Glycolysis Step wise | Cellular respiration

- The term cellular respiration is an oxidation-reduction process in which organic food is broken-down inside the cell and energy is released, Hence it is the form of catabolic process.
Cellular respiration includes both aerobic and anaerobic processes.
The harvesting of energy from glucose by cellular respiration is
a cumulative function of three metabolic stages.
Glycolysis, PYRUVATE OXIDATION and the CITRIC ACID CYCLE or Kreb's Cycle, and Electron Transport Chain ( ETC).
Glycolysis, which occurs in the cytosol, begins the degradation process by breaking glucose into two molecules of a compound called
pyruvate.
The word glycolysis means “sugar splitting,” and that is exactly what happens during this pathway. Glucose, a sixcarbon sugar, is split into two three-carbon sugars. These smaller sugars are then oxidized and their remaining atoms rearranged to form two molecules of pyruvate. (Pyruvate is
the ionized form of pyruvic acid.)
glycolysis can be divided into two phases: the energy investment phase or preparatory phase and the energy payoff phase or Oxidative phase. During the energy investment phase, the cell actually spends ATP. This investment is repaid with interest during the energy payoff phase, when ATP is produced
by substrate-level phosphorylation and NAD+ is reduced to NADH by electrons released from the oxidation of glucose.
The net energy yield from glycolysis, per glucose molecule,
is 2 ATP plus 2 NADH.

Lots of thumbs up to those who make such very helpful educational videos..👍
You are the best teacher in my life without seeing but only too much learnt from you
❤
Bhai aap jo yeh point figure banake explain karte ho sach me poora concept clear ho jata hai thank you sir ❤❤
Sir apka hi lecture mujhe bhot ache se samjh me ata hai thanks for wonderful teaching 👌👌👌🙏🙏🙏🙏love you from India 🇮🇳
Hmm
your and Ali academy biology lectures channels both of you two saved my biology thank yuh
AMAZING teaching...came across this video..crisp n to the point ..lots of love from india
Online class can alsobe done like this....keep it up sir ❤❤
Allah Pak Aap ko sehat Wali Lambi Zindagi aata Farmayen Ameen
Sir Meri request ha ka aap do minutes side ho jawo hum screenshot ker la our sir pick clear hone chai
Chhl 😂
😂
Start mai hota hain
😂😂
Mashallah mashallah mashallah sir you r the best
The way u covers each and every point sir ,,,it lefts me speechless seriously whenever a question pops in my mind u catch it ....🔥🔥🔥
Your teaching method is really awesome and impressive........thank you so much 😍
The best short and concept clearing leactures❤❤
Sir you are only one to whom I listen on this youtube ...stay blessed
❤
Nice brother ....... Thanks for you kafe acha understand karvate h app 👍
You are really awesome teacher after khan sir
Thank you so much sir for this great lecture ❤️❤️. May God bless you
Video is really helpful 🥰 thanku
It's Very Helpful Masha Allah
Jazakallah Sir
Mugha ya unit sab sa zaida difficult lagta tha aur isa kabi bi sahi sa na parh saki par sir ap ka lectures sa ya unit ab boath easy ho gaya hy
Thanks
Respiration has four process
Glycolysis
Pyruvic acid oxidation
Krebs cycle
Respiratory chain
The way of teaching this man is outstanding ❤️
ALWAYS SAVING MY BIOCHEMISTRY EZAM THESE VIDOES ARE THE BESTTT
Dear sir iam vijay from hyderabad india i follow your lectures sir its so simple and easy to understand the concept your explanation is concept based, iam really thankful to you sir may i know where r u from sir
clapping very well sir my topic is clear now Thankyou so much sir you are doing very well work and your teaching style is very good
Your videos are really helpful sir..Thank you so much 🙏🏻😃
Excellent 👍 teaching skills sir I never seen ever
Sir thanku so much .huge respect💖 Ur teaching way is impressive as well as very understanding .👍

