Consider ten glucose molecules that enter a cell. How many ATP can be generated by the complete catabolism of these into CO2 and H2O? If all ten are first incorporated into glycogen, liberated from glycogen, and then fully catabolized into CO2 and H2O, does the ATP tally increase, decrease or stay the same? Consider that 1 UTP = 1 ATP. Explain. Describe the processes which produce ATP and provide a balanced equation of glucose, CO2, H2O and O2

- Trans-fatty acids are synthetic forms of fatty acids made from altered unsaturated fatty acids. Trans-fatty acids are denser, solid at room temperature, and store more energy in the same unit of volume than unsaturated fatty acids. The production of trans-fatty acids involves the reorientation of one of the hydrogen atoms attached to a double-bonded car- bon atom, as illustrated in the figure below. unsaturated fatty acid OHHHHH HOC CCCC-c II I I HHHH trans-fatty acid |||| Molecular model of an unsaturated and trans-fatty acid Based on the structures shown above, H -C-C-C-C-C-H HHHHH TTTTT !!!!!

Why don’t we just accumulate free monosaccharides inside the cells? What is the difference between dietary? Insoluble and soluble fiber? Cite examples of these fibers to justify your answer. Raffinose, stachyose, and verbascose are types of oligosaccharides but are described to be prebiotics. Describe the structure of the three and how they act as prebiotics in the diet. How does the structure and monomer composition affect the degree of digestion and absorption of carbohydrates?arrow_forwardGlucose is phosphorylated to glucose-6-phosphate by hexokinase in the first step of the glycolytic pathway to trap it in the cell, as G6P cannot diffuse across the lipid bilayer. This reaction also decreases the concentration of free glucose, favoring additional import of the molecule. However, this has a postive standard free energy of 3 kcal per mole. To favor this reaction, hydrolysis of ATP is coupled, which has a standard free energy of -7 kcal per mole. Determine the actual free energy change in kcal/mole for the following conditions: Glucose concentration: 4.5 mM ATP conc: 3.79 mM G6P conc. 0.052 mM ADP conc: 0.12 mM inorganic phosphate conc: 1.3 mM temperature: 313 K Ans. in 3 SFs.arrow_forward
- A mature glycogen particle typically has 12 tiers of branches with 2 branches per tier and 13 residues per branch. How many glucose residues are in such a particle?arrow_forwardWhy does the lack of glucose 6-phosphatase activity in the brain and muscle make good physiological sense? Glucose 6-phosphatase allows cells to trap glucose in the cell; however, these tissues primarily rely on noncarbohydrate energy sources. Glucose 6-phosphatase allows cells to generate glucose through gluconeogenesis; however, gluconeogenesis only takes place in the liver. Glucose 6-phosphatase allows cells to release glucose into the blood; however, these tissues should never release glucose. Glucose 6-phosphatase provides glucose 6-phosphate for glycogen synthesis; however, these tissues do not need glycogen.arrow_forwardWhich of the following statements about sugar polymers and glycosaminoglycans is/are true? Glucosamine, an amino sugar, would be positively charged physiologically unless it is part of an amide bond. Chitin is a homopolymer of GlcNac in beta 1--> 4 linkages. Amylose is a homopolymer of glucose containing alpha 1--> 6 linkages. Amylopectin in a non-reducing sugar polymer consisting solely of glucose monomers. Agarose is a highly charged sugar polymer used in electrophoresis. A core of hyaluronan protein is linked to an aggrecan polysaccharide in the extracellular matrix around joints and tendons. Mucins are secreted proteins that contain branched oligosaccharides linked to serine residues. None of the options shown is true. The glycosaminoglycan "hyaluronic acid" would carry more negative charge overall when compared to a polymer of "chondroitin" of the same length.

- The energy for the production of ATP comes from the breakdown of a glucose molecule via many enzyme-mediated chemical reactions occurring at several distinct stages of cellular respiration. During this time, the chemical energy stored in glucose is continually trans- ferred across these reactions.

- Carbon dioxide is considered to be a "waste" product of cellular respiration. Yet, there are still electrons, in the bonds between the C and O atoms.
