All right, so for this problem, we are looking at different parts of the process known as photosynthesis.
00:08
Photo referring to light, think about a photon, and synthesis meaning to create.
00:14
So we're using light to create sugars in this aspect.
00:22
So we're turning solar energy into chemical energy.
00:30
So one of the first steps we know is that let's draw this in green.
00:35
Or black, let's do, is that light, which is the solar energy, will come down and it will hit photosystem 2, which is one of the chlorophyll molecules in the reactions that are complex.
00:51
So it's a photo system 2.
00:55
Then we have lights here.
00:58
And this will cause a loss of electrons.
01:05
And these will move on and have different functions later.
01:09
But we need to know how are these electrons replaced in the photo system? so something else occurs in photosynthesis in the light phase around this period of time.
01:21
We have a molecule of h2o, which if we remember the chemical reaction, sorry, sorry for that stuttering there.
01:34
The chemical reaction for photosynthesis, there are reactants and products...
