What moves across the membranes by osmosis?
Solvent
Generation of proton gradients across membranes occurs during what?
Generation of proton gradients across membranes occur during both photosynthesis and respiration. The reduction of oxygen which forms water occurs during respiration.Ê
Is osmosis a form of diffusion?
Yes. Osmosis is a special case of diffusion - in involves just water diffusing across a semipermeable membranes - like in cell membranes.
What is the role of ATP in sodium-potassium pump?
transport across the membrane
Why is a potassium sodium pump needed?
The process of moving sodium and potassium ions across the cell is an active transport process involving the hydrolysis of ATP to provide the necessary energy.
What is actively transported across plasma membranes?
name of the substance that is actively transported through the cell membrance of an animal cell
When Fatty acids are hydrolyzed they yield what?
transported across fat cell membranes by fatty acid binding proteins
Why does the membrane have to pump sodium and potassium across the membrane and keeps pumping it?
The membranes of nerve Cells use the Sodium/Potassium pump system to charge It's membranes, for a reversal of this condition constitutes the discharge of this Action Potential - 'keeps pumping it' refers to recharging the membrane's Action Potential.
Why does water require channels to be transported across the membranes?
Water doesn't require channels to be transported across membranes because water is small enough to slip past the membrane; however, some cells do have channels, called aquaporins, which greatly increase the rate that water passes through the membrane.
What theater was transported across the thames river?
The Theatre it was transported across to create the Globe
How charged partiles like Na and K move across membranes?
Through Sodium-Potassium Pump Proteins. They are the key to a successful action potential, and eventually an impulse
How do larger molecules move across epithelial membranes in the capillaries?
Large molecules are transported across a cell membrane by the process of process of exocytosis. This is when secretory vesicles secretes large molecules by the fusion of vesicles with the plasma membrane.
A transporter protien that carries a substance across a cellular membrane against its concentration gradient?
Sodium potassium ATPase pump.
How is water transported across the membrane?
Water is transported by a passive transport called osmosis. Osmosis is diffusion of water across the membrane.
Generation of proton gradients across membranes occur during?
Generation of proton gradients across membranes occurs?
What moves across the membranes by osmosis?

How can coal oil and gas be transported across the ocean?
they can be transported by tankers which are like boats.
