b. 40-50%
c. 50-60%
d.60-70% - answerd.60-70%

,1. what is it?
2. where is it stored? - answer1. The stored energy substance produced bythe
polymerization (chaining) of glucose.
2. stored mainly in the liver and muscle tissues, as well as in other body tissues

sugar per day.

3. galactose
4. xylose
5. ribose

,3. lactase
4. sucrase
The ____________ serve(s) as the major metabolizer and regulator of dietary
carbohydrates. This blood glucostat's job is to convert excess incoming glucose into
glycogen (glycogenesis) in times of plenty and to reconvert glycogen to glucose
(glycogenolysis) during periods of food restriction, thereby maintaining an adequate
level of glucose in the bloodstream.
a. pancreas
b. kidneys
c. liver - answerc. liver
The lack of protein in a typical individual's diet caused the body to catabolize precious
muscle tissue, if not, vital organs, as its source of protein to sustain itself. Catabolism of
muscle tissue not only makes the individual weaker, but also lowers ______________.
This is because muscle tissue requires more energy to sustain itself: the more muscle
one has, the faster the ____________________ will be. It is the body's innate defense
mechanism for conserving energy.
a. metabolism
b. glycogenesis
c. insulin secretion - answermetabolism
Each type of carbohydrate has a glycemic index, which is a number (1-100) given to
determine the rate at which the carbohydrate is broken down into glucose. The lower
the number, the 1(faster/ longer) it takes to break down, and the higher the number, the
2(faster/longer) - answer1 LONGER
2 FASTER
