Question

Which series lists the structural components of the light-dependent reactions in order, from smallest to largest?

1) chlorophyll ® thylakoid ® photosystem i ® photosystem ii
2) chloroplast ® photosystem ii ® photosystem i ® thylakoid
3) chlorophyll ® thylakoid ® chloroplast
4) chloroplast ® chlorophyll® thylakoid

Answer 1

The correct series that lists the structural components of the light-dependent reactions in order, from smallest to largest, is: Chlorophyll ® Thylakoid ® Photosystem II ® Photosystem I.

Step-by-step explanation:

The correct series that lists the structural components of the light-dependent reactions in order, from smallest to largest, is:

1. Chlorophyll ® Thylakoid ® Photosystem II ® Photosystem I

The light-dependent reactions in photosynthesis begin with chlorophyll, which is a pigment that absorbs light energy. The light energy is then transferred to the thylakoids, which are membrane structures found in chloroplasts.

The photosystems, specifically Photosystem II and Photosystem I, are complexes of pigments that capture solar energy and are embedded in the thylakoid membranes. Therefore, the correct order of the structural components is chlorophyll, thylakoid, Photosystem II, and Photosystem I.
