[@JoaosLab]

Glad it was helpful! 🙌

[@anyfriendofkevinbaconisafr177]

Great information, well organized, and good visuals! The narrator is always speaking with a high-pitched high-energy which became tiring. It was as if every point was equally the most important thing to know and I felt like I was simply memorizing without gaining insight. But that's just one aspect of a basically very good video. Thank you❤

[@JoaosLab]

Thank you very much for your feedback! I will keep it in mind for the next videos. I have tried videos with a lower pitch, and I thought they didn’t work so well. Some people like this high-energy approach, others don’t. And that’s ok too! 😊 We can’t be everyone’s cup of tea.

[@Serenity.Sounds263]

You also said smooth ER in the adrenal gland secretes cholesterol which is a precursor of steroid hormones. What does the precursor mean. Please explain this points more. thank you

[@JoaosLab]

By "precursor", I meant to say that cholesterol can become a steroid hormone.

[@mrpotteryt9800]

Thank u sir its very helpful😊

[@treasureordinioha4206]

Hello The smooth ER is mainly located near the cell periphery. Please what do you mean by the cell periphery

[@JoaosLab]

By "cell periphery", I mean towards the cell membrane. I hope this clarifies this point for you. 🙂

[@AmanitaWoodrose]

I've always thought Australian aboriginal art to be v reminiscent of ER, ribosomes, nuclei etc.

[@MarjoreOesch]

This is great! Would it be possible for you to take out the word "hell"?

[@JoaosLab]

Thank you, Marjore! Unfortunately, I cannot. Is there any reason why you would like us to remove the word "hell"?

[@AsadZahid-fr4lr]

This is for you 💗 subscribe 😊

[@lucygooseAZ]

Is it possible that protein synthesis occur in the smooth ER? Instead of it happening in the rough ER.

[@dhaneshmanvar3599]

No Ribosomes are needed for making proteins and Smooth ER doesn't contain it.

[@oliviatoma61]

🤗

[@yagmurcamd]

Process,

[@allizzwell178]

Ribosomes are not membrane bound.Lest the presentation is beautiful...

[@JoaosLab]

By membrane bound, I meant to say that ribosomes are attached to the ER membrane. :)
