004 Ion Channels: Proteins in the Membrane of Neurons

[GoldenPhoenix1981]

Is it right to believe that the passive ion channels are a form of diffusion?

Lectures in college are terrible. I learn more in a 10minute video than the whole year in college something is not right I am basically paying tuition fees to write exams because I learn nothing. Thank God for great online teachers like you. Sighs

tx very much for the great vids// very easy to understand

[RoxasX58]

Hey :) Which cell membrane was the diagram referring to, is it a cell of the skin, or a nerve or something else?

THAAAAANK YOUUUUUUUUUUUUUUUUU!!!!!!!!!!

[InteractiveBiology]

@xamandaxgatewayx You're veeeerrrry welcome :) Keep on coming back for more new Biology video uploads.

[justin505k]

I learn more in this 6 min video then a week for my bio teacher

[InteractiveBiology]

@justin505k Wow! That's so nice to hear :) Glad that we're able to help. Thank you! Stay tuned. We have more Biology videos coming very soon :)

[zai4booc]

I swear you deserve A NOBEL PRIZE FOR THESE VIDEOS OF YOURS :)

[InteractiveBiology]

@zai4booc That would be an honor for Leslie, LOL! Thank you for watching. Glad you're finding value in them. Stay tuned for more :)

[mprcb28]

you are my savior leslie.. !!! ur vids are great.. mwahkss

[InteractiveBiology]

@mprcb28 Glad to be able to help. All the best!

[waksibra]

this all seems pretty ungodly to me...

[fazieeBEE]

i dont really understand volted gated ion channels :O can you explain please! thanks!

[InteractiveBiology]

@fazieeBEE Try watching the video multiple times. I don't think I could explain it better in the comments than it's explained in the video.

[diamond61789]

Great video, very helpful!

[InteractiveBiology]

@diamond61789 Thank you. Glad to help!

[MyBestString1]

I love this channel too! Thanks Leslie for making A&P easier to understand. More power! I'm your fan!

[InteractiveBiology]

@MyBestString1 You are very much welcome :)

Glad you are finding the videos useful!

What happens at 3:50 does phosphate add to ADP and become ATP? Or is it the other way around so it consumes phosphate?

[InteractiveBiology]

@Lcakaelsie ATP is USED by the Na/K pump, and that involves ATP being broken down to ADP and an inorganic phosphate. That gives the pump energy to move the NA+ and K+ against the concentration gradient. Hope that helps! All the best!

[Rathanasan]

Thanks! What about Mechanically regulated channels and chemically gated channels? (How many channels are there?)

[InteractiveBiology]

@Rathanasan I have examples of those in some of the other episodes. Check out my channel and search for the following titles:

The Role of Hair Cells in Hearing - Episode 40 (Examples of Mechanically regulated)

Two Types of Receptors - Episode 17 (Examples of chemically gated)

The number of channels vary from neuron to neuron so I can't give a definite answer to that. Stay tuned for more videos :)

[dimabbq]

i love expanding my mind when i'm high, great vid

[InteractiveBiology]

@dimabbq Wow. Hey, learning is fun even when you aren't high :D

[dimabbq]

@InteractiveBiology the two do go well together i find

[oncrack87]

:) thanks!! very helpful!

[raenmaxi]

WOW I love this video, he makes it so much easier to understand!!!

He needs to be my instructor

[vtabano]

this is the best :)

[InteractiveBiology]

Glad you guys are finding value in it. All the best and stay tuned for more :)

[1shikela]

WOW this was great for my Anatomy class!!

[PlethoraXofXThoughts]

Great video. Very clear and concise...unlike my current neurobiology teacher -.-

[tabarca76]

Good job Leslie!
