Describe a hydrolysis reaction.
When water will come in and break a bond between two monomers.
Why does ice float?
The water will expand as it freezes, making ice less dense so it can float.
If we change one amino acid in a chain what is the result to function of that protein?

What two properties of water allow water to move up a tree from the roots?
Adhesion: Water bonding to other molecules
Describe the reaction to combine polypeptides together.
Water is removed and a peptide bond is formed.
When we put phospholipids in water what does it do?

What is the sugar found in DNA and RNA
DNA: Deoxyribose
RNA: Ribose
Why do cows need bacteria in their stomach?
To be allow them to break down cellulose so they can use the glucose molecules
How do hydrogen bonds form between water molecules?
The negative charge in an oxygen atom is attracted to the positive charge in a hydrogen atom
