Is plasma membrane is more permeable to K than Na during rest?
No, this is because the transport of K and Na ion across the plasma membrane require active transport and this require ATP.
What is aqua-protein?
an aqua protein is a channel protein which allows water to pass through a membrane during osmosis
What moves across the inner mitochondrial membrane to synthesize ATP during chemiosmosis?
protons
How water molucleus move through the cell membrane doing out mosis?
During osmosis, water molecules move through the cell membrane by passing through microscopic openings in the membrane. The openings are large enough for the water molecules to pass through.
Movement of a substance across a cell membrane using chemical energy occurs during?
active transport
What material diffuses across the cell membrane during osmosis?
Osmosis is the movement of WATER from an area of high concentration to an area of low concentration through a semi-permeable membrane. So water is exchanged during osmosis.
What takes place during osmosis?
Osmosis is the movement of water form its higher concentration to lower concentration through a semi permeable membrane. In it water can move from inside to outside or outside to inside.
What make osmosis and diffusion the same?
Molecules travel across the cell membrane from a higher concentration to a lower concentration during both osmosis and diffusion. Diffusion is when molecules move across the cells' membrane from a higher concentration to a lower concentration. Osmosis is the diffusion of water.
Explain how osmosis differs from diffusion?
Osmosis differs from Diffusion because in osmosis only water moves, and during diffusion, small molecules move across the cell membrane.
When does movement of a substance across a cell membrane using chemical energy occur?
During osmosis and uptake of minerals.
How are cells affected by osmosis?
The cell membrane does not move during osmosis. Osmosis is defined as "the net movement of water molecules across a semi-permeable membrane following a concentration gradient."
Where can a semi permeable membrane be found?
The cell membrane, this is because of the lipids that form it. They allow certain things through such as water during osmosis but block other things creating a need for things like protein pumps.
Describe the water molecules move through the cell membrane during osmosis?
Describe how water molecules move through the cell membrane during osmosis?
Is plasma membrane is more permeable to K than Na during rest?
No, this is because the transport of K and Na ion across the plasma membrane require active transport and this require ATP.
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.
What is diffusion of oxygen all about?
Diffusion is the main method by which molecules move across the cell membrane. during diffusion, molecules move from an area of higher concentration, to an area of lower concentration. What is Osmosis? Osmosis is the transport of water from an area of high concentration, to an area of low concentration water moves inside and inside of the cell membrane by osmosis. osmosis is the diffusion of water!
Osmosis always involves the movement of what?
Osmosis always involves the movement of water. During osmosis water will move in and out of the cell or membrane.
