Dark reaction is also known as light-independent phase. Unlike, light reaction, it does not require light as an essential factor. Thus, can takes place both in the presence or absence of light. The term dark reaction does not mean that it takes place only in dark period or at night. CO2 fixation occurs in both C3 and C4 cycle. In C3 cycle, CO2 is added by the enzyme, RuBisco to a 5 carbon compound RuBP that is converted to 2 molecules of 3-carbon PGA. In C4 cycle the first product of CO2 fixation(takes place in mesophyll) is a 4-carbon compound, oxaloacetic acid. It is seen in some tropical plants.
Bhai tu bol rha light reaction me light imp nhi hota toh .... Tu energy kaha se lega , sun se hi lega na ..... Aur jo lumen of thalakoid me h2o breakhoga wo in presence of light me hoga 😅
Ma'am please teach all the chapters of plant physiology . Please please please please please You teach very well . You are the best teacher of biology.😘 I love you ma'am ❤️
mam, I want to comment but I can't because words are not enough to appreciate your talent and hard work may God bless you as, you have blessed many students by your teaching method.
I have gotten full concept of c3 cycle very clearly.Your learning method is excellent. As I read in class 11 ,these lectures have removed my all doubt🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗🤗
I am in 10 now . Today our teacher taught this c3 cycle and everybody was confused . But me being ritu mam's student I was able to answer his questions .
oooh mam.kya bola hai...seriously itna bdia explnation of h+ from lumen to stroma and then to NADP then to the calvin cycle and then to glucose... wow mam. mtlb kya kahu sach mein speachless ho gae. i thank god ki muzhe apke channel ke bare mein pata chala. thank you mam for making it as clear as a crystal..
Temp. does affect light reaction (as you said, due to the usage of NADP reductase), but if you see detailed C3 cycle, you'll see it's a hugely complex and long cycle, involving a whole lot of enzymes. Thus it's temperature sensitivity increases as compared to light reaction. Hope I helped, and in time. Best of luck for NEET!
H+ ions formed from photolysis of water are present in stroma which are then used by NADP to form NADP'H+' . This 'H+' from NADPH is used by CO2 in C3 cycle for production of glucose !
Big fan from Pakistan...you are really awesome and fantastic teacher I completing my full course from you so I got more better concept..God bless you mam
the only teacher jisse padhkar kabhi boring nahi feel hota ek din me aapki vajah se bohot chapters complete ho rahe maam i m so blessed to be your student ❤👍
Genuinely mam.... The way you untangle the concepts simply and your facial expressions to make us feel the same to get that feel just to understand that thing from your tangent.... Seriously mam you are matchless..💯 💯
After studying bio from Ritu ma'am ....I just feel ... Ma'am se agar biology smjh nhi aaya to iss puri duniya mein in the whole World kisi se samjh nahi aane wala❤❤❤❤
Ma'am really taught great and I understood the topic completely but one small mistake ( pls don't mind anyone for pointing it) that ma'am made while teaching I.e. it's ribulose bisphosphate and not biphosphate. I thought to tell it because it can cost u if u don't know the correct thing during competitive exams as every number of each question there counts. Hope , anybody will not take in a wrong way because I'm neither disrespecting or abusing ma'am as I'm not eligible also to do that . Thank you
Hard topic ko easily samjhate hai

He is talking ABOUT DARK REACTION
@@luckyjaiswal1854 but jb tk darkness hogi tb tk tw kaafi hydrolysis ho chuka hoga h positive ions hngy hi.. tw phir no need of light for C3 cycle
best bio teacher in whole world.jitna bhi thanx bolo utna kamm h realy sb samajh aa jata h mam apkii class m. thank you mam a lot

20:52 #ERROR ,Light reaction also involves enzymes like NADP synthase ,Then how Temp Can't affect it....
Aapne hi bataya tha...so puchaa...

First plant physiology was like areoplane but after watching class it become paper rocket❣️

Nice lecture, and damm good, this is the way of conceptual teaching and conceptual learning by students
