Oh, Hello, you're listening to the Science of Everything podcast, episode 101,

photosynthesis, part one.

And I'm your host, James Fodor.

So, in this episode, we are going to discuss photosynthesis, as the title suggests.

In particular, I'm going to talk about the main structures of the plant cell that support

photosynthesis, so the phylochoid membrane

and the granum which exists inside the chloroplast. I'm going to talk about the overall

chemical reactions that occur as part of photosynthesis, so the reaction of carbon dioxide and water

to produce sugar and oxygen, and how that fits into plant metabolism.

But then we're going to go through and talk in some detail about the different biological complexes and protein complexes that support photosynthesis.

So Ferdosystem 2, the cytochrome complex, Foto System 1, NADP reductase, the ATP synthase,

and the various complexes and molecules that connect them together.

So we'll go through at a fairly fine grain of analysis through the process of light absorption

by chlorophyll and the other pigments and then how the electrons move through the different complexes in the in the in the chloropath membrane.

Particularly we're going to focus on electron flow and how the energy is gradually extracted from the electrons to produce NADP, NADPH, and ATP,

which is the main sort of energy products of photosynthesis as a process.

So there's quite a lot to get through, and it's difficult to describe a lot of this

without using diagrams or visualizations.

So as usual, I will do my best.

Recommended pre-listing for this podcast is a bit wide-ranging because we're going to talk about

quite a few issues here. Episode 75 on cellular respiration is the single most relevant episode,

because that's sort of the flip side to this. Cellular respiration is basically the process of using sugar and oxygen to produce energy,
