13. Which statement is true about cellular respiration? A) You cannot obtain energy (ATP) from fat as the energy expenditure is too much B) You cannot obtain energy (ATP) from protein because of the energy expenditure C) You can obtain energy from both proteins and fat even though the initial energy D) E) expenditure is much A, B, and C are all true statements Neither A, B nor C is correct statement 14. Adenosine Triphosphate (ATP) is a transformed form of sun's energy fueling cellular work A) This statement is false as ATP is not ultimately derived from sun B) This statement is true as all energy form in our solar system is derived from sun C) ATP is generated from carbohydrates and the sun has nothing to do with it. D) I am a little confused by this question and answer choices 15. The breaking apart of water in photosynthesis is critical to animals because it produces what: A) Generates ATP B) Regenerates RuBP C) Creates a food source. D) Consumes carbon dioxide E) Oxygen. 16. When glucose is the fuel source, what is the correct sequence of stages in cellular respiration? A) B) C) D) E) Krebs cycle, electron transport, glycolysis Electron transport, Krebs cycle, glycolysis Krebs cycle, glycolysis, electron transport Electron transport, glycolysis, Krebs cycle Glycolysis, Krebs cycle, electron transport 17. The three main products of glycolysis are (not reviewed): A) ATP, NAD+, and CO2 B) ATP, pyruvic acid, and CO2. C) ATP, NADH, and Pyruvate. D) ATP and pyruvic acid. 18. Glycolysis occurs in the cell's A) Plasma membrane. B) Mitochondria. C) Golgi apparatus. D) Cytosol. E) Nucleus.Explanation / Answer
13. C. We can obtain energy from both proteins and fats even though the initial energy expenditure is much.
14. B. The statement is true as all energy forms in our solar system is derived from sun. The process of photosynthesis consists of various steps in which solar energy is used in photolysis which promotes to proton gradients and formation of ATP.
15. E. The process of photolysis produces oxygen which is immensely important for the survival of animals and humans on Earth.
16. E. Glycolysis- Krebs cycle- Electron transport. Glucose is first converted to pyruvic acid through glycolysis and then enters Krebs cycle where ATP and NADPH are produced and ultimately the electrons are used to synthesize large amount of ATP in ETS.
17. C.Three main products of glycolysis- ATP, NADH and pyruvate.
18. D. Glycolysis occurs in cell's cytosol.
