Give differences and similarities between the photosynthesis and aerobic respiration.
Give differences and similarities between the photosynthesis and aerobic respiration.
Similarities
- Both are energy converting processes.
- Both require mechanisms for exchange of carbon dioxide and oxygen.
- Both processes have a reaction pathway in which ATP is formed i.e. photo phosphorylation and oxidation phosphorylation in photosynthesis and respiration respectively.
- Bother processes involve enzyme-controlled reactions.
- Both require special organelles in eukaryotes, chloroplasts for photosynthesis and mitochondria for respiration.
- Both processes are affected by temperature.
Differences
| Aerobic respiration | Photosynthesis |
| A catabolic process (involves breakdown of carbohydrates into simple of sugar) inorganic compounds. | An anabolic process which results in synthesis of carbohydrate molecules from simple inorganic compounds. |
| Energy is incorporated into ATP for immediate use | Energy is accumulated and stored in carbohydrates |
| Oxygen is used up | Oxygen is released |
| Carbon dioxide and water are released | Carbon dioxide and water are used up |
| Process occurs in decrease in dry mass | Results in increase in dry mass |
| Process occurs in mitochondria in eukaryotes | Process occurs in chloroplast in eukaryotes |
| Takes place continuously throughout life and is independent of chlorophyll and light | Occurs only in cells possessing chlorophyll and only in the presence of light. |
