Question

Select any net outputs of light-dependent reactions:

a.) glucose
b.) thylakoid
c.) NADPH
d.) ADP
e.) ATP
f.) O2
g.) NADP+

Answer 1

The correct net outputs of the light-dependent reactions are ATP, NADPH, and O2. ATP and NADPH are energy carriers used in the Calvin cycle to produce glucose, while O2 is released as a byproduct into the atmosphere.

Step-by-step explanation:

The light-dependent reactions of photosynthesis occur within the thylakoids of chloroplasts and have specific net outputs that are essential for the subsequent light-independent reactions. The outputs of the light-dependent reactions include ATP and NADPH, which are forms of chemical energy, and O2 (oxygen) as a byproduct of water molecule splitting. Contrary to options A (glucose), B (thylakoid), D (ADP), and G (NADP+), which are either inputs or components of the photosynthetic apparatus rather than outputs, the correct choices are C (NADPH), E (ATP), and F (O2).

These energy carriers, ATP and NADPH, are utilized in the Calvin cycle (also known as the light-independent or 'dark' reactions). During the Calvin cycle, they provide the necessary energy and electrons for the production of glucose from carbon dioxide. The oxygen produced is released into the atmosphere as a vital gas for the respiration of most living organisms.
