Glycogen is
- A.
A highly branched polysaccharide.
- B.
Stored in the absence of dietary carbohydrate.
- C.
A straight chain of glucoses linked together.
- D.
A hormone for blood glucose regulation.
Correct Answer
A. A highly branched polysaccharide.Explanation
Glycogen is a highly branched polysaccharide. Polysaccharides are complex carbohydrates composed of multiple sugar units. Glycogen is the storage form of glucose in animals and humans, and it is primarily stored in the liver and muscles. The highly branched structure of glycogen allows for efficient storage and quick release of glucose when needed for energy. This branching allows for multiple sites of enzymatic action, increasing the rate of glucose release. Therefore, the correct answer is that glycogen is a highly branched polysaccharide.Rate this question:

Which of the following is not a rich source of viscous (soluble) fibers?
- A.
Fruits
- B.
Oatmeal
- C.
Whole wheat bread
- D.
Legumes
Correct Answer
C. Whole wheat breadExplanation
Whole wheat bread is not a rich source of viscous (soluble) fibers. While it does contain some dietary fiber, it is primarily made from refined wheat flour, which has had the bran and germ removed. These are the parts of the wheat grain that contain most of the fiber. Therefore, whole wheat bread may have less soluble fiber compared to other options like fruits, oatmeal, and legumes, which are known to be good sources of viscous fibers.Rate this question:

Which of the following is true about carbohydrate digestion?
- A.
Carbohydrate digestion is assisted by cooking, which softens tough skins.
- B.
Carbohydrate digestion begins in the stomach.
- C.
Chewing food does not assist in carbohydrate digestion.
- D.
Saliva production does not influence starch digestion.
Correct Answer
A. Carbohydrate digestion is assisted by cooking, which softens tough skins.Explanation
Cooking can break down the tough skins of carbohydrates, such as potatoes or beans, making them easier to digest. This is because cooking helps to soften the fibrous structure of these foods, allowing digestive enzymes to access and break down the carbohydrates more efficiently. Chewing food does assist in carbohydrate digestion as it breaks down the food into smaller pieces, increasing the surface area for enzymes to act upon. Saliva production does influence starch digestion as saliva contains an enzyme called amylase, which begins the breakdown of starch into simpler sugars. However, carbohydrate digestion does not begin in the stomach, but rather in the mouth with the action of amylase in saliva.Rate this question:

A disaccharide is formed by the chemical bonding of
- A.
Two monosaccharides.
- B.
Two polysaccharides.
- C.
One monosaccharide and one polysaccharide.
- D.
Two oligosaccharides.
Correct Answer
A. Two monosaccharides.Explanation
A disaccharide is a type of carbohydrate that is formed by the chemical bonding of two monosaccharides. Monosaccharides are simple sugars, such as glucose and fructose, that cannot be further broken down into smaller carbohydrates. When two monosaccharides undergo a condensation reaction, a glycosidic bond is formed, resulting in the formation of a disaccharide. Examples of disaccharides include sucrose (glucose + fructose) and lactose (glucose + galactose). Therefore, the correct answer is two monosaccharides.Rate this question:

Lactose intolerance is caused by
- A.
A milk allergy.
- B.
Lactase deficiency.
- C.
Milk bacteria.
- D.
Intestinal bacteria.
Correct Answer
B. Lactase deficiency.Explanation
Lactose intolerance is caused by lactase deficiency. Lactase is an enzyme that breaks down lactose, the sugar found in milk. When there is a deficiency of lactase, the body is unable to properly digest lactose, leading to symptoms such as bloating, diarrhea, and stomach cramps. This is different from a milk allergy, which is an immune response to proteins in milk, and is also different from milk bacteria or intestinal bacteria, which are not direct causes of lactose intolerance.Rate this question:

The main function of glucose is to
- A.
Serve as raw material to build tissue.
- B.
Work with enzymes to carry out chemical reactions.
- C.
Repair tissue.
- D.
Supply energy.
Correct Answer
D. Supply energy.Explanation
Glucose is a type of sugar that is the primary source of energy for the body. When consumed, it is broken down during cellular respiration to release energy that is used for various metabolic processes. Glucose is converted into ATP (adenosine triphosphate), which is the molecule that provides energy to cells. Therefore, the main function of glucose is to supply energy to the body.Rate this question:

Which of the following is not characteristic of Type 1 diabetes mellitus?
- A.
Arises most commonly in adulthood
- B.
Associated with a tendency to develop ketosis
- C.
Sometimes caused by viral infection
- D.
Has a genetic link
Correct Answer
A. Arises most commonly in adulthoodExplanation
Type 1 diabetes mellitus is typically diagnosed in childhood or adolescence, not adulthood. It is an autoimmune condition where the body's immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas. This leads to a lack of insulin, resulting in high blood sugar levels. Type 1 diabetes is associated with a tendency to develop ketosis, which occurs when the body breaks down fat for fuel instead of glucose. It can be caused by viral infections and has a genetic link, meaning it can run in families.Rate this question:

When eating a high-fiber diet one should
- A.
Restrict fluid intake.
- B.
Not be concerned about consuming large amounts.
- C.
Avoid foods that are not whole grain.
- D.
Increase fluid intake.
Correct Answer
D. Increase fluid intake.Explanation
When eating a high-fiber diet, it is important to increase fluid intake. This is because fiber absorbs water and helps to soften the stool, preventing constipation. Without adequate fluid intake, the fiber can cause digestive problems such as bloating and discomfort. Therefore, increasing fluid intake is necessary to ensure the proper digestion and absorption of fiber in the body.Rate this question:

Which of the following is not true of dietary fibers?
- A.
They are mostly polysaccharides.
- B.
The bonds between sugar units cannot be broken by human digestive enzymes.
- C.
They cannot be absorbed by the small intestine.
- D.
They are absorbed in the large intestine.
Correct Answer
D. They are absorbed in the large intestine.Explanation
Dietary fibers are mostly polysaccharides, meaning they are made up of multiple sugar units. The bonds between these sugar units cannot be broken down by human digestive enzymes, so they pass through the digestive system without being fully digested. Instead of being absorbed by the small intestine, dietary fibers reach the large intestine where they can be fermented by gut bacteria. Therefore, the statement that dietary fibers are absorbed in the large intestine is not true.Rate this question:
