4. RRNA
5. MRNA
10. What is the bond that Glycosidic linkages
links monosaccharides?
11. What is the structure of Linear or branched chains, may be cross-linked (1)
carbohydrates?
12. What is the function of Energy storage, structure, cell identity
carbohydrates?
13. What are examples of 1. Cellulose
carbohydrates? 2. Chitin
3. Starch
4. Glycogen
14. What is the structure of Mostly linear, hydrophobic
lipids?
15. What are the functions Energy storage, signaling, form membranes
of lipids?
16. What are examples of 1. Steroids
lipids? 2. Fats
3. Phospholipids
17. What is the difference Non polar- have equal sharing of electrons
between non polar co- Polar- have partial charge
valent, polar covalent Ionic- transfer of electrons
and ionic bonds?
They are related based on their electronegativity differences
18. Non polar covalent bonds have the highest potential energy

Which bond has most
potential energy: non
polar covalent, polar co-
valent or ionic bonds?
19. More pull of a bond Less energy
means more or less en-
ergy?
20. Which has more ener- Lipids have more energy because they have more C-H bonds instead of
gy? Lipids or carbohy- C-O bonds (carbs)—> non polar
drates and why?
C-H bond—> has more potential energy
21. Why are weak bonds Weak bonds are crucial because interactions are transient. They are
crucial? more efficient because it takes less energy to break (faster reactions and
bonds can be broken easily).
In DNA replication hydrogen bonds can be broken. They have many
weak bonds instead of 1 strong bond which makes the helix stable (even
tho the bonds are weak). The weak bonds also give it flexibility.
22. What are the 4 types of 1. Ionic bonds
non-covalent bonds? 2. Hydrogen bonds
3. Van der waals
4. Hydrophobic interactions
23. Water can disrupt hy- Bonds break and reform constantly. There is also strength in num-
drogen bonds. Why bers—> all bonds don't break and reform at the same time. They go

or other molecules in
aqueous solution?
