Question
In sunlit leaves of a plant, the thylakoid lumen has a comparatively high concentration of:
- Electrons
- Protons
- Rubisco
- Chlorophyll
Solution
The thylakoid lumen in sunlit leaves of a plant has a comparatively high concentration of Protons.
Here's the step by step process:
-
Photosynthesis begins in the thylakoid lumen of the chloroplasts in plant cells.
-
When sunlight hits the chlorophyll in the thylakoid membranes, it excites electrons and boosts them to a higher energy level.
-
These high-energy electrons are then passed along a series of proteins (the electron transport chain) embedded in the thylakoid membrane.
-
As the electrons move along the chain, their energy is used to pump protons (H+ ions) from the stroma of the chloroplast into the thylakoid lumen.
-
This creates a high concentration of protons within the thylakoid lumen, setting up a proton gradient.
-
The protons then flow back down their concentration gradient through a protein called ATP synthase, driving the production of ATP, the energy currency of the cell.
-
This process is known as photophosph
