AP Biology Unit 1: Chemistry of Life Notes Pt. 1

Triacylglycerols

________ are highly concentrated stores of metabolic energy because they are reduced and anhydrous (without water)

Hydration shell

________: A three dimensional sphere of water molecules formed to break ions.

OH

What is at carbon 2 in RNA? Answer with a single words or term.

Dissociation

________: process where a compound or molecule breaks apart to form ions.

Electronegativity

What is the measure of the attraction of an atom for bonding electrons in molecules compared to that of other atoms? Answer with a single words or term.

Amino acids

________ are linked through peptide bonds to form polypeptide chains.

Van Der Waals forces

What are formed by interactions between charged molecules? Seen in gecko feet.

Cohesion

________ is the property of water that allows it to stick to itself.

DNA

________ has thymine.

RNA

________ has uracil.

Solvent

________: A substance that can dissolve other molecules and compounds

Solute

________: Molecules and compounds dissolved in a substance (solvent)

Solution

________: A homogeneous mixture of solvent and solute.

Disaccharide sugars

________ formed and broken down.

Cohesion

the property of water that allows it to stick to itself

Adhesion

the property of water that allows it to stick to substances that are either objects or surfaces other than itself

The 3 main elements

Carbon (C), Hydrogen (H), Oxygen (O)

Disaccharide sugars formed

Condensation reactions - a water molecule is released (dehydration)

Disaccharide sugars broken down

Hydrolysis reactions - a water molecules is added

Main components of symbolic triglyceride

Glycerol, Ester bond, Fatty acids
