How many electron transport chains are there in photosynthesis?

Biology
1 answer:
Elena L [17]4 years ago
4 0
There are two electron transfer chains in photosynthesis. Both the two chains (Photosytem I and Photosystem II) are utilized to split water to get electrons. Electron transport helps establish a proton gradient that powers ATP production and also stores energy in reduced coenzyme NADPH. This energy is used to power the Calvin Cycle to produce sugar and other carbohydrates.

AVprozaik [17]
No; while a cell can use passive transport to bring in water, it must use energy to bring in larger particles. There also may not be enough of a difference in concentration of particles for diffusion to occur.
