only for active transport. Proteins are needed if the the particles transported are too big to pass the semipermeable membrane.
When a cell membrane protein moves a solute in the opposite direction as the concentration gradient?
The process is known as active transport. It requires energy in the form of ATP to pump the solute against its concentration gradient. This allows the cell to maintain internal concentrations different from its external environment.
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.
How does the Concentration gradient of a substance affect the movement of that substance and the expenditure of energy?
A concentration gradient of a substance drives the movement of that substance from an area of high concentration to an area of low concentration. The steeper the concentration gradient, the faster the movement of the substance, requiring less energy to transport it. If the concentration on both sides of the gradient is equal, there is no net movement of the substance.
What does it mean when you are going with the concentration gradient?
Going with the concentration gradient is basically the process of diffusion. Molecules going from a low concentration to a high concentration would be going with the concentration gradient. Going against the concentration gradient would be the movement of particles from a high concentration to a low concentration
What must happen when a concentration gradient is eliminated?
When a concentration gradient is eliminated, there will be no difference in the concentration of a substance across a region. This can lead to equilibrium, where molecules are evenly distributed, or in the case of active transport, energy may be required to maintain the concentration gradient.
What term defines the movement of materials along concentration gradient through channels?
Facilitated diffusion defines he movement of materials along a concentration gradient through protein channels.
