Answer 1

Destroys the reactants substances into molecular rubble .

Question 2

Anabolic Reactions :

Answer 2

Reassembles that rubble into new and bigger products.

Question 3

Anabolism :

Answer 3

Anabolic reactions construct things and consume energy .

Question 4

Catabolism :

Answer 4

Break down molecules and release energy .

Question 5

Nutrients:

Answer 5

The molecules that your body is forever breaking up and then rebuilding , only to have them break apart again.

Question 6

Biochemistry :

Answer 6

Studying the chemical aspects of life.

Question 7

Matter :

Answer 7

Anything that has mass and occupies space.

Question 8

Atomic Number:

Answer 8

The number of protons in the nucleus .

Question 9

Atomic Mass:

Answer 9

The number of protons and neutrons combined .

Question 10

The farther an orbital extends from the nucleus , the _______ its energy level.

Answer 10

Higher

Question 11

Neutral Solutions :

Answer 11

pH of 7 (such as water )

Question 12

Acidic Solutions :

Answer 12

pH lower than 7

Question 13

Base Solutions :

Answer 13

pH higher than 7

Question 14

Triglycerides :

Answer 14

Are Lipid molecules formed by a glycerol unit or “head” joined to three fatty acid “tails “
- Triglycerides are useful in storing energy in cells for later use.

Question 15

Phospholipids :

Answer 15

A lipid containing a phosphate in its molecule .
-Because the tails repel water , phospholipids molecules often arrange themselves so that their tails face away from water.

Question 16

Triglyceride Structure :

Answer 16

Each triglyceride is composed of three fatty acid units attached to a glycerol unit.

Question 17

Glycogen :

Answer 17

A substance deposited in bodily tissues as a store of carbohydrates.

Question 18

Protein Molecules :

Answer 18

Are large complex molecules formed by one or more twisted and folded strands of amino acids.

Question 19

Amino Acids :

Answer 19

A simple organic compound containing a carboxyl and an amino group.

Question 20

Peptide Bonds:

Answer 20

A chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other. Releasing a molecule of water ( H2O )

Question 21

Double Helix :

Answer 21

Nucleotides that are arranged in a twisted, double strand.

Question 22

Structural Proteins :

Answer 22

Proteins that are generally fibrous and stringy .

Question 23

Functional Proteins :

Answer 23

Biological activity proteins.

Question 24

Enzymes:

Answer 24

A substance produced by a living organism which acts as a catalyst that significantly speed up the rate of virtually all of the chemical reactions that take place within cells

Question 25

Adenosine Triphosphate (ATP) :

Answer 25

Energy carrying molecule found in the cells of all living things .

Question 26

Adenosine Diphosphate ( ADP ) :

Answer 26

An important organic compound in metabolism and is essential to the flow of energy in living cells.

Question 27

Deoxyribonucleic Acid (DNA) :

Answer 27

A self replicating material which is present in nearly all living organisms.

Question 28

Ribonucleic Acid (RNA) :

Answer 28

A nucleic acid present in all living cells. Its role is to act as a messenger carrying instructions from DNA .
