00:00:00
ah today's topic photosynthesis
00:00:12
and
00:00:18
photosynthesis is a chemical process used by plants through which it produces chemical energy
00:00:25
from solar energy thanks to the energy of the sun plants convert the water from the soil
00:00:32
and the carbon dioxide found in the air in glucose imagines that it is a factory where
00:00:39
with these two ingredients it is going to create glucose that is being energy photosynthesis is
00:00:46
the most important chemical process on the planet since through this organic
00:00:52
substances are synthesized from solar energy in photosynthesis they participate All organisms
00:00:58
that have chlorophyll such as plants, algae and some bacteria, it is also very
00:01:04
important to note that through this process, plants produce their own food, which
00:01:10
makes them autotrophic organisms and this entire photosynthetic process is divided into two phases: the
00:01:17
light phase and the dark phase but today we are going to talk about the dark phase so it is that we begin
00:01:37
the 40s are the end of the second There is only one world war left and the participating and affected
00:01:43
countries were trying to recover, but while this was happening at the University of California,
00:01:48
research on radioactive isotopes of carbon 14 was beginning, so we are going
00:01:55
to receive a loud applause to Mr. Photosynthesis, to whom we are going to dedicate this
00:02:00
small video he is martín hot and thanks to him they ask us about the dark phase of
00:02:07
photosynthesis in the exams although they already had knowledge about photosynthesis, it was not
00:02:13
really known for sure the steps that carbon dioxide followed to transform or
00:02:19
convert them Glucose also wanted to know what a nobel prize in chemistry gave him and
00:02:25
of course the name of the calvin cycle which is also known as the calvin cycle
00:02:31
version because there is a certain benson or cycle of in the carbon fixation of photosynthesis
00:02:40
The calvin cycle consists of a series of biochemical processes and all of these are to be
00:02:46
carried out in the stroma of the chloroplasts so again I present to you the chloroplast
00:02:52
these are the linden with is where the light phase of photosynthesis occurs but this time
00:02:58
we are going to work in the stroma where the magic of the calvin cycle occurs three
00:03:03
important aspects will happen during the phase dark of photosynthesis the first is that it
00:03:10
is going to fix the carbon dioxide that exists in the environment to transform it into an
00:03:15
organic molecule called glucose the second is that it will use the molecules that we obtained
00:03:21
in the light phase so if not You have seen this video I leave it at the top so
00:03:27
that you can take a look at it and finally, although it is called the dark phase, it really does not need to
00:03:34
occur at night, in short, it is called the dark phase because it does not require sunlight
00:03:40
or of the photons this cycle is going to be divided into three stages stage 1 fixation stage 2
00:03:47
reduction and stage 3 regeneration before starting I want to introduce you to the triangle
00:03:53
called here gle e cerato I also introduce you to the pentagon that is called rigorous here and this
00:04:01
is the hexagon called ex osa I hope you have learned them rigorous literary ex osa rigorous literary
00:04:09
and ex osa very well with a lot of attention we are going to attract once again to the rigorous every
00:04:16
corner of each geometric figure represents a carbon molecule and they will always be numbered in
00:04:22
this order 1 2 3 4 and 5 you can also see it this way now if we add
00:04:32
a carbon it would become an ex osa but if it is sexes to divide it into two have two leaderships
00:04:40
now I will introduce a new molecule called phosphorus but when you see a whole
00:04:47
be called phosphate now if we bring together phosphate with writer and as phosphorus is in
00:04:55
carbon number 2 goes to receive the name of red literary 2 will offer all phosphate I hope you have understood me
00:05:05
this is a small review of carbon chemistry so that you can understand this cycle we are going
00:05:12
to suppose that now you not only have u n phosphate but now it has the 2 then since you have 2 it will
00:05:19
receive the name of my phosphate for example in the first one which is glee cerate now it would be gray it was
00:05:26
all and 3 phosphate and so on with all the others now I want to introduce you to adenine
00:05:36
but when it is inside a circle it will take the name of adenosine and if we add three
00:05:44
phosphates to this it will be called adenosine triphosphate or adenosine triphosphate better known as atp and
00:05:53
now if we remove a phosphate it will love bp and Finally, I want to present you with a record that is
00:06:02
this horrifying thing, but we are going to present it to you in this way. Actually, a record is an enzyme
00:06:09
and his job is like that of a policeman, since he has to look for bad co2 and remove the excellent
00:06:19
carbon from them. that now you have the necessary knowledge to accompany me
00:06:24
to see this sad story there was once in a very distant place called stroma a rigorous 5
00:06:33
phosphate that really did not accept himself did not care at all And nothing in order to get
00:06:39
what he wanted a quiet night he found the atp and without caring he snatched a phosphate
00:06:47
transforming it into an atp and being very very sad the revu los a 5 phosphate now had an
00:06:56
extra phosphate so he put it in the number 1 position turning it into a rigorous 15 and
00:07:04
phosphate now walks around showing off everything he owned until suddenly a bad co2 appeared
00:07:12
but that didn't matter because the police arrived immediately that's how Rubisco arrived and took a
00:07:20
coal from him and how is the good vibes and I thought that that carbon belonged to the rigorous one, he gave it to her
00:07:28
and with this she transformed into a beautiful and beautiful ex osa one six discs for you this ex osa
00:07:35
became arrogant and unstable presumed so they broke his mandarin into wedges people in
00:07:42
two parts becoming two leaders with a phosphate in the third position turning them
00:07:51
gray was all three phosphate these two leaders 3 phosphates were still half crafty and walking
00:08:00
they met 2 atp so it is that without caring again they stole a phosphate and these 2 atps
00:08:09
became 2nd in weight and they were also sad and the leaders now became
00:08:17
literary 13 and phosphate all this did not like the neighboring community called maps that come of
00:08:26
luminous photosynthesis, so they began to throw electrons and protons to these two
00:08:33
leaders, as they ran out of hydrogens, they had no choice but to change the name of their community
00:08:39
to the sea, on the other hand, the 1/3 phosphate leaders after the beating that They gave
00:08:48
each one a phosphate lost to this part it is called reduction the leaders three phosphates began
00:08:55
to be persecuted everywhere so they decided to change their name to isr aldehyde
00:09:02
3 phosphate this sounds like when your name is jose and now you want to be named pp the important thing
00:09:09
is that these 2 Law 2 Lawyers have decided to behave well and regenerate transforming into a rigorous
00:09:17
5 phosphate and as you will realize we return to the beginning p Orque to produce glucose, Calvin's
00:09:24
cycle needs to turn all that glucose 6 times the plants can transform it into
00:09:30
starch and use it as reserve energy and as we Mexicans say colorín
00:09:37
colorado that this story is over, do not forget to subscribe and give me a good gift bad
00:09:43
remember dream we make great because to the one who believes everything is possible
