Polysaccharides

34
Q

Starch and glycogen are examples of (?),
while cellulose and chitin are examples of (?).

A

storage polysaccharides, structural polysaccharides

35
Q

is a storage of carbohydrate in plants composed entirely of glucose molecules.

It is commonly found in potato
tubers, cassava, carrots, corn, and cereals.

A

Starch

36
Q

is a storage carbohydrates in animals, which accumulates in the liver and muscle cells of vertebrates.

A

Glycogen

37
Q

Glycogen and starch are ideal storage
polysaccharides for the following
reasons:

(see answer agad)

A

Both can easily broken down into glucose molecules when needed

Both are insoluble in water, thus, do not affect osmotic pressure in cell.

Both have compact shape, thus, occupy less space.

Both cannot diffuse through cell membranes
because of their relatively large size

38
Q

is a rich supply of glucose, but human and many animals are not capable of digesting it.

Ruminants, eat cellulose-rich materials such as grass and hay but rely on bacteria present in their digestive tract to digest cellulose.

A

Cellulose

39
Q

is a structural polysaccharide in the outer coverings of crustaceans and insect.

It has protective and supportive functions.

It is highly insoluble and does not expand in water, making animals survive aquatic environments.

is also an effective source of surgical sutures or threads due to its flexibility and strength.

Aside from medical uses chitin is also used in industrial, pharmaceutical, and biotechnological

A

Chitin

40
Q

are organic substances that include fats and fat-lie substances, such as phospholipid, wax, steroid, and sphingolipid.

are generally hydrophobic substances and are insoluble in water but soluble in organic solvents, such as benzene, ether, and chloroform.

Lipids is made up of carbon, hydrogen, and oxygen, but contain less oxygen in proportion to hydrogen.

A

Lipids

41
Q

Lipids in living organisms have the following functions:

(see answer agad)

A

Solvent for fat-soluble vitamins and hormones.

Prevents water loss from skin surface. The thin layer of oil secreted by sebaceous glands in the skin prevents water evaporation.

Essential parts of cell structures such as
cell membrane.

Insulating material to prevent heat loss and
protection against extreme cold.

Source and storage of energy. Lipids provide twice as much energy per pound as carbohydrates.

42
Q

Fats can be broken down into simpler compounds by the addition of water or hydrolysis. Three molecules of water are
needed to break one molecule of fat into its component glycerol and three fatty acids with the aid of an enzyme called

A

lipase

43
Q

are solid at room temperature. These are
mostly found in animals. Lard, margarine, and butter

A

Saturated fatty acids

44
Q

occur in liquid state at room temperature.
They are mainly found in plants- vegetable oil and corn oil.

A

Unsaturated fatty acids

45
Q

are organic compounds that function for the storage of genetic information, which is transmitted from one generation to the next in all living organisms.

also function in protein synthesis, as they carry the code needed in the formation of specific proteins.

A

Nucleic acids

46
Q

The types of nucleic acids in living organisms are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Both types of nucleic acids are made up of the basic building blocks called

A
