no further revision required.. i once happen to watch one of ur videos while searching some content and now i depend on ur videos all the time.. Thank u so much mam for such helpful lectures.. u deserve all d respect 💜

Maam I realllllyyyy reallllyyyy from the bottom of my heartttt respect youuuu from the coreee....you are the only teacher on youtube on bio whose speech is clear...explanation is clearr...no bakwas....to the pointttttt clearing of all the topicsss!!!! Hatsss offff!!
Ur way of teaching is great..U always make us focus on concepts and always tries to make us learn the concept..U r just great mam..thanks for such wonderful lectures😊
its sad that all i can do is give a like and share. i wish i could do more i have watched all your vídeos of vegetal fisiology and scored na A+ thanks very much.
@@sumitamitra7029 5:33 I guess you're the one who needs to have a proper note. She has clearly written Ribulose for RuBis and Carboxylase oxygenase for CO. The correct one is Ribulose for Ru and bisphosphate for Bi and Carboxylase oxygenase for CO..

This is a wonderful platform to reach every corner and spread knowledge. Your lessons are just fantabulous. Keep it up ma'am.👏🙏 And thanks to RU-vid for providing such platform 👍👌
Wow wow fantastic,i have really gained all I needed this is well explained biology, we thank God for the gift in you of being able to explain with reasoning, WOW you are good Doc.
RuBP=Ribulose-1,5-bisphosphate RuBisCO=Ribulose bisphosphate carboxylase-oxygenase Rubisco catalyzes the reaction of RuBP with O2 or CO2 As its full name indicates, rubisco is an oxygenase as well as a carboxylase-it can add O2 to the acceptor molecule RuBP in- stead of CO2. The affinity of rubisco for CO2 is about ten times stronger than its affinity for O2. This means that inside a leaf with a normal exchange of air with the outside, CO2 fixation is favored even though the concentration of CO2 in the air is far less than that of O2. But if there is an even higher concentra- tion of O2 in the leaf, it acts as a competitive inhibitor, and RuBP reacts with O2 rather than CO2. This reduces the overall amount of CO2 that is converted into carbohydrates, and may play a role in limiting plant growth. When O2 is added to RuBP, one of the products is a 2-carbon compound, phosphoglycolate: RuBP + O2 → phosphoglycolate + 3-phosphoglycerate (3PG)
Ques-Mam you said that 6 times Calvin cycle occur for the synthesis of 1 molecule of glucose but glucose is 6 carbon compound it must be synthesized in 2 carbon cycles because 1 mol of PGAL are formed during in one complete C3 Cycle and two PGAL are formed in 2 C3 cycle which means 1 molucle of glucose
I really like your teaching style. I have seen all your parts of photosynthesis chapter. U teach it really nice. And all the videos of yours deserve the more views. Its really helpful
after listening to all classes based on photosynthesis I thought I ll never understand this chapter...but now I am getting more marks only in these chapter based tests Thankyou mam for your help
She is a very good teacher. Fluent English, no details missing, every concept explained and revised many times. Very helpful. But this video was a LITTLE worse as compared to the other videos of ma'am, because of a few reasons like RuBp was misspelled and mispronounced throughout the video. Just wanted to correct you ma'am. It's 'Ribulose Bisphosphate' instead of 'Rubilose Biphosphate'. Also RuBisCO is 'Ribulose Bisphosphate Carboxylase Oxygenase' instead of 'Rubilose Carboxylase Oxygenase'. Also, it would have been way better if you had explained the Calvin cycle, the way it actually happens in plants, and not the way we would understand better. [By combining only one molecule of CO² with RuBp, you could have run the cycle thrice till the formation of 6 molecules of 3-PGAL and then finally recovered 1 RuBp from 5 of them.] >>> This could have been repeated twice to form the one molecule of glucose, at last. In this way, the tracking of no. of carbon in each compound and the calculation of no. of ATP & NADHP required for the synthesis of one molecule of glucose would have both been easier. Not pointing out mistakes, but just suggesting better method of explanation. Still liked the video. The video was awesome, overall. And thank you.
Mam I am watching ur videos since from 2 years ur way of teaching is out standing Mam but in this lecture I am confused about no of carbons and molecules
Mam you are the best...and the best thing about your teaching is not what's happening buts its more onto..why /how/for what/ that is happening...which is very rear in most of the teachers
Learning from your lectures makes the entire process of photosynthesis more logical and intuitive to me .....thank you so much Mam....all your videos are really helpful!
mam please make videos on neural control and coordination ur videos are simply super awesome hats off you india needs teachers like u keep making videos on all possible chapters on biology of cbse class 11 and 12 waiting for ur videos thank you and now i am confident of answering questions from chapters that was taught by u .no words to express my feeling
u are too awesome!! i used to hate this photosynthesis topic but now just because of your amaing explaination i am loving it thankyou so much for provind this million dollor worth tutorials keep up this amazing work, you deserve billion views and subcribers may god reward you the best for this thankyou
Mam, a nice explanation given by you But please correct the full form written by you...of RUBISCO It is actually......"ribulose bisphosphate carboxylase" oxygenase

When RuBP +CO2 ››››› PGA( which is mono phosphate) synthesis is take place n plz tell me where does one phosphate go........... Plz clear my confusion.............
No, it's not passed into lumen. See, RuBP is a 5C compound and it combines with 1C CO2, in total it gets 6 Carbons. PGA is a 3C compound as you know. Actually, 2 molecules of pga are produced with one phosphate attaching to each of the PGA molecules. (The two phosphates coming from RuBP get distributed).
RuBp is 5C compound Total 6 RuBP So 30C and 6Co2 so +6C So total 36C converts to 6 molecules of 6C unstable compound And again converts to 12 molecule sof 3 PGA
Very super excellent explanation. But I have one more doubt, during photosynthesis 12 molecules of H20 utilised , 6 molecules of H20 released. In which stage water is released. Please explain madam.
0:31 This reaction is not light independent. It is indirectly dependent on light as it depends on the products of light reaction to occur. And so as soon as sunlight is removed, the light reaction stops and hence after sometime the biosynthetic stage or dark reaction stops. Hence, it cannot occur in the absence of sunlight
What an explanation !!,Simply superb I was being explained this concept a couple of times in college but never understood it satisfactorily Thanks a lot mam
18:39 mam you said there are 6 calvin cycle for the synthesis of 1 glucose molecule but actually there are 3 calvin cycles for the production of 1 glucose molecule mentioned somewhere so kindly clear? Anyone please?
Mam this vedio is very much helpful for me. But I think there should be a correction, i.e the full form of RuBisCO is "Ribulose Bisphosphate Carboxylase Oxygenase".

Ma'am where does c3 cycle takes place in choroplasts......... Is it stroma and if it occur in stroma then why cant it take place in c4 plant granal stroma as u told in ur next video..... Plz clarify??
You no what it doesn't matter at all she is master in this subject she knows everything and you are pointing out something which is not a mistake just a pronunciation that she is doing it different that's all
Imagine a weekend in which you were thinking to take rest after a busy week but then your teachers say to watch these videos and send the notes by evening? 😥 😥 😥 😥 😥 😥 WORST EXPERIENCE EVER😥😢
One of the best biology tutorial... Thankyou so much ma'am for providing such a standard lectures without any cost....your lectures are so much beneficial for us... 🙏🙏🙏🙏🙏
