Q

Three disaccharides are important in nutrition

A

MALTOSE
SUCROSE
LACTOSE

20
Q

Is the most familiar of the 3 disaccharides and is what people mean when they speak of sugar

21
Q

Table or white sugar, what is that

22
Q

this sugar is usually obtained by refining to choose from sugar beets or sugarcane to provide the brown white and powdered sugar sa bailable in the supermarket but it occurs naturally and many fruits and vegetables

23
Q

When a person eats a food containing sucrose, enzymes in the digestive tract split the sucrose into its

A

GLUCOSE AND FRUCTOSE components

24
Q

Is the principal carbohydrate of milk

25
Most human infants are born with digestive enzymes necessary to split lactose into its two monosaccharides part
GLUCOSE AND GALACTOSE
26
Is the third disaccharide
MALTOSE
27
Is a plant sugar that consists of two glucose units Is produced whenever a starch breaks down - as happens in plant when they break down there is stored starch for energy and start to sprout and in human beings during carbohydrate digestion
MALTOSE
28
Are composed almost entirely of glucose
POLYSACCHARIDES
29
Three types of polysaccharides are important in nutrition
GLYCOGEN STARCH FIBERS
30
Glycogen is found in
MEATS ONLY
31
The human body stores much of its glucose as glycogen in the
LIVER AND MUSCLES
32
Molecules are made of chains of glucose that are more highly branched than those of starch molecules
GLYCOGEN
33
Is a long straight or branched chain of hundreds or thousands of glucose units linked together
STARCH
34
When a person eats the plant, the body is splits the starch into
GLUCOSE UNITS
35
Are the structural parts of plants and thus are found in all plant derived foods - vegetables fruits whole grains and legumes
DIETARY FIBERS
36
Most dietary fibers are
POLYSACCHARIDES
37
If blood glucose falls below normal a person may become
DIZZY AND WEAK
38
If blood glucose rises substantially above normal the person may become
FATIGUE
39
A disorder characterized by elevated blood glucose
DIABETES
40
Blood glucose homeostasis is regulated primarily by two hormones
INSULIN GLUCAGON
41
Which moves glucose from the blood into the cells
INSULIN
42
Which brings glucose out of a storage when blood glucose falls (as occurs between meals)
GLUCAGON
43
Facilitating blood glucose uptake by the
MUSCLES AND ADIPOSE TISSUE
44
Stimulating glycogen synthesis in the
LIVER
45
a hormone that is secreted by special cells in the pancreas in response to low blood glucose concentration and that elicits release of glucose from storage
GLUCAGON
46
Is a member of the class of compounds called lipids
FAT
