Question

the process that uses oxygen to break down glucose takes place in the

Answer 1

cytoplasm of cells

Answer 2

this is called glycolysis

Answer 3

then all this business happens:
The products of glycolysis the enter the Citric Acid cycle which is also in the cytoplasm. The electrons obtained from this process are carried in the form of NADH and FADH2 to the mitochondrial membrane where they go trough the respiratory chain of oxidative phosphorylation. As they go through, protons are pushed to outside of the membrane, creating a proton motive force. The protons then move back in through an enzyme called ATP syntase and make ATP, the cell's energy currency.

Answer 4

where does it take place in or at

Answer 5

Hai!!! @dexcole

Welcome to Open Study!!! *^o^*

as @PRAETORIAN.10 had stated, this process takes place within the cytoplasm of cells.


Bunnies wishes you the warmest welcome to the Open Study family, and the best of luck with your future studies!! *^o^*

Answer 8

Glycolysis results into the breakdown of glucose into pyruvate, now this pyruvate is converted into acetyl Co-A, which then enters into TCA or CAA or Kreb's cycle. Here it is oxidised to obtain energy. This process occurs in the mitochondria and not in the cytoplasm

Answer 10

@Abhisar i don't know this T_T

Answer 11

ohkay @Somy T_T

watch the vid

Answer 13

lol this video is your full answer @dexcole

Answer 14

No its not...... :D

Answer 15

=_= @Abhisar well you gave the beginning answer :P

Answer 16

It tells only upto glycolysis...oxidation occurs in the next step i.e kreb's cycle

Answer 17

@Abhisar well i don't know anything about this lol but well i hope this helps to clear up the first part then :D

Answer 18

aso there is no info about the location in the video :(

Answer 19

location i think is mitochondria

Answer 20

Anyways....thankyou so much for responding to my call :)

Answer 21

yes that's what i know..MITOCHONDRIA...but i needed a confirmation...since i am going against the above discussion :)

Answer 23

i think this one is your full answer @Abhisar

Answer 24

Thanks a TON !!!
@Somy ....u r my life saver !!

Answer 25

lol i just focused on what you said and searched it, nothing much @Abhisar google is your lifesaver :D

Answer 26

LOL...no thats not exactly true...u bothered to do that....!!!!
So u r my life saver

Answer 27

lmao okay let it be like that :D thnx @Abhisar :*

Answer 28

yeah u bttr dont mess wid me @Somy :D

Answer 29

owkaaay @Abhisar lol

Answer 30

I'll say Mitochondrion too but m not 100 % sure
@ParthKohli @deepika.comet

Answer 31

@Destinymasha

Answer 32

The process of GLYCOLYSIS occurs in the cytoplasm of cells and then the result i.e., PYRUVIC ACID formed from glycolysis enter the KREB'S CYCLE for futher process.

IF NEEDED ANY FURTHER CLARIFICATION I CAN ALSO JUSTIFY MY ANSWER CLEARLY..... if needed...

Answer 33

aamm..but i think glycolysis dont need oxygen !

Answer 34

ya glcolysis dont need oxygen but krebs cycle dont start with glucose...!!!!

Answer 35

Krebs cycle is the continuation of glycolysis it can never occur without glycolysis and is the process which is aerobic in nature and it happens in mitochondria. Question asks the location of such process so i thought it will be mito

Answer 36

may be i am wrong..but this is what i think

Answer 37

also glucose is broken down into lactic acid in anaerobic conditions, this takes place in cytoplasm. Glycolysis is a common pathway occuring both in aerobic and anaerobic respiration

Answer 38

afterall we all know mitochondria's purpose

Answer 39

Pls dont take it offending...i am just tryng to discuss things :)
@deepika.comet

Answer 40

ya sure i was on the other work didnt see this im sorry

Answer 41

ya what all you told is correct actually the answer but be of two phases oxidation of glucose occurs only in the presence of oxygen and the two phases would be Glycolysis and Krebs cycle where glycolysis occurs in the cytoplasm of the cells and the krebs cylce occurs in the mitochondria..

Mitochondria is considered as the site of respiration hence it requires oxygen therefore this part is lacking in anaerobic bacteria as they dont have mitochondria and no respiration takes with which it doesnt require any oxygen...

Answer 42

so the final answer is

Oxidation of glucose requires two phases glysolysis and krebs cycle where glycolysis occurs in cytoplasm and krebs cycle occurs in the mitochondria in the presence of oxygen...

Krebs cycle is absent in the anaerobic bacteria because they dont have mitochondria and dont require oxygen..

@IamStark @abhisar @Somy

Answer 43

u r absltly crrct @deepika.comet and some how the question demands about aerobic respiration and it can only take place in mitochondria as u just said :)

Answer 44

If we talk about eukaryotes

Answer 45

thank you and it must be asked how many phases, which places and what organisms participate in this..............

Answer 46

in prokaryotes they lack mitochondria so they dont require oxygen and the glucose gets converted to lactic acid or ethyl alcohol..

Answer 47

But i think it will be cyto if we consider it as an aerobic bacteria

Answer 48

@deepika.comet but there are some aerobic bacteria

Answer 49

ya there are but mostly we see the process of glucose oxidation only in the organisms which have mitochondria and who require oxygen regardless it is and eukaryote or prokaryote

Answer 50

but commonly told wording is eukaryotes have aerobic respiration and prokaryotes have anaerobic respiration..

Answer 51

u r ryt @deepika.comet and i will like to conclude this discussion as following
both types of respirations i.e aerobic and anaerobic occurs in both prokaryotes and eukaryotes. In both the methods glycolysis is must and common which occurs in cytoplasm and as u said it does not require oxygen. Now the next step is the entry of pyruvate (final product of Glycolysis) as Acetyl Co-A into the mitochondria in eukaryotes. Here kreb's cycle takes place and oxygen is used to extract energy. If we talk about prokaryotes the same kreb's cycle occurs in MESOSOMES (folded invaginations of plasma membrane). So the answer will be Mitochondria. Since its generally spoken as oxidation of glucose

Answer 52

Someone called? :D

Answer 53

too late lol @KL-RC

Answer 54

Oops
haha

Answer 55

@shrutipande9

Answer 56

yes @abhisar?

Answer 57

i want to know ur opinion on this question @shrutipande9

Answer 58

when the question specifically says use of oxygen then it is mitochondria. glycolysis takes place in cytoplasm but it does not involve oxygen...

Answer 59

Thankyou @shrutipande9 !

Answer 60

ur welcome..:D
