2. Shape defines function!!!!
There are millions of apartments in New York City, each having their own front door. When the mayor gives the “Key to the City” to a hero, does it mean that the hero can open every door in the city? Why, explain your answer.
Shape defines function!!!!

3. Day 7 AIM: The Chemistry of Life- Proteins & Nucleic Acids

4. O C H N 1) What are proteins?
1) A protein is a huge (macro) organic molecule that is made of carbon, hydrogen, oxygen, and nitrogen. O C H N

5. 2) Where can we find Proteins?
2) Proteins can be found in feathers, fingernails, hair and muscle.

6. 3) What are proteins made of?
3) Proteins are huge 3 dimensional molecules composed of amino acids.

7. 4) What are amino acids?
4) Amino acids are the subunits of proteins. There are 20 common amino acids.
These amino acids link together by a special bond called a peptide bond.
These amino acids combine with each other in many different combinations. The order determines what type of protein the molecule is.

9. 5) Why are proteins important?
5) Proteins provide three major functions
Structure- Proteins could be strong fibers that give support.
b) Enzymes- Special molecules that speed up chemical reactions.
c) Communicate signals within cells and between cells. Hormones & Neurotransmitters

10. 6) How does a protein get its shape?
Protein structure is based on the order in which the amino acids link together. Temperature and pH affects the structure, shape and function of proteins

11. AIM: The Chemistry of Life- Nucleic Acids

12. What is a Nucleic Acid?
Nucleic Acids is a humongous molecule that is made of nucleic base (also known as nucleotides).
There are 5 types of nucleotides
Adenine
Guanine
Cytosine
Thymine
Uracil

13. Why are Nucleic Acids important?
Nucleic Acids store information to make other molecules.
This information is past down from a parent or parents to an individual.
These “packets of information” are stored in genes.

14. Where do we find Nucleic Acids?
The most common forms of nucleic acids are:
DNA
RNA
