In the process of photosynthesis, in autotrophs convert solar energy into chemical energy and store this 'food' for later use. The reaction for photosynthesis is: 6CO2(g) + 6H2O(l) + energy --> C6H12O6(s) + O2(g). In the process of , mitochondria in the cells of plants, animals and other multicellular organisms break down 'food' molecules to generate molecules of . This is the source of energy for all cellular functions. The reaction for cellular respiration is:

ATP
chemosynthesis
chloroplasts
cellular respiration
NADPH and FADH2
C6H1206(s) + 02(g) -- CO2(g) + 6H20(I) + energy

1. Chloroplast

2. cellular respiration

3. ATP

4. C6H1206(s) + 02(g) -- CO2(g) + 6H20(I) + energy

Explanation:

This question is describing the processes of photosynthesis and cellular respiration. Photosynthesis occurs in the CHLOROPLAST, which is responsible for the conversion of solar energy (from sun) into chemical energy (in glucose). The general photosynthetic reaction is:

6CO2(g) + 6H2O(l) + energy → C6H12O6(s) + O2(g)

Contrarily, the process of cellular respiration occurs in the MITOCHONDRIA. Cellular respiration involves the breaking down of food molecules to synthesize ATP (energy) for use during biochemical reactions. The general chemical reaction is as follows:

C6H1206(s) + 02(g) → CO2(g) + 6H20(I) + energy

b is the correct answer
