AP Biology: Final Review

Maltose

Formed during digestion of starch

Chitin

Forms exoskeletons in the arthropods

Lactose

Milk sugar

Ribose

Sugar found in RNA

Starch

Polysaccharide used to store energy in plants

Sucrose

Disaccharide used to store energy in plants

Glycogen

Also called “animal starch”

Alpha Glucose

Monomer of starch

Galactose

Forms half of lactose

Beta Glucose

Monomer of cellulose

Cellulose

Forms components of cell walls

Deoxyribose

Sugar found in DNA

False

Isotopes of an element contain the same number of protons and different numbers of electrons

True

Electrons in different electron shells contain more energy if they are farther from the nucleus

False

A molecule must contain more than one atom of more than one element

True

Atoms can interact to give up, accept, or share electrons to produce a filled outer shell

True

Water moderates the temperature on earth because it can absorb and release large amounts of heat

True

Buffers are chemicals that can both take up and release H+, thus maintaining pH changes in a chemical system

Neutral charge, full outer energy level, or 8 electrons

How does an atom achieve the greatest level of stability?

What is a polar covalent bond such as is found in water?

How does hydrogen bonding occur due to the polar covalent bond in water?
