I learned more from this 6 minute video then I did from 3 90 minute clases.

[@BOGObiology]

Glad it was helpful! To be fair, if I taught all this same content in a traditional (read "lecture style") way, it'd probably take at least 2 90 minute class periods. You spend a LOT of time waiting for students to write down what you're saying, and the kid that's the slowest writer often doesn't get everything. Yet another reason why I hate lecturing.

[@lukendiadussuau866]

I was very helpful, simple, clear, and easy to understand. I will definitely consider this site as my second Biology Class.

I'd say that's true for about 50%, based on the demographics data I have. Doesn't explain why there are 60 year olds watching, though!

Thankyou so much! I don’t often comment on KZbin videos but this was so good. Straight to the point, clear, and I loved the visuals. I understood everything straight away, unlike in school where I somehow don’t understand anything in a whole lesson. Please keep making videos just like this! Particularly the visuals such as when it shows the movement of particles between the cells etc. thanks again

[@BOGObiology]

Thanks, Andres! Appreciate you taking the time to write such a thoughtful comment! Sometimes it's just a matter of seeking out the same information but portrayed in a different way. Sending love and best wishes from Boston! -BOGO

[@vivihihi8020]

We have an exam ond I had a extremely mess in my brain about the differents between passiv and active transport, but now I understand it. Thank you soo much for that video!!

Thanks, Jacob! Please share with your classmates! If you thought the class explanation was confusing, they definitely did, too. And, maybe, they'll pay it forward and share good resources with you in future. Sending best wishes from Boston! -BOGO

[@BOGObiology]

Glad it was helpful! I had fun making this video

[@Lala-Lander]

Hello from India! You make awesome screencasts. I had to subscribe. And your videos made me purchase the vittle app. But I can't figure out how to animate stuff. I get how you draw that cell membrane with Na+ K+ pump, but how you animated those blinking eyes and that green carrier protein baffles me. Do you do voice over? If so what app do you use? Do you write your scripts? Do you edit entirely on your iPad? Could you please let me know the complete step by step process involved in making your videos? Or else I'll have wasted my money on the vittle app and the time trying to figure out on my own. You already did a couple of videos on how you work, but you know, I'm lost...

[@BOGObiology]

Hi Zeelit! Greetings back from Boston! Glad you like the screencasts; I have fun making them! I used to do everything all at once in vittle; I'd draw and talk at the same time. However, I discovered that I drew better when I wasn't talking and I could talk more easily when I wasn't also drawing. You can see what a difference it makes if you look at some of my old videos; they're messier and have lots of background noise. Here's my process these days: 1) Decide on a topic, do tons of research, keeping a list of sources. 2) Write an outline. 3) Make the outline into a script. 4) Realize that the script would be a 20 minute video, edit it down to 10-15 mins 5) Do all the drawing and animating in vittle. 6) Export the vittle MP4 file to iMovie. 7) Record the voiceover as the final step. As for the animating I've found a couple ways to "animate" in Vittle, they're listed below from easiest to hardest with links so you can see what the finished product looks like. 1) Make things appear on screen. Record the blank screen, then stop the recording. Draw the new thing. Start the recording again, and in the film, the new thing will magically appear. (See: kzbin.info/www/bejne/mGLCoYqEiqmridE ) I use this the most, for sure. 2) Make something move around: Select the thing using the selector tool, hit "record", move the thing around, then stop the recording. (See: kzbin.info/www/bejne/mGLCoYqEiqmridE ) 3) To make something "blink" (or a similarly simple motion) I hit "record" with its eyes open, then quickly stop the recording. Then I pop a set of closed eyelids over the eyes, and hit quickly hit "record" again. Finally, I remove the eyelids and hit "record" quickly again. Vittle has now taken a quick snapshot of eyes open, eyes closed, and eyes open again, so it when it plays it looks like the little dude is blinking. (See: kzbin.info/www/bejne/mGLCoYqEiqmridE ) 4) To gradually change something over time, I treat Vittle like stop-motion. I record for a quick second, stop the recording, make a small change, then hit record again, then stop it. Repeat, repeat, repeat. When you speed it up, it looks like continuous motion. (See: kzbin.info/www/bejne/mGLCoYqEiqmridE&t=210 ) The stop-motion effect looks awesome, but it takes forever to do, so I only use it for really important things that can't be done with the other methods, like showing the conformational change of the Na-K pump! Hope this helps, and PLEASE let me know if you find other ways to make the videos come alive! I'm always looking for new ideas. Love, BOGO

