What is the difference between active transport and passive transport mean?
Passive transport is a form of transport that does not require an input of energy. Examples include diffusion, osmosis and facilitated diffusion. On the other hand, active transport is a form of transport that requires an input of energy in the form of ATP (adenosine triphosphate). This energy is required for processes such as moving molecules against the concentration gradient.
Is a carrier protein an active transport or a passive transport?
They are used in both, in passive the molecules move in , then change the shape then leave and the entering and leaving are both by diffusion. in active transport molecules move in by diffusion, change the shape of the carrier protein, then because theyre moving into the cell where the molecule is in higher concentration energy is required to push the molecules out of the carrier proteins, this energy comes from ATP which is supplied to the carrier proteins.
What is the natural tendency of molecules to spread from an are of high concentration to low concentration?
Diffusion. If this happens to a water molecule, it is called osmosis. Moving from lower to higher concentration requires active transport.
What is the function of active transport in moving small molecules and ions across cell membranes?
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.
What is the process in which molecules move across the cell membrane from a region of low concentration to a region of high concentration?
Active Transport - the process of moving particles across a cell membrane against a concentration gradient <- right one
What type of passive transport involves water molecules moving from high to a low concentration?
osmosis
Which of the following types of passive transport involves water molecules moving from a high concentration to a low concentration?
Diffusion process
The movement of the smoke through the air is an example of what type of transport?
Smoke moving through the air is an example of diffusion. It involves matter moving from an area of high concentration of molecules to an area of low concentration of molecules. It does not require energy, so it is passive transport.
Why is energy needed for transport?
Molecules are moving against a 'concentration' gradient. Active transportation moving from low to high concentration, while passive transportation such as osmosis and diffusion go from high to low concentration.
How is active transport diffrent from osmosis?
Active transport occurs when molecules are moved from an area of low concentration to an area of high concentration. The cell membrane acts as a semi-permeable barrier during the process. Energy is required for active transport. Osmosis is a type of passive transport. Passive transport is similar to active transport except it requires no energy and molecules move from an area of high concentration to an area of low concentration. Osmosis occurs only if the molecules moving across the cell membrane are WATER molecules.
The transport in which substances move from lower to high concentration is what?
The textbook definition of "passive transport" is moving from high to low concentration. You mean passive diffusion..
Under what conditions will passive transport occur?
Mainly through the chemically quite simple process called chemical diffusion.
Is an electron transport chain passive transport or active transport?
passive transport since the protons are moving down their concentration gradient back into the mitochondrial matrix.
Compare active transport to passive transport?
Active transport requires energy, whereas passive transport does not. Passive transport is normally something moving from an area of high concentration to low concentration (with the grain). Active transport is something moving from an area of low concentration to an area of high concentration(against the grain).
In what process are carrier proteins important?
Carrier proteins is important in facilitated diffusion. Facilitated diffusion transports molecules from one area of higher concentration on one side of the membrane to an area of lower concentration on the other side .Because the molecules are moving down their concentration gradient , facilitated diffusion is passive transport.
What is the difference between active transport and passive transport mean?
Passive transport is a form of transport that does not require an input of energy. Examples include diffusion, osmosis and facilitated diffusion. On the other hand, active transport is a form of transport that requires an input of energy in the form of ATP (adenosine triphosphate). This energy is required for processes such as moving molecules against the concentration gradient.
What is passive transportation?
Passive transport is a means of moving biochemicals, and other atomic or molecular substances, across membranes. Unlike active transport, this process does not involve chemical energy. Passive transport is dependent on the permeability of the cell membrane, which, in turn, is dependent on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. An example would be osmosis; in osmosis, water molecules move from an area of high concentration to an area of low concentration. Carrier proteins are sometimes used during passive transport.
