Unit 1

Question 1

Cohesion

Answer 1

When two of the same molecules form a hydrogen bond

Question 2

Adhesion

Answer 2

where two different surfaces or phases are attracted and stick together.

Question 3

Surface tension

Answer 3

the cohesive force at the surface of a liquid that allows it to resist external forces.

Question 4

capillary action

Answer 4

a combination of cohesion and adhesion that causes water molecules to have gravity move up/ against gravity

Question 5

Primary Structure

Answer 5

a straight chain of amino acids which is held together by peptide bonds

Question 6

Secondary structure

Answer 6

when the chain starts to coil or fold
The 2 shapes it can fold into are:
-Aphla Helix(spring)
-beta pleated sheet (folded paper)
-held together by hydrogen bonds

Question 7

Tertiary Structure

Answer 7

when it becomes a 3D shape because the R groups on the amino acids fold and connect together by hydrogen bonds, covalent bonds, and ionic bonds

Question 8

How many bonds does A and T have?

Answer 8

2

Question 9

How many bonds does G and C have?

Answer 9

3

Question 10

Purine

Answer 10

Double ring

Question 11

Pyrimidine

Answer 11

single ring for C,U,T

Question 12

Carbs

Answer 12

C,H,O

Question 13

Protein

Answer 13

C,H,O,N,S

Question 14

Nucleic Acids

Answer 14

C,H,O,N,P

Question 15

Lipids

Answer 15

C,H,O

Question 16

Hydrophillic

Answer 16

Polar (made up of lots of Oxygens, Sulfuers, and Nitrogens ) and folds towards the outside of a protein structure

Question 17

Hydrophobic

Answer 17

Non-polar (made up of Hydrogen and Carbon) and folds towards the inside of a protein structure

Question 18

what does Saturated fat looks like?

Answer 18

Looks like a straight line of a bunch of carbon in the middle that is surrounded by lots of Hydrogen

Question 19

what does unsaturated fat looks like?

Answer 19

Looks similar to saturated but at least has one double bond leading to the chain looking slanted at the end
