2.3 Chemical Reactions

Question 1

Chemical energy

Answer 1

potential energy that is stored in the bonds of compounds and molecules

Question 2

What is Conversion of energy

Answer 2

from one form to another generally releases heat, some of which is used to maintain normal body temperature.

Question 3

What are Catalyst

Answer 3

speed up chemical reactions by lowering the activation energy needed for a reaction to occur

Question 4

Catalyst Fun Fact?

Answer 4

Rather, it lowers the amount of energy needed to start the reaction.

Question 5

Can a Catalyst really make molecules hit a exact spots.

Yes

Answer 5

A catalyst helps to properly orient the colliding particles. Thus, they interact at the spots that make the reaction happen.

Question 6

Are Anabolism Usually Endergonic or Exergonic

Answer 6

Energonic, endergonic because they absorb more energy than they release.

Question 7

Are Catabolism usually Exergonic or Endergonic.

Answer 7

exergonic because they release more energy than they absorb.

Question 8

Why are oxidation–reduction reactions important?

Answer 8

they are the reactions that break down food molecules to produce energy.

Question 9

Inorganic compounds

Answer 9

-usually lack carbon and are structurally simple.

-Their molecules also have only a few atoms and cannot be used by cells to perform complicated biological functions

-They include water and many salts, acids, and bases

-contain carbon include carbon dioxide (CO2), bicarbonate ion (HCO3−), and carbonic acid (H2CO3).

Question 10

Organic compounds always contain??

Answer 10

Always contain carbon, usually contain hydrogen, and always have covalent bonds.

Most are large molecules, many made up of long carbon atom chains. Organic compounds make up the remaining 38–43% of the human body.

Question 11

True or False

Organic Compounds always contain Ionic Bonds?

Answer 11

False:

They always contain Covalent.

Question 12

Non-Polar
Polar

Inorganic
Organic

Hydrophobic
Hydrophilic

Question 13

What is Hydrolysis reactions? enable dietary nutrients to be absorbed into the body.

Answer 13

enable dietary nutrients to be absorbed into the body.
-Loss of water

Question 14

dehydration synthesis reaction

Answer 14

a water molecule is one of the products formed. As you will see later in the chapter, such reactions occur during synthesis of proteins and other large molecules .

Question 15

Molecules that have the same molecular formula but different structures are called

Answer 15

Isomers
