BIO101 - Straighterline Test 2 Questions and Answers Rated A+ when two glucose molecules combine they form a disaccharide molecule and a water molecule which of the following statements is NOT true of chemical bonds? salts are covalently bonded Which nutrient source is the easiest one for humans to break down and form ATP? glucose the water strider is an insect that skates across the water without sinking. The tips of its feet must be coated in molecules that are hydrophobic DNA codes for the sequence of amino acids in the primary structure of protein, but not for sugars or lipids. This is because proteins are the main structural and functional components of cells. the backbone of a nucleic acid strand is composed of alternating pentose sugars and phosphate groups which of the following reactions is most likely to occur is an individual was to ingest a large dose of lemon juice There would be an increase in the amount of carbonic acid with in the bloodstream. If the carbonic acid didn't form, then the pH of the individual blood could shift toward 7.2. In the search to discover the agents that cause mad cow disease, scrapie in sheep, and CJD and kuru in humans, diseased brain tissues were passed through a fine filter to remove bacteria. The filtrate was still infectious, indicating that something smaller than bacteria, either viruses or organic molecules, must be the causative agent. If a virus was responsible for these brain diseases, then the infectious agent would contain either RNA or DNA. Other possibilities were that the agent was a carbohydrate, fat, or protein. Tissue filtrates were treated with agents that destroyed just one of these chemicals and then injected into a healthy animal, with the results as follows. What is the infectious agent? protein a piece of meat and a piece of fruit are fed to both a lizard and a person. the extent to which these foods are digested by digestive enzymes along these two gastrointestinal tracts varies. which of the following is not a reason for the variation in digestion? the amount of protein in the meat and fruit. which science cannot describe "thinking" in physical terms, we are certain that the process involves metabolism inside brain cells. With positron emission tomography (PET scan), it is possible to inject short-lived isotopes and image the regions of the brain that have the most active metabolism during various mental activities. However, the cellular energy expended in thinking must be less than the chemical bond energy supplied in food to these brain cells. the change in free energy of a reaction, delta G, is calculated by subtracting the free energy content of the reactants from that of the products. where within the cell is atp built up mitochondria which of the following is a by-product of photosynthesis oxygen the atp synthase complex is located in the cristae of the mitochondria the final products of glycolysis are 2 pyruvate, 2 ATP, 2 NADH + N(+) which of the following statements about fermentation is not true? fermentation involved the citric acid cycle. which of the following is a substrate of cellular respiration glucose which of the following statements about glycolysis is the glycolysis breaks glucose down to two pyruvate molecules. which of the following is not a consequence of the lactate that results from fermentation in the muscles it is stored in muscle cells for later atp production what will cycle the energized electrons from the reaction center of the PS1 back to the reaction center in PS1 cyclic electron pathway which of the following statements comparing the ATP synthase complex in cellular respiration and photosynthesis is not the both require the movement of H(+) from inside a compartment to outside of the compartment what are the two sets of reactions for photosynthesis? light reactions, Calvin cycle reactions why does the chloroplast utilize a cyclic electron pathway as well as the noncyclic electron pathway? the calvin cycle ultilizes more ATP than NADPH and the cyclic electron pathway produces ATP which of the following is a substrate in the photosynthesis equation? CO2 which cofactor is involved in the Calvin cycle
