CBIO 111-01 and 02 Spring 2018 Final 3 of metabolism are pathways that A build complex molecules froe input in the form of ATP is needed in which of the 13, release stored chemical enery 2. elassitying organisms according to their source of energy and carbon, how would you classify humans are organisms that derive energy from sunlight A. Phototrophs B. Autotrophs Which of the following organisms are considered heterotrophs? A. most bacteria B. dogs E.most bacteria and dogs C. plants D. hydrogen bacteria 6. The potential energy in a molecule of ATP that is harmessed to do the work of the cell is held in part in the A. carbon-carbon bonds of the sugar B. repulsion of the phosphate groups from each other C. the carbon-nitrogen bonds of the base. D. the carbon-oxygen bonds of the sugar 7. Some examples of work that a cell has to do: 8. In general ATP isconsumed in and produced in 9. Imagine that a bowling ball is placed at various locations along a staircase. At which location does the ball A. Synthesizing DNA, RNA, proteins B.Moving vesicles in a cell c. Pumping substances across membranes D. All of the above E. None of the above A. anabolic, catabolic b. catabolic, anabolic possess the greatest amount of potential energy? A. at the top of the stairs B. at the bottom of the stairs C. in the middle of the stairease D. The ball will have the same amount of potential energy no matter where it is placed. 10. Which one of the following is the most common energy "currency" for a cell? A. ATP B. DNA C, glucose D. protein E, NADH 11. Entropy is often increased by: A. heat. B. order.?. potential energy. D. kinetic energy. 12. Reactions in which there is a negative change in free energy (-AG) are: B. spontaneous and exergonic. D. nonspontaneous and exergonic. A. spontaneous and endergonic. C. nonspontaneous and endergonic. 13. Which of the following reactions is most likely to be exergonic? A. the synthesis of a phospholipid from glycerol and fatty acids B. the replication of DNA from free nucleotides C. the formation of cellulose from individual glucose molecules D. the digestion of protein from food into amino acids 14. Which of the following type(s) of inhibitor can bind to the active site of an enzyme? A. a competitive inhibitor B. an allosteric inhibitor C. all types of inhibitors 15. What are examples of potential energy? B. Wind, sunlight, heat Wind, water evaporation, gasoline. C. candy bar water behind a dam, cloud A. D. Sunlight cloud, cooked potato 6. The approximate yield of ATP molecules from the full oxidation of a molecule of glucose is: E. 64 C. 12. D. 32Explanation / Answer
Answer 1. Option a
In anabolism, many simple molecules combine to form a complex molecule. Eg- photosynthesis. In this carbon dioxide and water unite energy is given by sunlight and starch is synthesised.
Answer 2. Option a
In catabolism, larger molecule breaks to form the smaller molecule. Eg- Respiration in which glucose breaks utilising the ATP and in the end converts to carbon dioxide and water.
Answer 3. Option d
We cannot prepare our own food dependent upon others means heterotrophs and utilise the chemical energy thus chemo+ heterotrophs = chemoheterotrophs.
Answer 4. Option a
Phototrophs are the organisms that can prepare their own food utilising sun light. There are a part of autotrophs. Chemoautotrophs utilise chemicals to synthesise energy.
Answer 5. Option e
Heterotrophs cannot prepare their own food like dogs. Most bacteria are also chemoheterotrophs they utilise the energy of the chemicals to sustain life.
Answer 6. Option b
Because ATP hydrolysed to ADP and gives energy. ADP hydrolysed to form AMP and energy is produced.
Answer 7. Option d
As per central dogma of biology, DNA synthesises RNA by transcription, RNA synthesises proteins by translation.
Vesicles are formed by golgi body during the Post translation modification.
Transmembrane proteins helps in passing proteins across the plasma membrane.
Answer 8. Option b
Eg in Respiration ATP is consumed.In anabolism like photosynthesis ATP is produced.
Answer 9. Option d
Potential energy refers to the energy at rest irrespective of the place.
Answer 10. Option a
ATP stands for adenosine triphosphate. Our body utilises energy in the form of ATP.
Answer 11. Option d
Entropy is a degree of randomness more kinetic energy means more movement means more entropy.
Answer 12. Option b
Spontaneous means will proceed on its own and release the energy thus exergonic.
Answer 13. Option d
Because protein digestion will lead to energy release.
Answer 14. Option a
Allosteric inhibitor binds at a site other than the active site.
Answer 15. Option c
Because these are at rest and energy at rest is the potential energy.
Answer 16. Option d
However exact is 36
Glycolsis 6 ATP
Oxidative phosphorylation 6 ATP
Kreb cycle 24 ATP
Total 36 ATP
