Question

2...the tertiary structure of a protein refers to the

		order of amino acids along the chain
		three dimensional structure of the molecule
		alpha helix or pleated sheet arrangement
		interaction of several peptide chains

A....Carbohydrate molecules

		form the regulatory molecules known as enzymes.
		contain the genetic information found in cells.
		are the body's most readily available source of energy.
		are composed of C, H, O, and N atoms.
		are the building blocks of cellular membranes.

B....Lipids which are used to store energy and/or cushion structures (i.e. eye, kidney) are called:

		triglycerides
		fatty acids
		phospholipids
		prostaglandins

C.....A solution that contains equal numbers of hydrogen and hydroxide ions is

		alkaline
		acidic
		basic
		neutral

D .....A molecule composed of glycerol, two fatty acids and a phosphate group is a

		saturated fat
		glycogen
		cholesterol
		phospholipid

E....Which of the following are dissachrides?

		glycogen and starch
		glucose and fructose
		sucrose and galactose
		lactose and sucrose

F.....A nucleotide consists of

		a five-carbon sugar, a nitrogenous base, and a phosphate group.
		a phosphate group and a nitrogenous base.
		a five-carbon sugar and a nitrogenous base.
		a five-carbon sugar and an amino acid.
		a five-carbon sugar and phosphate group.

G...Amino acids are different from each other because of the

		carboxyl end of the molecule
		amino end of the molecule
		structure of the side chain (R group)
		way that they form their peptide bond

H......Molecules that store and process genetic information are the

		proteins.
		lipids.
		nucleic acids.
		steroids.
		carbohydrates.

J.....Lipids that are produced by nearly every tissue in the body and that act as local regulators of metabolism are the

		monoglycerides.
		prostaglandins.
		glycolipids.
		steroids.
		phospholipids.

Answer 1

2)First options means the primary structure.

The second option means the tertiary structure .

Third option means secondary structure.

Fourth option means the quarternary structure.

So answer is second option.

A)Carbohydrates are the most readily available source of energy for the body.

Enzymes are proteins; nucleic acids contain the genetic information found in cells,proteins are made up of C,H,O,N atoms and lipids and proteins make up the cellular membrane.

B)Fatty acids

C)They are called neutral solutions.

D)Phospholipid

E)Sucrose (glucose +fructose) ,Lactose (glucose + galactose)

F)Five carbon sugar, nitrogenous base,phosphate group

G)They are different because of the structure of the side chain.

H)Nucleic acids

J)Prostaglandins
