Answer 2

Reducing agents

Question 3

(split, with the addition of H,O) into simpler
carbohydrates .

Answer 4

Monosaccharides

Question 5

fructose and galactose are examples of ______

Answer 5

hexoses

Question 6

combinations of two monosaccharides.

Answer 6

Disaccharides

Question 7

maltose

Answer 7

(glucose + glucose),

Question 8

Answer 8

(glucose+ fructose)

Question 9

lactose

Answer 9

(glucose + galactose).

Question 10

contain 3-6 monosaccharides.

Answer 10

Oligosaccharides

Question 11

contain more “than 6 monosaccharides

Answer 11

Polysaccharides

Question 12

starches, which are long chain polymers of a1pha-D-glucose in the form of

Answer 12

amylose, amylopectin, and glycogen

Question 13

is an unbranched chain of glucose residues connected by alpha 1,4 linkages

Answer 13

Amylose

Question 14

apart from being a longer word, is more complex than amylose in having additional, alpha-I ,6 linkages , which result in branching

Answer 14

Amylopectin

Question 15

(“animal starch”) resembles amylopectin but branches
even more. is the main storage forn of carbohydrates
in humans,

Answer 15

Glycogen

Question 16

has beta-I,4 linkages, bonds which human enzymes
cannot break, but the bacterial enzymes in cows
can. Therefore cows eat grass, but we don’t.

Answer 16

Cellulose

Question 17

When carbohydrates attach to proteins and lipids,

they form ________ and ________.

Answer 17

glycoproteins and glycolipids

Question 18

Carbohydrateland has its own powerhouse, called the

________

Answer 18

hexose monophosphate (HMP) shunt
pentose phosphate pathway,
the pentose shunt,
phosphogluconate oxidative pathway.

Question 19

This powerhouse does not produce ATP energy molecules, as does the Main Powerhouse, but it does produce NADPH

Answer 19

hexose monophosphate (HMP) shunt
pentose phosphate pathway,
the pentose shunt,
phosphogluconate oxidative pathway.

Question 20

a molecule important for its “reducing” power.

Answer 20

NADPH

together to form _______, which is stored in the _____, _____ _____, and many other ______.

Answer 21

glycogen

liver, skeletal muscle, and many other tissues.

Question 22

______ is an anabolic hormone that “ signals the fed
state”. It also facilitates entry of glucose
into muscle and fat cells.

Answer 22

Insulin
