What are simple sugars known as?
They are sugars that the body can use directly, unlike complex sugars which the body has to first break down. Glucose is an example.
Why is glucose more dominant over other carbohydrates?
Glucose (C6H12O6) is a simple sugar.The structure of glucose is much easier for the body to break down than the structure of many other carbohydrates (complex carbohydrates). For this reason, when you eat a wheat bagel with a can of soda, the sugars from the soda will be absorbed first whereas the sugars in the wheat bagel will take more time and more energy for the body to digest.
For carbohydrates to be oxidized or burned for energy they must first be broken down to what?
For carbohydrates to be oxidized or burned for energy, they must first be broken down into simple sugars (glucose) through the process of digestion. Glucose can then enter cells and undergo further processes such as glycolysis and the citric acid cycle to produce energy in the form of ATP.
What is the first macromolecule to be enzymatically attacked immediately following ingestion?
Carbohydrates are the first macromolecules to be enzymatically attacked following ingestion. Digestive enzymes in the mouth and stomach break down carbohydrates into simpler sugars like glucose that can be absorbed by the body.

What are the building blocks of carbohydrates?
The first class of biomolecules we will discuss are the carbohydrates. These molecules are comprised of the elements carbon (C), hydrogen (H), and oxygen (O). Commonly, these molecules are known as sugars. Carbohydrates can range in size from very small to very large. Like all the other biomolecules, carbohydrates are often built into long chains by stringing together smaller units. This works like adding beads to a bracelet to make it longer. The general term for a single unit or bead is a monomer. The term for a long string of monomers is a polymer. Examples of carbohydrates include the sugars found in milk (lactose) and table sugar (sucrose). Depicted below is the structure of the monomer sugar glucose, a major source of energy for our body. Building blocks are simple sugars, or monosaccharides. i thought carbon ,hydrogen and oxygen were the atoms involved, not the building blocks.
Carbohydrates are needed to spare protein in the body?
Yes. When the body needs energy, it digests carbohydrates and sugars at first. If none are available, it begins to digest your fat. And if that isn't available, it begins digesting protein.
Which of these is the first step in chemical digestion?
The first step in chemical digestion occurs in the mouth with the enzyme amylase breaking down carbohydrates into simpler sugars.
Contains the enzyme used in the first step in digestion?
Saliva contains the enzyme amylase, which is used in the first step of digestion to break down carbohydrates into simpler sugars.
What common polysaccharides carbohydrates found in plants?
Poly means "many" and saccharidemeans "sugar." Polysaccharides are molecules consisting of at least three sugars strung together. We call them starches. These are generally very long chains that contain a lot of energy. They have a lower glycemic index than simple or double sugars because they are so much larger and therefore digest more slowly and require certain enzymes that are found in the intestines. Simple sugars, like fructose, can be absorbed directly into the bloodstream without being "digested" first because they are basically already digested.
How are sugars transported?
Simple sugars are considered carbohydrates, like starches are, and effects the blood sugar. The circulatory system is responsible for transporting the sugar through the body, first out of the digestive tract and then into the cells.
Where do sugars go after absorption?
After absorption in the small intestine, sugars enter the bloodstream and are transported to various tissues and organs throughout the body to provide energy. Excess sugars may be stored in the liver and muscle cells as glycogen for future energy needs. Any remaining excess sugars can be converted into fat and stored in adipose tissue for long-term energy storage.
