Hint: Anabolism involves the conversion of the small molecules into the large molecules. Whereas the catabolism is the process in which the larger complex molecules break down to the smaller simpler molecules. Since the process of catabolism involves destruction reactions of breaking complex molecules, it is also known as the destructive metabolism.
Complete answer:
It is the process in which the plants prepare their own food. In this process, the carbon dioxide and the water is combined to produce the sugar molecules and the oxygen. This takes place with the help of sunlight and chlorophyll. It is the anabolism process.
(B) Respiration:
Respiration is the process which is concerned with the conversion of the complex organic compounds into the smaller molecules by the oxidation with the release of energy.
(C) Glycogenesis:
The glucose that is obtained from the food cannot be stored as much. Thus, it must be converted into the glycogen by adding the glucose to the chain of glycogen. This process is called glycogenesis.
From the above explanation it is clear that photosynthesis and the glycogenesis process are anabolism and the respiration process is catabolism reactions.
Hence, the correct answer is Option (B)
Note: The catabolism reactions are totally opposite to the anabolism reaction. The example of anabolism reaction is gluconeogenesis in which the glycogen is converted into glycogen. The example for catabolism is glycolysis in which the glycogen is converted into glucose.
