Answer 1

Photosynthesis and cellular respiration are two vital biochemical processes that are interconnected in the ecosystem, forming a biological cycle of energy conversion and matter recycling.

Photosynthesis occurs primarily in plants, algae, and some bacteria. It involves the conversion of light energy from the sun into chemical energy stored in glucose. The reactants of photosynthesis are carbon dioxide (CO2) and water (H2O), which are absorbed from the environment. Using sunlight, these reactants undergo a series of reactions in the chloroplasts of plant cells to produce glucose (C6H12O6) and oxygen (O2). Thus, the overall chemical equation for photosynthesis can be summarized as:

\[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{light energy} \rightarrow \text{C}6\text{H}{12}\text{O}_6 + 6 \text{O}_2 \]

In this equation, glucose and oxygen are the products of photosynthesis.

Cellular respiration is the process that occurs in the cells of all living organisms, where glucose is broken down to release energy for cellular activities. The reactants of cellular respiration are glucose (C6H12O6) and oxygen (O2), which are derived from the products of photosynthesis. During cellular respiration, glucose undergoes oxidation in the presence of oxygen to produce carbon dioxide (CO2), water (H2O), and adenosine triphosphate (ATP), the energy currency of the cell. The overall chemical equation for cellular respiration can be summarized as:

\[ \text{C}6\text{H}{12}\text{O}_6 + 6 \text{O}_2 \rightarrow 6 \text{CO}_2 + 6 \text{H}_2\text{O} + \text{energy (ATP)} \]

In this process, carbon dioxide and water are the products of cellular respiration.

The relationship between these two processes can be illustrated as a cyclical pattern: the products of photosynthesis (glucose and oxygen) are the reactants for cellular respiration, while the products of cellular respiration (carbon dioxide and water) are the reactants for photosynthesis. This interdependence underscores the balance of ecosystems, where plants convert solar energy into chemical energy, and organisms, including plants, rely on that energy to fuel their own metabolic processes through respiration.
