where do carbohydrates come from?

Question

how are they formed? Also, how are they formed in our body

Answer 1

Carbohydrates are formed when plant completes both light and dark reaction.

In light reaction when ADP molecules get energy they are converted into ATP.Water breaks into and H+ and OH-.H+ reduces NADP(nicotinamine adenine dinucleotide phpospate) into NADPH2

In dark reaction there is a cycle of reaction called Kalvin-Benson cycle.The whole reaction can be given as follow:

6CO2+12RuBp + 12NADPH2 + 18ATP------------C6H12O6+12RuBP + 12NaDP +6H2o + 18ADP

Answer 2

Carbohydrates comes from plants, by photosynthesis (making glucose from carbon dioxide and water)[by help of sunlight].

6-CO2+ 6-H2O ===> C6H12O6 + 6-O2
carbondioxide+water==>glucose+oxygen

Oxygen is produced as by-product of photosynthesis.
Many molecules of glucose can made into carbohydrates.
Carbohydrates cannot be formed in our body.
Only can be transformed into glycogen which is a form of carbohydrate (from glucose which we get from food).

Answer 3

they are made up of carbon, hydrogen, and oxygen atoms.

starches are broken down by the digestive system sinto simple sugars. thesemolecules are absorbed into the bloodstream nd carried to cells throughout the body. sugars that are not immediately used to suply anergy are converted into the complex carbohydrate glycogen, which is stored in the liver and skeletal muscles.

Answer 4

They are a by product of photosynthesis in plants (used by plants for food). They are not formed in our body, thus we have a need to consume them from plant sources....;

Answer 5

Plants carry out photosynthesis to produce sugar which is then converted to complex sugars and then carbs

Answer 6

photosynthesis
