Membrane transport lecture | transport across the membrane

Transport across the membrane - This video lecture about membrane transport explains about the basics of transport across the membrane. It explains different types of membrane transport mechanisms such as passive transport including facilitated diffusion and the active transport mechanism. It also explains about the role of membrane proteins both channel proteins and carrier proteins in process of cell membrane transport mechanism.

Well

[@zaheentaher4398]

Please make a vedio "lipid bilayer and membrane protein diffusion".
Or clear that what the read in "membrane protein diffusion"

[@botanyatoz5272]

On basis on metabolic energy consumption, transport is of following types
Passive (along conc, graadient..no energy used)
Passive = simple & Fascilitated diffusion
Active : against conc gradnt..so energy used
Active= primary avtive & secondary active

[@bhimsinhpadhiyar2816]

Please.....sir make a video on group translocation in membrane transport...

[@shomusbiologyofficial]

Okay

[@quratulan133]

12:53 uh told na needs to be taken outside
Bt at 14:28 uh are saying that na goes inside the cell ....these two points are totally opposite plzz sir reply is na going outside the cell or inside the cell sir plzz reply after 3 days it's my exams🙏🙏🙏

Sir you didn't mention the 3rd type of carrier protein.

[@botanyatoz5272]

Transporter protein are broadly of 3 types:
Channels : take part in Fascilitated diffusion only
Permeases or carriers: take part in Fascilitated diffusion and SECONDARY ACTIVE TRANSPORT.
Pumps: Take part in PRIMARY ACTIVE TRANSPORT only

Membrane protein also have hydrophobic domain in lipid bilayer then how it will allow polar molecules transport through membrane ??

Through transporters

Coupled tramsport
Co transport

[@davehileri7072]

😇😇

[@chandramaghosh3365]

I can not understand the coupled active transport part. If Na+ going down the conc gradient, it doesn't need energy, neither it produces energy. So what's the need of coupling???

[@catsandrandom3844]

Going against the gradient releases free energy, which can be utilized to transport molecules against the electrochemical gradient (charge of particles is also responsible for creating a charge gradient, so it's called an electrochemical gradient).

[@botanyatoz5272]

That's secondary active transport..
For details..search & watch Membrane transport and transporter protien types

[@aleixteixido8238]

Water diffuses through the membrane without a protein because it's a small molecule with no charge (despite being polar)

[@zulqurist]

Sorry water is hydrophobic and hence the the polar head is hydrophilic that is why water cannot diffuse easily hence need protein channel to pass out water into the cell

[@botanyatoz5272]

Water passes through special channels or pores called aquaporins

[@botanyatoz5272]

@@zulqurist ..water is lipidophobic.. not hydrophobic

[@BB-tf5wr]

?. Is there about epithelial transport
and thank you very much

[@Pushpinder_Singh_0610]

Baraa Mdalal No

[@botanyatoz5272]

Osmosis takes place through semipermeable.. she is right..
Osmosis means movement of solvent only..
That is what defines semipermeable membrane.. semipermeable memb alows movement of solvent only...
Selective permeable memb alows movement of both solven & solute (ions / milecules) but that is decided/selected by presence of concerned transporter protein..
Our cell membrane is selectively permeable

[@clawmercy]

Sir I'm confused between carrier and pump

[@shomusbiologyofficial]

Don't worry. Will clarify that in another video

[@clawmercy]

Ok sir
Thanks

[@botanyatoz5272]

Carrier/permease is synonym: Take part in Fascilitated diffusion & secondary active transport
Pump: Transporter protiens that operate only by using metabolic enrgy.. thetefore take part in PRIMARY ACTIVE transport
