Question | Answer |
---|---|
Hydrogen, Carbon, and Oxygen make up? | Carbohydrates |
Simple carbohydrates contain only 1 or 2 sugar molecules (Simplest of all sugars)? | Monosaccharide |
Glucose, Fructose, and Galactose are all? | Monosaccharides |
Glucose is also known as? | Dextrose |
Fruit sugar, sweetest of all natural sugars? | Fructose |
Which sugar is in lactose? | Galactose |
Sucrose, Maltose, and Lactose are all? | Disaccharides |
Glucose + Fructose = | Sucrose |
Which disaccharide breaks down starch (not found naturally in foods)? | Maltose |
Glucose + Galactose = (least sweetest sugar)? | Lactose |
True or False. Another name for glucose is dextrose and is the sugar into which the body makes all digestible carbohydrates? | True |
Complex carbohydrates, that do not taste sweet. Starch, glycogen, and fiber are types of? | Polysaccharides |
Which stores in the fat cells if not used? | Glycogen |
Generally considered a group name for polysaccharides that cannot be digested by human enzymes? | Fiber |
Source of energy for colon lining? | Fiber |
Bran, endosperm, and germ make up? | Whole grains |
Rich in starch, but lack the fiber, vitamins trace minerals, fat, and phytochemicals found in whole grains? | Refined grains |
Required to be fortified. Examples include: white flour, white bread, white rice, and refined cornmeal? | Enrichment |
Most carbohydrate digestion occurs in the? | Small Intestine |
Are the only form of carbohydrates the body is able to absorb intact? | Monosaccharides |
95% of what is digested usually within 1 to 4 hours after eating? | Starch |
Fructose and galactose are converted to glucose in the? | Liver |
Blood glucose concentration begins to drop Pancreas releases glucagon, stimulates liver to release glucose? | Postprandial state |
Balance between catabolism and anabolism = ? | Glucose metabolism |
Brain is totally dependent on what for energy? | Glucose |
When the body does not have an adequate intake of glucose, the formation of ketone bodies increases. Increased production of ketones has several side effects. What is one of these side effects? | Sodium depletion |
A component of every living cell. Accounts for 20% of adult weight. Immune to the controversy over optimal intake? | Protein |
Basic building blocks of protein? | Amino Acids |
Composed of Carbon, Hydrogen, Oxygen, and Nitrogen Atoms? | Protein |
9 are considered what, because the body cannot ake them-indispensable; they must be consumed through food? | Essential |
11 are considered what, because they can be made by the body-dispensable? | Nonessential |
Amino acids are the building blocks of protein. They are classed as either essential or nonessential. Which of these is an essential amino acid: Glycine, Aspartic Acid, Tyrosine, or Leucine? | Leucine |
Amino acids, and sometimes a few depeptides or larger peptides, are absorbed through the mucosa of the? | Small intestine |
Reflects the state of balance between protein breakdown and protein synthesis? | Nitrogen balance |
Nitrogen Balance when protein synthesis exceeds protein breakdown? | Positive |
Nitrogen Balance an undesirable state that occurs when protein breakdown exceeds protein synthesis? | Negative |
True or False. Healthy adults are in a positive state of nitrogen balance? | False |
2 proteins that when combined provide adequate amounts and proportions of all essential amino acids needed to support protein synthesis? | Complementary proteins |
Sometimes the recommended daily allowances do not apply to a diet. Why is this true? | Intended for healthy people. |
