Unit 1 Flashcards
Cohesion is when?
One water molecules bind with another water molecule
Adhesion is when?
One water molecule binds with another molecule that is not a water molecule
What is polarity
Unequal sharing of electrons between oxygen atom and hydrogen atom
Polar bonds?
When atoms with different electro negativities share electrons in a covalent bond
Does water have high heat capacity
Yes
Why does water have a high heat capacity?
Multiple hydrogen bonds between water makes it way harder for them to move around and raise the temperature of water. This is why it takes a lot of heat to change it.
Covalent bonds in water?
Bonds between the oxygen and the hydrogen in the same water molecule
What is the backbone for life
Carbob
Is carbon used is all biological macromolecules?
Yes
Nitrogen is in what macromolecules
Proteins and nucleus acids
Phosphorus is in?
Lipids and nucleic acids
What is dehydration synthesis
The removal of a water molecule and that results in a covalent bond between the two monomers
Hydrolosis?
Addition of water molecule breaking up a polymer into a monomer.
How is hydrolysis important?
It’s important in digestion, it breaks up polymers into monomers
How is everyone unique via nucleotides?
The way they are arranged
Structure determines?
Function
What is an example of a primary structure
A polypeptide
What is a polypeptide?
Short chain of amino acids which are linked by peptide bonds
A peptide bond is a?
Covalent bond
What two groups do amino acids have
Carboxyl and terminus group
Amino acids are?
Monomers of proteins
R groups can have either
Hydrophilic, hydrophobic and ionic substances
Function of the side group depends on what
The structure
How are dna and rna similar
Have the same structure of 5 carbon, phosphate group and a nitrogen base
