Science Lesson 2 Flashcards
Nutrients, Macro-nutrients, Metabolism
Which of the following are classified as macronutrients?
Carbohydrates, proteins, fats, water, and air
Which macronutrient is a primary source of energy for our cells?
Carbohydrates
The constituents of proteins are called ________________________ and are the building blocks of life.
Amino Acids
What macronutrient acts as a solvent for chemical reactions and transports dissolved compounds into and out of cells?
Water
_______________________ breaks glucose into carbon dioxide, water, and adenosine triphosphate, which supplies the energy needed for other chemical reactions.
Oxygen
These types of carbohydrates contains one or two sugars that are released and digested very quickly and tend to spike the blood sugar.
Simple carbohydrates
All of the following are classified as monosaccharides EXCEPT:
Debose
Oligosaccharides have all of the following functions EXCEPT:
Form proteins
________________________ forms a gel-like material when it is exposed to water, which slows the movement of food through the digestive tract.
Soluble fiber
________________________ is a measure of how quickly blood sugar levels rise after eating a certain food. Fifty-five or less is considered low, while 70 or more is high.
Glycemic index
_________________________ is/are never fully absorbed in the small intestine and traverses to the large intestine where intestinal bacteria ferment it.
Resistant starch
_________________________ strengthen cells. For instance, collagen makes up 25 percent of the body’s total protein, and it strengthens bones and connective tissue.
Structural proteins
__________________________ are proteins that break molecules down to be absorbed by the body. Without these proteins, metabolic processes would happen too slowly and we would die.
Enzymes
A good estimate to determine protein needs is to multiply your weight in pounds by ______________ to get the amount of protein in grams you should have daily.
0.36
True or False: Nearly all vegetables, grains, nuts and seeds contain protein.
True?
