BIO Lecture Exam 1 Review Chapter 1: What is the difference between qualitative and quantitative? What is the difference between scientific law and scientific theory? What are scientific laws often expressed as? What were the 6 properties of life mentioned during lecture? Know examples of each property. In what from does energy enter an ecosystem? In what form does it exit? Name the 3 major domains of life. Which one is different from the other two, why? What is one important thing a hypothesis MUST be? Chapter 2: What is an element? What are the subatomic particles? What subatomic particles make up an atom’s nucleus? What does the atomic number tell you about an atom? What is an isotope? What are valence electrons and what do they tell us about an atom? What are ionic bonds? When ionic bonds occur, the result are charged particles, what is the term referred to these particles? What is the term to describe a positively charged particle? How about a negatively charged particle? What is a covalent bond? Determine the difference between a polar covalent & a nonpolar covalent bond. What is electronegativity? What is hydrophobic and hydrophilic mean? What type of molecule is water (polar or nonpolar)? Why? What are the properties of water that were discussed in class? Be able to differentiate between them & give examples. What is an acid? What is a base? In an acidic solution what ion concentration is the lowest? Why can carbon form such large molecules? When referring to Carbon, what is tetravalence? What are hydrocarbons?Are they polar/nonpolar? What are isomers? Name & describe the 3 types of isomers. Name the 7 functional groups & know their molecular formula. Chapter 3: What are the 4 major macromolecules? Which is different from the other 3? Why? What is a polymer? What is a monomer? Know the difference between a dehydration synthesis reaction and hydrolysis. What is the purpose of most carbohydrates? What is the process that links disaccharides into polysaccharides? Held together by what bonds? What type of molecule do plants store their energy? How about animals; where in the body can we find these molecules? Lipids are considered hydrophilic. True or False? Lipids have little to no affinity for water. True or False? Why are lipids considered nonpolar? What biological function do lipids have when referring to cells? What do fats consist of (2 things)? What does a triglyceride consist of & through what bond are they joined? What is the difference between a saturated & unsaturated fat? Hydrogenation coverts saturated fats into unsaturated fats, True or False? Unsaturated fats are liquid at room temperature, True or False? What does a phospholipid consist of? In a phospholipid, know which regions are hydrophobic and hydrophilic. Why do polar molecules have such a difficult time passing the cell membrane? What are the monomers of proteins? What type of bond connects these monomers? Briefly describe the 4 levels of protein structure. What is denaturation? What are the 2 types of nucleic acids? What does a nucleotide consist of? Through what bond are nucleotide polymers joined? Chapter 4: Explain why cells are relatively small. Give the features that are included inALL cells. Explain the differences between prokaryotes & eukaryotes. What is a ribosome’s function? List the components of the Endomembrane system. List all ORGANELLES & their functions involved in the Endomembrane System. What are vesicles? Describe the process of phagocytosis. Mitochondria & chloroplasts are part of the endomembrane system, True or False? Describe what a cell’s cytoskeleton is & its role. What are the 3 types of fibers that make up the cytoskeleton? Give their individual functions. Briefly explain the endosymbiotic theory What 2 reasons are there that support this theory? What is the purpose of intercellular junctions? Name them. What are chloroplasts?
