SBI3U – Assigned Homework Thursday, March 11, 2009 – Answer Sheet Read Section 4.3, Protein Synthesis, pages 93 – 95. Understand the following terms: protein synthesis i: transcription messenger RNA ii: translation transfer RNA Label the following Figure: What term is given to the process occurring in the Figure to the right? View the following web pages: http://instruct1.cit.cornell.edu/Courses/biomi290/MOVIES/CENTRALDOG.HTML http://bass.bio.uci.edu/~hudel/bs99a/lecture20/lecture1_1.html Answer Section 4.3 Review – page 95: Understanding Concepts: 1, 2, 3, 4 Applying Inquiry/Communication Skills: 6 Read Section 4.4, Photosynthesis and Food Production, pages 95 – 97. Understand the following terms: photosynthesis Know the equation for (word and chemical) chlorophyll light-dependent reactions light-independent reactions What is essential for the light-dependent reactions? What is not essential for the light-independent reactions? State which reactions are labeled 1 and 2 and give reasons why you labeled the diagram the way you did: autotrophs heterotrophs chemautotrophs Answer Section 4.4 Review – page 97 and the questions that follow: Understanding Concepts: 1, 2, 3, 4 1: What do plants have the unique ability to do? Read Section 4.5, Cellular Respiration, pages 98 – 101. Understand the following terms: cellular respiration the total number of ATPs produced and from what steps glycolysis where in the cell this process takes place glucose – pyruvic acid aerobic cellular respiration where the majority of ATP is produced – name it anaerobic cellular respiration understand why this process occurs (i.e.: in humans) Label the following Figure: lactic acid lactic acid fermentation alcoholic fermentation Answer Section 4.5 Review – page 101 and the questions that follow: Understanding Concepts: 1, 2, 3, 4, 6, 7 1: Give the full name for ATP. What is ATP used for in the cell? What type of reactions are these? 2: When glucose is broken down, what type of reactions are these? 3: How many ATPs are produced when glucose is converted to pyruvic acid? What is not required in this step? Where in the cell does this step take place? 4: Where in the cell does the second step of cellular respiration take place? How many ATPs are produced in this step? 5: How come prokaryotic cells do not use aerobic (presence of oxygen) cellular respiration? 6: Write out the chemical equations for lactic acid fermentation and alcoholic fermentation. How many ATP are produced using lactic acid fermentation or alcoholic fermentation? How do these numbers compare to the number of ATPs produced using aerobic cellular respiration?
