Question

Choose “light” or “dark”: a)  Which reaction of photosynthesis changes the energy of the sun into chemical energy?  b) Which reaction of photosynthesis puts carbon dioxide into the form of carbohydrates?

Answer 1

The light-dependent reactions of photosynthesis convert sunlight into chemical energy, while the light-independent reactions, or Calvin cycle, convert carbon dioxide into carbohydrates.

Step-by-step explanation:

In photosynthesis, the conversion of sunlight into chemical energy occurs in the light-dependent reactions. Chlorophyll absorbs energy from sunlight and converts it into chemical energy with the help of water. This process releases oxygen as a byproduct. On the other hand, the light-independent reactions, also known as the Calvin cycle, use the chemical energy derived from the light-dependent reactions to convert carbon dioxide into carbohydrates.

Answer 2

a) Light reaction

b) Dark reaction.
