Answer 2

Photosynthesis is similar to cellular respiration in the sense that the equation of one is the reverse of the equation of the other.

The original source of energy that is introduced into the ecosystem comes from the sun. This energy is passed along the food chain.

The equation that models cellular respiration is the equation; C6H12O6 + 6O2 → 6H2O + 6CO2 + Energy. Recall that cellular respiration involves the breakdown of glucose in the presence of oxygen. The compound that is involved in cellular respiration is oxygen.

The Calvin cycle is the light-independent (does not need light) step of photosynthesis and happens in the stroma.

The products of photosynthesis are carbon dioxide and water as we can see from the reaction; 6CO2 + 6H2O → C6H12O6 + 6O2.

Electrolysis does not form a part of cellular respiration. Glycolysis,  electron transport chain and the Krebs cycle are steps of cellular respiration.

The events shown in the picture occurs in the chloroplasts. The image shown the biochemical processes involved in photosynthesis.

During cellular respiration, glucose is split into its constituent molecules which are water and carbon dioxide when it reacts with oxygen.

The equation of photosynthesis is the reverse of the equation of cellular respiration.
