Why are cellular repiration and photosynthesis opposite processes?

Answer 1

The process of photosynthesis is represented by the equation:

CO2 + H2O + sunlight (energy) ----> C6H12O6 +O2

The process of cellular respiration is represented by the equation:

C6H12O6 + O2 ----> CO2 +H2O + ATP (energy)

*C6H12O6 is glucose, a sugar.

As you can see, the products and the reactants of the equations are in reverse order when the two are compared. That means the reactants for photosynthesis are the products of cellular respiration, and vice versa.

Answer 2

Photosynthesis and cellular respiration are considered opposites because:

Photosynthesis takes in CO2 and puts out O2.

Cellular respiration takes in O2 and puts out CO2.

They are interdependent on each other.

the equation for photosynthesis is:

sunlight+carbon dioxide (CO2)+water (H2O)-> carbohydrate+oxygen (O2);

the equation for cellular respiration on the other hand is:

carbohydrate+oxygen (O2)->carbon dioxide (CO2)+water (H2O)+energy (known as ATP)

Cellular respiration is the breakdown of carbohydrates into water and carbon dioxide. Photosynthesis is the synthesis of carbohydrates from carbon dioxide and water.

Answer 3

They are considered opposite cause it is the exact same reaction but inversed:

The reaction for cellular respiration (oxidative metabolism) is:
C6H12O6 (aq) + 6 O2 (g) → 6 CO2 (g) + 6 H2O (l)

chemical reaction for photosynthesis is:
6 CO2 (g) + 6 H2O (i) → C6H12O6 (aq) + 6 O2 (g)

Answer 4

In respiration:

Reactants: Glucose (sugar) + oxygen

Products: carbon dioxide + water + heat energy

In Photosynthesis:

Reactants: Carbon dioxide + water + light energy

Products: Sugar + Oxygen

Answer 5

The process of photosynthesis stores energy in the form of chemical bonds (in carbohydrates including glucose, or sugar) and in the process releases free oxygen by breaking down carbon dioxide. Cellular respiration absorbs free oxygen, to release energy stored in the chemical bonds of food. This oxidation creates carbon dioxide, completing the cycle of carbon through the biosystem.

(Some forms of respiration are anaerobic, not using oxygen, and break down carbohydrates in a different manner, releasing either carbon dioxide or methane. The net result is the same: removing energy from the carbohydrate bonds.)

Answer 6

Cellular respiration;

C6H12O6 + 6O2 -> 6CO2 + H2O

----------------------------------------

Photosynthesis;

6CO2 + 6H2O -> C6H12O6 + 6O2

-----------------------------------------

Chemically speaking it is as plain as the nose on your face.

Answer 7

Photosynthesis is what plants do while respiration is what animals do.

Answer 8

Because photosynthesis forms carbohydrates from carbon dioxide and water, storing energy, while cellular respiration uses oxidation to free that energy, and releases carbon dioxide and water.

Answer 9

You get carbon bi oxide and water from glucose in cellular respiration. You get glucose from from carbon bi oxide and water in photosynthesis.
