To answer your question Mr.Poser, Tetrodotoxin interferes with the transmission of signals from nerves to muscles by blocking sodium channels. This results in rapid weakening and paralysis of muscles, including those of the respiratory tract, which can lead to respiratory arrest and death.
That’s what it is! Thank you!
Hello Mr. Poser, I just want to say thank you so much for being such an amazing teacher and helping me prepare for all of my AP exams, I have my AP exam tommorow with biology and this is helping me big time with review! Thank you so much.
I'm glad to help! Go get em!
Can you finish all of the recap units before the AP Exam? Your videos have been super helpful! Especially these recaps for this AP bio midterm exam that is tomorrow. I want to say thank you for helping me get an A in AP Bio :)
I’m gonna try really hard! And I’m so glad I can help! 😁
Thank you for this
Of course!

That’s the plan!
Do you think you can do practice questions at the end of each module? Thank you
As in some practice FRQ's? Sure! I'll probably do those in separate videos, though.

Tetrodotoxin blocks sodium ion channels! Thanks for the reminder
This is a nit, but a positive feedback loop should probably be referred to as a virtuous cycle rather than a vicious cycle.
That makes sense! I’d only ever heard of vicious cycles being like this before so thanks for the insight
I appreciate the excellent service you are providing not just for your students but for people everywhere who want to learn about biology. Thank you!
