Carotenoid --> Vit A --> retinol -->retinol palmitate--> retinal --> 11cis retinal --> binds to rhodopsin and iodopsin in cones-->all trans retinal due to light-->back to 11 cis retinal

Ma'am thanks for this lecture.Learnt better than in my actual class.

The lec was really helpful...u r BEST teacher👍🏻❤️

You are the best!

thank you mam, you are very amazing mam,from this lecture many students including me increase our knowledge, you teach better than our subject teacher in my opinion. We are very lucky to have you as a teacher. We pursue many videos on youtube but we forget about these type of video . So if we want to increase our knowledge we must watch these videos rather than the entertainment base.

Thank u ma'm

Really helpful mam 👍🏻

Very helpful 🙂👍

I dont understand clearly. Why both rhodopsin (in rods) and photopsin (in cones) are created by retinal (vitA). But people who lack of vitA only have night blindness. Why they see well on day? Thanks!

Ma'am pls upload forensic plsss my exams are there😭😭
