Sodium ions are actively transported out of the epithelial cells by the sodium-potassium pump into the blood, this takes place in one type protein-carrier molecule
There is now a much higher concentration of sodium ions in the lumen than inside of the epithelium cells
The sodium ions diffuse into the epithelial cells through a different type of protein carrier, as the sodium ions flood back in through this second carrier protein they couple with te glucose molecules which are carried into the cell with them
The glucose passes into the blood plasma by facilitated diffusion using another type of carrier

Did thomas mifflin play an active or a passive role?
He played an active role.
What roll does cellular energy play in active transport?
radation
Why men are active and women are passive in sex role play?
If that is how it is it's because that particular couple chose their fantasy to be that way. There are other who prefer the opposite and some are both active. It's a fantasy, a role play so people can decide whatever they wish.
Where is ciliated epithelium found and what role does they play?
It helps with absorption and mobility
Can you explain the structure and function of semipermeable membrane and phosolipid bilayer?
A cell membrane is composed of a double layer of phospholipids, more commonly referred to as a phospholipid bilayer, and each phospholipid itself is important to the structure and function of the cell membrane. The head of a phospholipid is hydrophilic, attracting water, the two tails are hydrophobic not attracted to water. This means that water can pass through the cell well by passive transport, as the hydrophilic heads draw the water towards them and the hydrophobic tails push the water through the membrane to the other side. The tails of the phospholipid also play an important function, as the chinks in the tail allow the membrane to be fluid and allow substances to pass through (if they do not require active transport).

Change from active voice to passive voice does he play football?
Football is played by them
What roe does the cellular membrane play in active transport?
awesome stuff
What role does active transport play in diffusion?
active transport is kind of like diffusion, but unlike diffusion, it requires ATP(energy) and the molecule moves from low concentration to high concentration
What is the role of the electrons in the ETC?
Active transport is moving substance against its gradient so it requires an input of energy to achieve this. One example is Na K ATPase. This is a secondary active transporter that pumps 3x Na out of the cell for 2x K into the cell. There are so much more Na outside the cell and already a lot of K inside the cell so to push the molecules there is an expenditure of ATP to do this.
Change from active voice to passive voice you play football?
Football is played by you . I'm not sure that is correctly ... but i think it is )))
What role does a membrane play in active transport?

What is the difference between a passive park and an active park?
As a Supervisor of parks for a municipality, I can answer your question. A "Passive Park" is a public area designated as a park, but does not afford facilities or equipment for exercise or play: i.e a nature park or greenspace. It can have benches or trails, but is not conducive for for any "Active" use, such as sport or play. Just reverse that and you have the definition of an "Active" park.

What is the mechanism of water absorption in plant?
The mechanism of absorption of water is of two types:active and passive often operating independently . In active mechanism, water is absorbed by the force developing in the root system.Active absorption generally takes place in slowly transpiring and well-watered plants. In passive absorption mechanism, the forces responsible for the absorption of water develop in the shoot system, which are ultimately transmitted to the root system.The roots play a passive role in this mechanism. Passive absorption is, generally found in rapidly transpiring and ill-watered plants.Active absorption of water:Two types of theories such as osmotic theory and Xon Osmotic theory have been proposed to explain active absorption of water by plants.(i) Osmotic Theory:The ostomatic theory explains that the root hairs act as ohmmeters and there exists a typical condition so that water can move across osmotic ally from the soil solution to the root xylem.The theory assumes that translocation of water takes place by means of diffusion along a gradient of decreasing water potential or increasing solute potential . Absorption of water means translocation of water from soil solution to the xylem of root.The xylem sap, according to this theory, possesses a higher osmotic potentiality thin that of soil solution. So water moves from the soil to the root xylem by cells to cell osmosis. Because osmosis is a function of living cell, this process of osmotic water absorption is included under active process.(ii) Non osmotic theory:The non-osmotic theory assumes that when the driving forces are zero, water absorption takes place at the expenditure of metabolic energy released in respiration. Thus this theory explains the absorption of water by roots when the osmotic potential of soil water is greater than that of the root hair cell sap.The non-osmotic active water uptake can also be supported by the following facts:(i) There is a correlation between the rate of water absorption and respiration,(ii) Auxin-induced water uptake(iii) The factors such as low temperature, oxygen tension and respiratory inhibitors which affect respiratory rate and in turn the absorption rate.The serious draw bck of the above theory is that it fails to explain the exact manner of utilization of metabolic energy in the process of water uptake.
