031 How Rods and Cones respond to Light

http://www.interactive-biology.com - In this episode, I go through the process of how rods and cones respond to light. I use Rods as an example and show how Rhodopsin, Transducin and Phosphodiesterase are involved in the process. Enjoy

Interesting and well done video. But I miss some details to the reactions happening in the rods. For example the fact that the whole process is a cascade.

Hi, thank you for watching. Leslie will be uploading more videos by next year. He just might or might not tackle this topic again with more clarifications. Please stay tuned for more!

[Ckaotenkind]

Thank you a lot. I'm from Germany and although the videos are in english I understand it very well. You rescued me for my biology test tomorrow. And now I will be able to write it in english :) Unfortunately my teacher won't understand one single word. THANK YOU, it's very well explained

[InteractiveBiology]

Well, we're glad to know you've gained something from it. We hope you aced your test. Stay tuned because we have new Biology videos coming very soon :)

Can't wait for that video. I remember this video was why I subscribed. You really saved my day!

[InteractiveBiology]

THank You! Keep on watching :) We'll have more added to the site very soon!

Dude the fovea doesn't have a lot of rods

[Reotshepile Kgoro]

Wow this video helped me a lot and i really appreciate it... GOD bless you

[Dennis Don Karunakaran]

Bless you Sir! Thank you

Excellent video series. Not certain why persons are being so critical, when they are clearly made to give students a general understanding. Thanks, You've helped sooo much!

one major mistake, its 11-cis retinal. 11-cis retinol is an intermediate which is formed in the transformation from 11-trans retinal back to the light sensitive 11-cis retinal.

Fabulous clip. Youtube is great for this type of thing.My good friend was previously bullied. He said he was planning to get bigger muscle mass. I chuckled... Then he gained 40lbs of absolute muscle mass. He tried the Muscle Building Bible (Google it). No person dares to intimidate the man now. :) I actually signed up a few days ago. See what will happen. Not to mention the guys emails are cool!

It would be nice to also visually explain how, say, a 450nm(blue) photon, striking a blue cone activates the chemical reaction explained in this video, and exactly WHY a 550nm (green) photon would not induce the reaction in a blue cone. I suspect the chemicals present only in a blue cone absorbs a photon of strictly ~450nm due to this chemical's natural vibration frequency, which only responds to (or synchronizes with) light that carries photons of the same electromagnetic vibration frequency.
