About This Chapter
OAE - Integrated Science: Biomolecules & Enzymes - Chapter Summary
This chapter explores the structures, functions, and characteristics of various biomolecules and enzymes. These molecules include lipids, amino acids, DNA, and more. There are four lessons discussing proteins, four on DNA, and finally four more on the function of enzymes. Study the lessons in preparation for the OAE Integrated Science exam. By the end of the chapter, you will have reviewed:
- Lipids: structure and function
- Peptide bonds, amino acids, polymerization
- The primary, secondary, tertiary, and quaternary structure of proteins
- The nucleobases of DNA
- The double helix structure of DNA
- RNA versus DNA
- Types of RNA
- Substrate, active site, and activation energy of enzymes
- Environmental effects of enzymes
- Prosthetic groups, coenzymes, and cofactors
- Enzymatic reactions
The end of each lesson will have a quiz you can use to check your comprehension. These quizzes are written in the same way as the questions on the OAE Integrated Science exam. By giving yourself a small amount of time to answer each of these questions, you can effectively simulate your upcoming exam.
OAE - Integrated Science: Biomolecules & Enzymes Chapter Objectives
The OAE Integrated Science exam has four tested domains: earth and space science, life science, physical science, and the nature of science. This chapter can prepare you for some questions in the life science domain which will have about 25% of the exam's 150 multiple-choice questions. The test is only 180 minutes long and it is also computer based.
1. Structure and Function of Lipids
Molecules called lipids have long hydrocarbon chains that determine the way they act. They can be fats, oils, or hormones, and even exist in our cell membranes. Learn more about the chemical structure and biological function of various lipids in this lesson.
2. Proteins I: Structure and Function
We need our proteins, not just as a major food group but for the many useful roles that they play in our bodies. In our introductory lesson to proteins, you'll learn about the many functions we rely on them to perform.
3. Proteins II: Amino Acids, Polymerization and Peptide Bonds
In this lesson, we'll take a deeper look at amino acids. You'll learn what makes a peptide, and what separates a protein from other kinds of amino acid bonds.
4. Proteins III: Structure and Characteristics of the 20 Amino Acids
How do amino acids form the intricate polypeptide chains found in proteins? It's a matter of chemistry. Join glycine, a special amino acid, as she sizes up the other amino acids.
5. Proteins IV: Primary, Secondary, Tertiary and Quaternary Structure
How is progressing through higher order protein structures like crafting an essay? In this lesson, you'll explore everything from quaternary structures to denaturation as we show how the different structures are intertwined.
6. DNA: Chemical Structure of Nucleic Acids & Phosphodiester Bonds
In this lesson, you'll discover what nucleotides look like and how they come together to form polynucleotides. We'll also explore nucleic acids and focus on DNA in particular.
7. DNA: Adenine, Guanine, Cytosine, Thymine & Complementary Base Pairing
Learn the language of nucleotides as we look at the nitrogenous bases adenine, guanine, cytosine and thymine. Armed with this knowledge, you'll also see why DNA strands must run in opposite directions.
8. DNA: Discovery, Facts, Structure & Function in Heredity
This lesson will help you to navigate the twists and turns of DNA's structure. We'll also clue you in on the amazing discoveries that put this nucleic acid in the limelight as the molecule of heredity.
9. Differences Between RNA and DNA & Types of RNA (mRNA, tRNA & rRNA)
In this lesson, you'll explore RNA structure and learn the central dogma of molecular biology. Along the way, you'll meet the three types of RNA and see how the cell uses them most effectively.
10. Function of Enzymes: Substrate, Active Site & Activation Energy
In this lesson, we'll learn how enzymes function to lower the activation energy of a chemical reaction. Enzymes bind to their substrates to perform all kinds of important and essential cellular processes, as well as processes that help you enjoy a slice of pizza!
11. Enzyme Activity & Inhibition: Structure, Substrates, pH & Temperature
Enzymes appreciate the right working conditions. Can you blame them? We all work best in the correct environment. In this lesson, we'll learn how substrate concentration, temperature, and pH affect enzyme activity and structure.
12. Coenzymes, Cofactors & Prosthetic Groups: Function and Interactions
Some enzymes require helpers to recognize a substrate or complete a reaction. These helpers include cofactors, coenzymes, and prosthetic groups, which are required for some enzymes' functions.
13. Enzymatic Reactions: Inhibition and Regulation
Enzymes are generally not allowed to run uncontrolled in a cell. While they are useful in catalyzing reactions, there is a time and place for everything. In this lesson, we'll discuss enzyme activators and inhibitors that regulate these reactions positively and negatively, respectively.
