Spring 2008 By Dr Balko 1. How were the carbon atoms on Earth synthesized? 3.1 Carbon atoms found on earth were synthesized: 1) by the breakdown of water in lakes 2) during the first second of the big bang 3) by photosynthesis 4) in the interior of stars and we are all formed from stardust 5) by respiration 2. Why are proteins better catalysts than RNA? 3.2 Proteins are better catalysts than RNA because 1) RNA contains more phosphate than proteins 2) RNA is acidic 3) Proteins contain nitrogen 4) there is more diversity in the nucleotides than in the amino acids 5) there is more diversity in the amino acids than in the nucleotides 3. Why is the cell considered the basic unit of life because? 4.1 In 1665, Robert Hooke, the discoverer of cells, called the individual units in a tissue of cork cells because: 1) They were filled with protoplasm. 2) They contained a nucleus. 3) They were as empty as a monk’s apartment. 4) They were the basic unit of life. 5) They were spherical. 1.1 The cell is the basic unit of life because 1) it is midway between the biosphere and an organic molecule in size 2) it is the smallest unit capable of exhibiting the fundamental characteristics of life 3) it was discovered by Robert Hooke in 1665 4) it contains the nucleus 5) Dutrochet, Schleiden and Schwann said so more than a hundred years ago 4. What portion of the cell membrane forms the major barrier to the movement of ATP, sugar and proteins? 4.9 ________form the major barrier to the movement of ATP, sugar and proteins across membranes: 1) Proteins 2) Carbohydrates 3) Nutrients 4) Lipids 5) Salts 5. Within which organelle is Carbon dioxide and water are combined to make carbohydrate? 1

Spring 2008 By Dr Balko 4.4 Carbon dioxide and water are combined to make carbohydrate in the: 1) Chloroplast 2) Nucleus 3) Mitochondria 4) Endoplasmic Reticulum 5) Golgi Apparatus 6. What is the summary equation for cell respiration? 10.5 C(H 2 O) + O 2 CO 2 + H 2 O + energy is the summary formula for 1) The Krebs cycle 2) The Calvin cycle 3) Glycolysis 4) Photosynthesis 5) Respiration 7. How would you estimate the volume of blood through the human heart if you are given the volume pumped per beat and the number of heart beats per minute? 2.6 Estimate the volume of blood pumped through the heart in a day using dimensional analysis assuming the volume of blood pumped through the heart in one beat is 100 ml. The heart beats 60 times/minute, there are 60 minutes in an hour and 24 hours in a day. There are 1000 ml in a liter. 1) 144 liters/day 2) 8640,000 liters/day 3) 8640 liters/day 4) 8.64 liters/day 5) 360 liters/day 2.7 Set up an algebraic equation that can be used to estimate the volume of blood in liters pumped through the heart in a day using dimensional analysis. Assumes the volume of blood pumped through the heart in one beat is 100 ml. the heart beats 60 times/minute, there are 60 minutes in an hour, 24 hours in a day and 1000 ml in a liter.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
