300
What is the function of Nucleic Acids?
Store and transmit hereditary, or genetic, information
300
What is another name for substrate.
Reactants
300
What are the charges on a water molecule, and what does this make the overall net charge?
Oxygen is negative and hydrogens are positive. This makes the water molecule neutral.
400
What is the name for the bonds that bond water molecules to each other and why are they attracted to each other?
Hydrogen bonding and they are polar which means that they have charged molecules. So positive attracts to negative and negative attracts to positive.

What is another name for the image shown below?
In addition how would we break these two molecules apart?
1. Disaccharide
2. adding water by the process of hydrolysis
400

When looking at this image what is the fatty acid chains and what is the glycerol?
400
Label each section of this nucleotide.
400
How does enzyme concentraion affect enzyme activity?
As enzyme concentration increases so will the enzyme activity until all substrates are used. When all substrates are used the enzyme activity will stay at a constant.