the video i was finding for two days❤👍❤
Love from india,superb explanation sir
Outstanding lecture 👌
Simply awesome way of delivering a lecture!
Best teacher
Very clear way of teaching❤
Plzz suggest me the best channel of biophysics concept
Love from India 🇮🇳
I invite you to accept Islam
Please also tell which chapter are you giving lecture on
well done i have no words to define your talented and interesting lectures👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏👏
i am from india and i like your way of explaining
best teacher👏🏻👏🏻👏🏻very helpfull ❤
Thank you so much sir ☺️☺️❣️
Amazing teacher ❤❤😊😊
Amazing lecture
Sir g kindly glycogenolysis .glycogenesis and gluconeogenesis per videos bna dain
ur video is so helpful for my exams thx
Best Teacher of biology
God bless u tchr u r the best
Sir please 2nd year ke topics upload kre
King of biology ❤❤❤i watct your lectures daily .thinks for uploading such amazing lectures
Thanks for amazing and wonderful lecture 😊😊🥰🥰🤩
Outstanding lectures ❤
Sir please make lectures of metobism of carbohydrates protein lipids and nuclic acid
Well done 👏
Good work keep it up❤
Bhai u r Nice one and u r lecture is easy to understand 💖
Thank yoh so much sir ♥️ u ate outstanding sir ♥️♥️ God bless you ❤️❤️❤️
Sir kon si enzyme ki madat si convert hoti hi enzymes name batai
in case of aerobic respiration why glycolysis occur in cytoplasm not in mitochondria
sir g ya ADP ka sat jo pasphate attach howa or 2atp energy generate hwa .is ma ADP kha sa aya.
plz answer
Best explanation 💯
You are best teacher
Apka hr lecture smj aaa jaata haa
I really like your leacture dear sir g
9:02 Sir Glycolysis k pehlay phase mai jo preparatory phase hota hai us mai glucose 2PGAL mai nhi G3P mai change hota hai. ( Kya PGAL aur G3P same hai??)
Yes.
phosphoglyceraldehyde (PGAL) glyceraldehyde 3-phosphate.(G3P)
I only follow you you are best techer
Wonderful video.❤
Sir you not mentioned the enzyme?
Oxidative phase main PGAL molecule ke saat ye dusra phosphate kaha he attached hogaya
Best explanation ❤
Thanks sir it was very nice lecture ❤
Your lecture is very helpful Sir
Sir step no 8 missing lag rha hy or bisphospho glyceraldehyde Hotaa hy ya bisphosphosphoglycerte plzz reply?
Hamary pass do compounds hai aik PGA that is phosphoglycerate and doosra PGAL phosphoglyceraldehyde
Dono may difference ye hai k PGA hamary pass 3C compound hai Jo reduce hojata hai to phosphoglyceraldehyde PGAL
I hope my answer can help you

Sir sab kuch bhatreen samajh aaa gya but ik cheez samajh nahi aai
Question
1. glucose + Atp
2. glucose +phosphate at 6 (C)
3.fructos 6 phosphate.
4.fructos-6-p + ATP
5.fructos-1,6-di-phosphate.
6.2(glyceraldehyde+3-p)
Yaha taq sab tike hai but
7.2(1,3-di-p-phosphoglycerate.
Ya do phosphate kaha sai aai yaha to sirf hydrolysis hi hui hai. Koi atp nahi laga to ya do phosphate kaha sai aai
Walaikum assalm
When PGAL oxidized and NADP is reduced it forms a refox reaction. As a result energy is relased which is used to join the phosphate present in the cystol with PGAL to form (1-3 bisphosphoglyceraldehyde). I think so that is the procedure 😊
@@mr.cricketeditz2.09
Yes you are right 👍
Boht umdah samjhaya apne ek sawal tha mera
Best teacher ❤
Can u upload video about New text sindh book
Very helpful sir keep it up💕💕
Why it is called substrate level of phosphorylation😊
Thanks for your lectures sir😊
Hats off to you sir
It was really helpful video ❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤🎉🎉🎉
Sir g best teacher
Jazakallah Sir
@14:10 where does P come from?
Correction please:
Fructose-1-6bisphosphate is broken down into DHAP and G3P...not PGAL
Wow good Methodist
Wa alaikum slam nice lecture
Thank you very much sir
Sir can you explain gluconeogenesis plzz!
yes
Sir gluconeogenesis pr bi lecture upload or dy
I can't understand when Furctose convert into Bi phosphate
Great sir
Sir please loud bola karen aap bhot acha samjhate hai liken voice thori slow hai sorry but please
Bro I have my bio exam in next 45min and here I am 🥲 after coming here I realised I have whole bunch of things which I have not read 🙃 good luck to me 😂
Result Ka Kia bana
@@ArhamAlterpass ho gyi jese tese karke 😂
😂😂😂😂
Nice lecture sir
Sir transport across mitochondria & ER ka video provide kijiye
Sir agar 2 ATP use bhi ho rhy or 2 ATP gain b ho rhy to phir iska faida kya hy wahi bat hui
Ye Jo 2 ATP use hoe Hai ye process ko start Karta Hai awr last mai phir 36 ATP generate hoty Hai.
Awr Agar sirf glycolysis Ki baat karty ho tu 4 ATP awr 2 NADH release hoty Hai jismy pehly sy 2 ATP use hoe Hai tu net gain taqiban 7 ATP banty hai
Sir Alluh ap ko ganat ul Fardus nasib kara
