What's the opposite of photosynthesis?

Answer 1

Respiration. Photosynthesis can be summarised as:

6CO2 + 6H2O ---> C6H12O6 + 6O2

while respiration can be summarised as:

C6H12O6 + 6O2 ---> 6CO2 + 6H2O

Of course there is a lot more to it than that.

Answer 2

Photosynthesis is the synthesis of sugar from light, carbon dioxide and water, with oxygen as a by-product. It is arguably the most important biochemical pathway known; nearly all life depends on it.

Cellular respiration is the opposite of photosynthesis: glucose and other compounds are oxidised to produce carbon dioxide, water, and chemical energy. However, both processes actually take place through a different sequence of reactions and in different cellular compartments.

Transpiration is the evaporation of water from aerial parts of plants, especially leaves but also stems, flowers and fruits. Transpiration is a side effect of the plant needing to open its stomata in order to obtain carbon dioxide gas from the air for photosynthesis.

Answer 3

Photosynthesis creates complex sugars by combining carbon dioxide and water. The best known of these sugars is called cellulose, and it is what wood and paper are made from.

The opposite reaction is to break down cellulose into carbon dioxide and water, and the fast way to do this is to burn the cellulose. Cellular respiration does this in a small, controlled way -- fire does it fast.

Answer 4

The opp of photosynthesis is "RESPIRATION" in plants only . Plants respire only at night time or in darkness and consume the synthesized food(frutose or C6H12O6 )at night time. got it !!
however
if u look at the chemical reaction :
6CO + 6H2O -------> 6C6H12O + 6O2 { can only take place in the presenses of light and chlorophyll }
its just a reverse of respiration { here no light is present which is essentioal for photosynthesis. missing an important factor} hope clear !!!!

Answer 5

In a certain sense, it's animal respiration and metabolism. A plant takes in sunlight, water, and carbon dioxide to create sugar and the plant's own substance, as well as an oxygen byproduct. Humans and other animals breathe in that oxygen, and eat sugar and other carbohydrates (derived from plant material), along with meat products (the animals having been nourished with plant material), and then break down the carbohydrates into water and waste carbon dioxide.

Answer 6

chemosynthesis.

Explanation as to why: Photosynthesis depends on sun to obtain energy, whereas chemosynthesis but derives energy from inorganic compounds

Answer 7

Catabolism

Answer 8

YES It's RESPIRATION

Photosynthesis:

Takes Sunlight(Energy) , and CO2
to form C6H1206 (Starch) and O2

WHERE

RESPIRATION:

Takes O2 and Starch(food) and forms
Energy(ATP) and CO2

Answer 9

From memory, I think it's transpiration.

Answer 10

I used to know this...um maybe ....kemosythesis?
