Question

Why the teeny tiny pigments packets are important ? Explain in a full paragraph.

This question is based off of the process of photosynthesis.

The teeny tiny pigment packets are referred to thylakoids, so why are they important.

Answer 1

Thylakoids are important because thylakoids are the site of the light dependent reactions of photosynthesis.The thylakoids themselves contain the chlorophyll, but the thylakoid membrane is where the light reactions take place.These reactions include light driven water oxidation and oxygen evolution, the pumping of protons across the thylakoid membranes coupled with the electron transport chain of the Photosystems and cytochrome complex and ATP synthesis by the ATP synthatase utilising the generated proton gradient.A major function of the thylakoid membrane and its integrated photosystems is the establishment of the chemiosmotic potential. The carriers of the electron transport chain use some of the electron's energy to actively transport protons from the stroma to the lumen. During photosynthesis the lumen becomes acidic. This represents a 10,000 fold concentration gradient for protons across the thylakoid membrane.
