Ph scale and types of macromolecules

Question 1

Acid

Answer 1

A substance that has increased hydrogen ions

Question 2

Base

Answer 2

Provides hydroxide ions (OH-) or other negatively charged ions that combine with hydrogen ions, reducing their concentration.

Question 3

PH scale

Answer 3

<7 = acidic 
>7= alkaline

Increased hydrogen = decreased pH
Decreased hydrogen = increased pH

Question 4

Types of macromolecules

Answer 4

Lipids, nucleic acids (DNA/RNA), proteins, carbohydrates

All contain carbon

Question 5

Monomers

Answer 5

Building blocks. They organize into polymers using covalent bonds

Question 6

Polymer

Answer 6

3+ monomers

Question 7

Polymerization

Answer 7

Making polymers out of monomers. Dehydration synthesis (get rid of H2O when bonding) anabolic
