WHAT SHOULD I KNOW FOR THE TEST INTRO TO BIOLOGY-Chapters 1 & 2 Review: SLIDE SHOW PACKETS VOCAB list Starts with ? Chapter ?”s MACROMOLECULE HANDOUT CHARACTERISTICS OF LIVING THINGS: What is BIOLOGY? What are the 8 Characteristics of Living things? What is an autotroph? What is a heterotroph? What does unicellular and multicellular mean? Be able to give examples of these. What is the difference between sexual and asexual reproduction? What is homeostasis? Why is maintaining homeostasis important for living things? What is metabolism? What is differentiation? What is evolution? What are stem cells? What happens to embryonic cells as they grow and develop? A LITTLE CHEMISTRY/ENZYMES What is an ion? Which atom is special to living things because it can join 4 other atoms at the same time? What atoms are important to living things? Be able to give the symbol for these (carbon= C, oxygen, hydrogen, nitrogen, phosphorus, sulfur) Which ions are important to living things? Be able to give the symbol for these (sodium= Na+, potassium, calcium, chloride, hydrogen). What are polar and non-polar molecules? Give examples. Which parts of a phospholipid molecule are polar? Which parts are Non-polar? What are hydrophobic and hydrophilic molecules and how do they act? What are Hydrogen bonds? How de you write a chemical equation? What are reactants? What are Products? What happens in a HYDROLYSIS reaction? What happens in a DEHYDRATION SYNTHESIS reaction? What is a catalyst? What molecules act as catalysts in living things? (Be able to identify the parts of an enzyme reaction in a picture.) What is an active site? What is a substrate? What is an enzyme-substrate complex? What is denaturing? What environmental factors can cause enzymes to denature? BIOMOLECULES Which 4 MACROMOLECULES are important to living things? (carbohydrates, lipids, proteins, and nucleic acids) What subunits are used to make these? Be able to ID these in a picture and give examples. Explain the difference between mono and polysaccharides. Be able to give examples of these. Be able to name the 3 polysaccharides and tell what they do. What are the 5 nitrogen bases used to make nucleotides? Which ones make DNA? Which ones make RNA? How is DNA different from RNA? In a DNA molecule which nitrogen bases always bond with each other? Be able to ID the following in a picture: DNA, RNA, ATP, amino acid, nucleotide, phospholipid, glucose Which macromolecules are important in making cell membranes? Which molecules help in transport? Which molecules carry information? Which molecules act as enzymes? What does INSULIN do? What does HEMOGLOBIN do? What does ATP do? What does glucose do? What does DNA do? What does RNA do?
