Question

I wonder that if the mitochondria are the bacteria going into ancestral human cells,that means human cells before that didn't have mitochondria,which source did they use to produce energy then? I don't think only anaerobic process could produce enough energy for human

Answer 1

well when the first time evolve the life was in anaerobic condition and if we talk about ur question dat time the energy was anaerobic itself becoz as the evironment become aerobic life organism died immediately but some of them survive becoz of variation and it was seen that mitochndria is present in them

Answer 2

means with the evolution change also come in exisistence and we knw mitochondria itself evolve from bacterai

Answer 3

i don't understand why life organism would have died immediately if the environment had become aerobic?
and you mean our ancestors like Luci or maybe before that used only anaerobic process for survival?

Answer 4

luci ? well i m telling u from begining if u interested i ll tell u how the life evolved as a story but in hort the organinsm which was formed were habitual of aerobic condition but sudden change a anaerobic condition they are unable to survive

Answer 5

and u knw virus is formed earlier in the history.. at the time of evolution when the condition were anaerobic..

Answer 6

alright alright! but what was the source of human energy before the mitochondria went into human cells??

Answer 7

welll u knw how human evolve retriceit dosent appear originally due to ssevearl mutation human formed and if we go back to the history there might be some stage at which mitochondria also formed and was present in cell i guess

Answer 8

have u read or knw how evolution occur i mean on earth how very thing came in exisistence?

Answer 9

if u are interested i ll tell u :)

Answer 10

I am really interested in human evolution,in fact,all evolution of lives.I have studied about human evolution but it was not that detailed.
I am ready to study from you now :P

Answer 11

glad and i make u sure u ll not get bored :) so now the movie starts :P

Answer 12

at the begining no one know how earth formed so one theory was given name big bang theory

Answer 13

in big bang theory it was proved that particles in the universe get collashed in a loagrge amount and formed a flat disc called "nebula" and due to thiss explosion one hot nebula formed which is geting hotter and hotter nowadays we called it sun

Answer 14

u knw u have read some news regarding abu the death of earth 2012 on 31 december?

Answer 15

I have heard of it but I don't believe it will come true.it's just something written in mayan calendar if I don't get it wrong. but why?

Answer 16

well it is true not i ll say surely but it is so there is a experiment going underground like big bang theory but not copleted yet in newzeland (geneva)

Answer 17

you mean the earth is near to the end now?

Answer 18

with the help of machine LHC (large hadron colloider ) and u knw in xperiment many things are observed it was happening same like earth evolved and many new atom and particles are also observed in the experiment which are not known to us :)

Answer 19

no i nvr said that its the xtra info i given u for ur knowledge :P anyways leave it :) but from my opinion there will be large destruction only and besst sspecies will be selected by the nature called natural selection

Answer 20

anywas coming back to our story :P

Answer 21

now on nebula solid part is called lithosphere and gaseous part is called atmosphere

Answer 22

now time goes on and when temp of earth cools down to 100'C water formed in it

Answer 23

@guykubpom y u lagging :O if u nt interested i m leaving :/ u can read this stuff from net too :/

Answer 35

I would assume that Eukaryotic cells produced energy the same way bacteria do before they were colonised by the bacteria that became mitochondria. And no, I don't know the details. I just know it's possible to produce energy without mitochondria because bacteria don't have them, and they do just fine.

In any case, this all happened a LONG time ago, so it's not particularly useful to talk about "ancestral human cells". Rather, think of them as the simple cells that were the ancestors of ALL EUKARYOTES -- plants, animals, fungi, and protists. And, of course, they probably didn't need quite as much energy in those days. They were single-celled organisms, after all.
