**Exam 2 Study Guide** 50 multiple choice questions You do NOT need to memorize amino acids, I will give you codons and their corresponding amino acids Chapter 5 -Understand the central dogma (DNA -- RNA - Protein) (AGCT -- AGCU -- Amino acids) -Know the products of transcription that get turned into the starting pieces for translation -What is a protein conformation and [what are the 4 levels of protein structure] -What is a codon? Anti-codon? -Given a DNA strand, know how to convert to RNA, and then to amino acid -Know basic steps of translation -What does ribosome do -What are the different sites on the ribosome -What is a tRNA -What is an amino acyl tRNA synthetase -What is produced during translation -What are start and stop codons? Chapter 6 -What is a catabolic reaction? Anabolic? -What is an exergonic reaction? Endergonic? -Understand the concept of free energy. What happens to free energy in an exer/endergonic reaction? -What do enzymes do to a reaction? What do they do in terms of free energy? -Know the structures and bonds in ATP -Know laws of thermodynamics -Know the different types of inhibitors? Chapter 7 -What is an autotroph? Heterotroph? -What are the steps of cellular respiration? -Know the starting reactants and final products of EACH step -Know whether each step is substrate level, oxidative phosphorylation, or none -Know the important intermediates or byproducts of each step (that we discussed in depth) -Know where each step occurs -Know whether oxygen is needed at each step -How does the electron transport chain work? What does oxygen do? -What happens to respiration if oxygen is NOT present? -Can we use things other than glucose for metabolism? Chapter 8 -What are starting reactants and products of photosynthesis? -Know the different steps of photosynthesis (light reactions vs calvin cycle) -Where do they occur -What are the main steps -What are the reactants and products of each step, and MAJOR enzymes -What is chlorophyll? What type of light does it use? What does it do during the light reactions? -What is produced in the light reaction? The dark reaction?
