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.
Why does active transport require more energy than osmosis or facilitated diffusion?
Active transport requires more energy than diffusion this 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.
Does osmosis increase free energy in a system?
No, osmosis does not increase free energy in a system. Osmosis is a process where solvent molecules move from an area of low solute concentration to an area of high solute concentration, but it does not directly affect the free energy of the system. The free energy change in osmosis depends on the pressure and temperature of the system.
Active transport is the process of what?
Active transport is the process by which a cell uses energy to move molecules or ions across a cell membrane against their concentration gradient. This process requires the use of ATP energy to pump substances from an area of low concentration to an area of high concentration.
Which requires the use of energy to move a molecule across a cell membrane?
No. Water molecules can osmotically cross the cell membrane because they are small enough that their polarity does not matter. Then there are porins. Channels across the cell membrane that water molecules use.
What is energy to compress gas?
When you compress a gas, you are increasing its pressure and decreasing its volume. This requires an input of energy to overcome the repulsion between gas molecules as they are forced closer together. The amount of energy needed depends on the volume of gas being compressed and the pressure to which it is being compressed.
What process is described as being the net movement of water molecules from an area of low concentration of solute to an area with a higher concentration of solute?
Osmosis
How does the motion of molecules contribute to heat being a form of energy?
The motion of molecules creates heat energy because as molecules move faster, they collide with each other and transfer energy in the form of heat. This movement and collision of molecules generate heat energy, making it a form of energy.
How is wind energy and thermal energy related?
Both are the inertial energy of moving molecules. Thermal energy being random and wind energy being more ordered in direction.
What is the definition of osmosis?
The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. Passive transport is the movement of a substance across a cell membrane with its concentration gradient (from high to low concentration) and it uses no energy. Osmosis is a special term used when water is the substance being moved.
Does Freezing require the removal of energy?
Yes, freezing requires the removal of energy from the substance being frozen in order to lower its temperature below its freezing point. This removal of energy causes the molecules to slow down and eventually form a solid structure.
Is active or passive transport involved?
In active transport the ATP is used to pump molecules up the concentration gradient. Transport of molecules occurs from a low concentration of solute to high concentration of solute and requires cellular energy. While passive transport involves carriers, channels, or direct diffusion through a membrane.
