Sagot :
Answer:
In Short The correct answer is B...
Explanation:
Here are most of the functions of carbohydrates altogether:
Provide instant energy to the body. :This appears to be the primary function of carbohydrates in the body. ...
Reserve food: Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.
Carbohydrates form other biomolecules.
Detoxification of the body by metabolism
Carbohydrates participate as reaction intermediates in some vital reactions. This function of carbohydrates is seen extensively in various cellular reaction.
For example, one of the vitamins, Vitamin B2 also called Riboflavin has a ribose sugar moiety. This ribose is a four carbon type of carbohydrate monomer by its chemical structure. It is involved in vital reactions at the organ and cellular level. Similarly, carbohydrates are also chemical constituents of many hormones, vitamins, enzymes, etc.
Carbohydrates form a part of DNA and RNA in the form of deoxyribose and ribose sugars. These are five carbon monosaccharides formed form heptulose sugars by the pseudo-heptulose pathway.
They are constituents of all the cellular organelles. Carbohydrates are also components of cell organelles like the cell membrane, mitochondria, nucleus, endoplasmic reticulum, etc. They provide structural integrity, mechanical strength in combination with proteins and lipids. They help make up the body mass by being included in all the parts of the cell and tissues. For example, in cell membranes, there are two constituents, i.e., glycolipid layer and glycoprotein layer. Here the term “glyco” is a carbohydrate.
8. Transport of oxygen: Glucose is taken by red blood cells. These are the types of blood cells which lack mitochondria and other cell organelles required for producing energy. In such a case, the ATP is produced by a non-oxidative pathway with the end product as lactose and ATP.
This energy thus produced is necessary for hemoglobin to bind to oxygen molecules. These bound oxygen molecules are transferred from lungs to the different tissues.
9. Aid in gut motility: Our diet has carbohydrates in greater proportions because, it aids in bowel movement. When you suffer from constipation, doctors first prescribe you bran and other carbohydrate material like Ispaghula. The carbohydrates in these material is in the form of fibrous material. When they are ingested, their material absorbs water in the guts, swells and increases the load.
This load is useful to increase intestinal motility and expulsion of waste (feces). Thus carbohydrates help clear gut and prevent constipation. Hence, when you feel constipated, have banana fruit and notice the change.
They play a role in other physiological roles. Since they are components of many bio-molecules, they have further roles in body physiology. They have a role in blood clotting, immunity, fertilization. Thus they take part in many physiological reactions.
Answer:
B. Carbohydrates are used to store energy and provide structure/support in living things.
Explanation:
The two functions of carbohydrates are to store energy and provide structure/support in living things.
