Answer:
PHOTOSYNTHESIS:
- Light energy is absorbed
- Glucose and oxygen are products
- Carbon dioxide and water are inputs
- Chemical energy is produced
CELLULAR RESPIRATION:
- Carbon dioxide and water are outputs
- Chemical energy is released
- Glucose and oxygen are inputs
- ATP, motion and heat energy are produced
Explanation:
- Photosynthesis is process by which autotrophic organisms synthesize their food (glucose) in the presence of sunlight. The process combines carbon dioxide (CO2) and water (H20) to produce glucose (C6H12O6) and oxygen (O2), by the energy derived from absorbing light. In the process, light energy is transformed to chemical energy (glucose). The reaction is as follows:
6CO2 + 6H2O → C6H12O6 + 6O2
- Cellular respiration is the opposite of photosynthesis as it involves the metabolic breakdown of glucose molecule to produce energy usable by the cell (ATP). Cellular respiration combines glucose and oxygen (inputs) to yield carbon dioxide and water (outputs). ATP, motion and heat energy are produced in the process. The equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