[@Lala-Lander]

@@BOGObiology Thanks a lot. That was so caring of you to reply so soon and explain in such details. Hope I'll do fine. I'm off to practicing. Lots of luv!!!

[@BOGObiology]

@@Lala-Lander My pleasure! The important thing is for you to find a strategy that works for you and is enjoyable for you, you certainly don't have to copy what I do exactly. I'm sure, after some tinkering, you'll find other, clever, strategies that I've never thought of. And when you do, I hope you'll share! Stay safe out there! Love, BOGO

[@mbutterfly110]

Your delivery (visual & audio) are great.. only thing that would make it perfect (from a non-scientific, in fact struggling enthusiast's trying to catch up mind!) is if it was just on a tad bit SLOWER rate... so I could at least absorb a bit of this great firehose of knowledge! ☺️🙏🏼.. but like 👍🏼 your KZbins way better than my biology instructor's jumping around all over the places, ending up in organic chemistry instead of Biology!! Anyways.. Thank you 🙏🏼

[@danunugraha2696]

what series of iPad for making this kind of video? do you use apple pencil or 3rd party stylus?

[@BOGObiology]

Hello! This is a 2017 iPad (regular not pro) using the app Vittle. For drawing, I use an elago stylus. I like it because it has sides to it like a pencil, and is made of metal so it's got some weight to it. I also like that you can replace the rubber tip when they wear out, and they're relatively inexpensive. www.amazon.com/elago-Stylus-iPhones-Replaceable-included/dp/B0052WESJ0/ref=sr_1_2?ie=UTF8&qid=1523133629&sr=8-2&keywords=elago+stylus

[@BOGObiology]

[@amritamallick4895]

Endocytosis at the postsynaptic neuron?? Please check the validity of this piece of information. To my knowledge, the neurotransmitters, esp. ACh, binds to postsynaptic receptors to trigger a signal transduction.

[@BOGObiology]

Ooooh! Great question. They do both! The post synaptic binding is what triggers the transduction, yes. However, post synaptic neurons DO perform endocytosis, it just takes a really, really long time relative to the normal conduction process and is related more to the "recycling" of materials rather than the actual propagation of the signal. Definitely check out the concept of clatherin mediated endocytosis. I obviously wasn't clear on that point, so thanks muchly for the feedback. If it helps, I like to consider what would happen to a neuron (or any cell, really) that ONLY performed endocytosis but never endocytosis. Assuming it could somehow generate a really big supply of vesicle material, as they repeatedly docked against the exterior wall and opened, the cell would just get bigger and bigger and bigger until... something? I suppose the limit would be when it got so big that diffusion wouldn't be effective for helping to saturate it with oxygen and other important materials and the cell died. Endo and exo usually need to be performed in roughly equal amounts, but science being the sloppy imprecise discipline it is, I'm sure there's an exception to this rule out there somewhere. I'll have a look. Love from Boston and thanks for a good mind-bend on a monday morning! -BOGO Here's a couple sources I referred to: elifesciences.org/articles/17692 www.mechanobio.info/what-is-the-plasma-membrane/what-is-membrane-trafficking/what-is-clathrin-mediated-endocytosis/#:~:text=clathrin%2Dmediated%20endocytosis%3F-,Clathrin%2Dmediated%20endocytosis%20(CME)%20is%20a%20vesicular%20transport%20event,uptake%20and%20synaptic%20vesicle%20reformation.

what is a vesicle?

[@BOGObiology]

A vesicle is a bubble of cell membrane surrounding something that needs to be kept separate from other things inside the cell, at least temporarily. Hope this helps! Love, BOGO
