What replaces the electrons that are lost by energized photosystem I?

What replaces the electrons that are lost by energized photosystem I?

The electron arrives at photosystem I and joins the P700 special pair of chlorophylls in the reaction center. The special pair’s missing electron is replaced by a new electron from PSII (arriving via the electron transport chain). NADPH formation.

What supplies the electrons that are lost in photosystem 1?

What happens to the electrons that are lost by photosystem I? Electrons in photosystem II are carried along an electron transport chain and replace electrons lost by photosystem I. Electrons from photosystem I are carried along a different electron transport chain and drive the synthesis of NADPH.

What is the final product of photosystem 1?

ATP is the product of photosystem I.

What is the main role of photosystem 2?

Photosystem II (PSII) is a multi-component pigment-protein complex that is responsible for water splitting, oxygen evolution, and plastoquinone reduction.

What wavelength is best absorbed by chlorophyll?

In the case of chlorophyll a the maximal absorption in the red region is at 642 nm and in the blue region at 372 nm; for chlorophyll b the values are 626 nm and 392 nm, respectively.

Which wavelengths of light are best absorbed by chlorophyll?

As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.

Which human body part is the epidermis of a leaf similar to?

skin

Why are plant leaves green quizlet?

Leaves are green because of a pigment known as chlorophyll. The chlorophyll masks the colors of any other pigments in the leaf cells. In the autumn, chlorophyll breaks down revealing other colors present in the leaf. You just studied 15 terms!
