What is the significance of the electron transport chain in photosynthesis?
Correct Answer: Electron transport chain ka kaam ATP aur NADPH banana hai.
- Step 1: Understand that photosynthesis occurs in plants and involves converting light energy into chemical energy.
- Step 2: Know that the electron transport chain is a series of proteins located in the thylakoid membranes of chloroplasts.
- Step 3: Realize that when light hits chlorophyll, it excites electrons, which then move through the electron transport chain.
- Step 4: As electrons move through the chain, they release energy.
- Step 5: This energy is used to pump hydrogen ions into the thylakoid space, creating a gradient.
- Step 6: The hydrogen ions flow back out through a protein called ATP synthase, generating ATP.
- Step 7: Additionally, the electrons help convert NADP+ into NADPH.
- Step 8: Both ATP and NADPH are crucial for the Calvin cycle, where carbon dioxide is converted into glucose.
