Questions and Answers

What are the two light-dependent reactions involved in photosynthesis?

photosystem II (PSII) and photosystem I (PSI)

What is the by-product created in oxygenic photosynthesis?

oxygen (O2)

What is the main process by which plants acquire energy?

photosynthesis

How is ATP produced in non-cyclic photophosphorylation?

<p>Cytochrome b6f uses electrons from PSII and energy from PSI to pump protons from the stroma to the lumen, creating a proton gradient across the thylakoid membrane used by ATP synthase to form ATP</p> Signup and view all the answers

Why is cyclic photophosphorylation important?

<p>It is important to create ATP and maintain NADPH in the right proportion for the light-independent reactions.</p> Signup and view all the answers

Study Notes

Photosynthesis Process

Two light-dependent reactions involved in photosynthesis are: Light-Dependent Reactions and Calvin Cycle
By-product created in oxygenic photosynthesis is Oxygen

Energy Acquisition in Plants

Main process by which plants acquire energy is Photosynthesis

ATP Production

In non-cyclic photophosphorylation, ATP is produced through Electron Transport Chain, which generates a proton gradient that drives ATP synthesis
In non-cyclic photophosphorylation, ATP is produced in the Thylakoid Membrane

Importance of Cyclic Photophosphorylation

Cyclic photophosphorylation is important because it generates ATP only, without producing NADPH or Oxygen, which is essential for plants in low-light conditions or when CO2 is limited
