Biomolecules Summary Notes     

Review Questions and Their Answers 

DNA LESSON

 

We will explore the nature of DNA. We will review these notes here  and later you will get a worksheet looking at DNA replication.

Observing biomolecules in action

 Observe a cooking demonstration and note ALL the biomolecules in the ingredients.  Take photographs of the ingredient , the recipe and the outcome.  Did the biomolecules undergo any changes due to changes in  thermal energy? pH?  What was their state ? solid or liquid ?  Did anything turn into a gas?

Demonstrate your biochemical knowledge by explaining what happened to the biomolecules.  Your report may be in the form of a document, pdf, powerpoint (powerpoint is preferred)

Your report includes

a Title:  What was the food that was prepared?

1. A table with the following titles:  ingredient, biomolecule, draw the formula

2.  Steps to make the food:  Describe changes in thermal energy and pH if any

3.  Conclusion:  write a short paragraph summarizing what you learned/tasted 

Evaluation /30

27-30.  This is an excellent and complete analysis of all the biomolecules, the report is organized and includes pictures, either drawings or photos. it has excellent presentation 

20-25.  This is a complete analysis of all the biomolecules. the report includes pictures or drawings of most biomolecules

15-20. This is a partial list of all the biomolecules. the report contains no pictures or drawings

0-15. This report is a good start but it is not complete 

Sept 8 to 16, 2025 : Biomolecules.

 lecture on biomolecules here:  Please review the notes on Carbohydrates and Proteins

Biomolecules Notes  

And here are some summary notes reviewing the same content describing the monomers and polymers that can form through dehydration synthesis and hydrolysis . your teacher will review these concepts over a few days

Biomolecules Summary Notes     

After reading these notes, work on this worksheet on biomolecules . The answers to these questions begin on page 8 of the Biomoledules Summary Notes in the chapter called  BIOCHEMISTRY AND CELL COMPOUNDS

We will spend a few days on this important topic and then you will get a test. 

At the end of this unit you can do these review questions .  Our test will include these questions

Review Questions and Their Answers 

in addition, i mentioned in class that you ought to be able to

1. draw each kind of monomer: an amino acid, a monosaccharide, a nucleotide.  Draw an example of an amino acid (glutamate)

2. draw the hydrolysis and dehydration synthesis of monomers , like amino acids making a peptide bond

3.  identify different kinds of biomolecules if you see them 

Memory tricks to remember hydrolysis and dehydration synthesis.  I gave you new lyrics for this abba song.
