Answer:

Hereditary information

Question 2: Proteins are the workhorses of the "BLANK"

Answer:

Cell Question 3: The remarkable thing about macromolecules is that dozens, sometimes hundreds or thousands, of noncovalent bonds form at the "BLANK"

Answer:

Same time.Question 4: Every chemical reaction in a cell-and there are thousands of them going on all the time-is carried out by an "BLANK"

Answer:

Enzyme.

Question 5: Individual noncovalent bonds are "BLANK" enough to form spontaneously, but also break easily.

Answer:

Weak Question 6: But every protein is built from the same raw materials-20 kinds of "BLANK"

Answer:

Amino acids.Question 7: Once all of the amino acids in a particular protein are linked together, this polypeptide spontaneously folds into a specific "BLANK" shape.

Answer:

Three-dimensional Question 8: Each monomer of RNA is a type of nucleotide, called a "BLANK" , which is made up of a ribose sugar linked on one side to a trio of phosphates and on the other side to a nitrogenous base.

Answer:

Ribonucleotide Question 9: Hydrolysis is essentially the opposite of a "BLANK" reaction.

Answer:

Dehydration Question 10: Fatty acids that contain a "BLANK" between two of the carbon atoms are called.

Answer:

Double bond, Unsaturated

Question 11: Phospholipids and triglycerides are both made from the same

components:"BLANK" and "BLANK" .

Answer:

Fatty acids and Glycerol

Question 12: Hydrogen bonds and ionic bonds are examples of

Answer:

Noncovalent bonds.

Question 13: Nucleotides

Answer:

Nucleic Acid

Question 14: A substance composed of similar units bonded together.

Answer:

Polymer Question 15: "BLANK" are sometimes grouped among the macromolecules, but "BLANK" are not polymers. This is because they are not built from monomers joined together via dehydration reactions.

Answer:

Lipids

Question 16: Glycerol is a type of "BLANK" .

Answer:

Sugar Question 17: High energy molecule drives a water molecule from two "BLANK" , enabling the covalent bond to from.

Answer:

Adjacent sugar molecules Question 18: Humans are made of cells, and these cells are made of water, some small molecules, ions, and specialized structures called

Answer:

Macromolecules Question 19: One way that we get the energy we need is to break down stored "BLANK" into "BLANK" which is then used by our cells to make ATP.

Answer:

Glycogen into glucose

Question 20: Amino acids

Answer:

Proteins

Question 21: A molecule that contains a large number of atoms.

Answer:

Macromolecules Question 22: "BLANK" is made of two nucleic acid polymers that wind around each other to form the famous DNA double helix

Answer:

Deoxyribonucleic acid (DNA)

Question 23: Molecules composed of amino acids joined by peptide bonds.

Answer:

Proteins

Question 24: Sugars and starches, which the body breaks down, into glucose.

Answer:

Carbohydrates Question 25: RNA molecules are essential for converting the information stored in DNA into "BLANK"

Answer:

Proteins.Question 26: The human body is mostly water, about "BLANK" percent by weight.

Answer:

70% Question 27: Fatty acids are long hydrocarbon chains with a "BLANK" on one end.

Answer:

Carboxylic acid
