Question

Which is an important difference between light-dependent (L-D) and light-independent (L-IND) reactions in photosynthesis?


A.The L-D reactions need CO2 and light energy, and the L-IND reactions needs water and O2.
B.The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH, and CO2.
C.The L-D reactions can only occur during daylight, and the L-IND reactions can only occur during the night.
D.The L-D reactions need water and CO2, and the L-IND reactions need CO2 and light.

Answer 1

Answer:

In the light-dependent reactions, energy from sunlight is absorbed by chlorophyll and that energy is converted into stored chemical energy. In the light-independent reactions, the chemical energy harvested during the light-dependent reactions drives the assembly of sugar molecules from carbon dioxide.

Answer 2

Answer:

Reactions of the Calvin cycle

Reactions of the Calvin cycleThe Calvin cycle reactions can be divided into three main stages: carbon fixation, reduction, and regeneration of the starting molecule. ... In the second stage, six ATP and six NADPH are used to convert the six 3-PGA molecules into six molecules of a three-carbon sugar (G3P). Reactions of the Calvin cycle
