Why is 12 h2o used in photosynthesis?
— To answer why 12 molecules of water are required, here is the explanation. –Products of light reaction required in dark reactions to form one molecule of glucose are 12 molecules of NADPH and 18 molecules of ATP. –Now for producing 12 molecules of NADPH , total 12 molecules of water are required.
What is c6h1206 6O2?
oxidation reaction is : C6H12O6 + 6O2 -> 6CO2 + 6H2O. Yields 2755 kJ/mole of glucose. The reverse of this reaction – combing carbon dioxide and water to make sugar – is known as photosynthesis. Photosynthesis is the process responsible for storing all the energy we extract from fossil fuels, crops, and all of our food.
What is the chemical formula of carbohydrates?
Carbohydrates can be represented by the stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule. Therefore, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. The origin of the term “carbohydrate” is based on its components: carbon (“carbo”) and water (“hydrate”).
What is the general formula for most carbohydrates?
The general formula for any carbohydrate is (CH2O)x where x is any number between three and eight. The most common monosaccharides (hexoses) are glucose, galactose, and fructose.
In what 3 forms do carbohydrates exist?
Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides.
What makes something a carbohydrate?
Medical Definition of Carbohydrates Carbohydrates: Mainly sugars and starches, together constituting one of the three principal types of nutrients used as energy sources (calories) by the body. Carbohydrates can also be defined chemically as neutral compounds of carbon, hydrogen and oxygen.
How are carbohydrate classified?
How are carbohydrates classified? Carbohydrates are divided into four types: monosaccharides, disaccharides, oligosaccharides, and polysaccharides. Monosaccharides consist of a simple sugar; that is, they have the chemical formula C6H12O6. Disaccharides are two simple sugars.
What is an example of a carbohydrate?
Following are the important examples of carbohydrates:
- Glucose.
- Galactose.
- Maltose.
- Fructose.
- Sucrose.
- Lactose.
- Starch.
- Cellulose.
Which one is a carbohydrate?
Carbohydrates (also called carbs) are a type of macronutrient found in certain foods and drinks. Sugars, starches and fiber are carbohydrates. Other macronutrients include fat and protein. Your body needs these macronutrients to stay healthy.
What are the five sources of carbohydrates?
Carbohydrates are found in a wide array of both healthy and unhealthy foods—bread, beans, milk, popcorn, potatoes, cookies, spaghetti, soft drinks, corn, and cherry pie. They also come in a variety of forms. The most common and abundant forms are sugars, fibers, and starches.
What are the two main sources of carbohydrates?
The two main forms of carbs are:
- simple carbohydrates (or simple sugars): including fructose, glucose, and lactose, which also are found in nutritious whole fruits.
- complex carbohydrates (or starches): found in foods such as starchy vegetables, whole grains, rice, and breads and cereals.
What is the healthiest source of carbs?
While all carbs break down into glucose, the best carbs for your health are the ones you’ll eat in their closest-to-nature state as possible: vegetables, fruit, pulses, legumes, unsweetened dairy products, and 100% whole grains, like brown rice, quinoa, wheat, and oats.
