- Describe whether each of the following substances serves primarily as an energy source, a form of stored energy, or a structural material some serve as more than one: a. cellulosec. glycogen b. sucrose, table sugard. starcharrow_forwardX Animals preserve as a form of energy in their bodies. Glucose Fat Starch Cellulosearrow_forwardFor a given acid HA, it was determined that at pH 6.0 the concentration of the conjugate base [A] was 0.075 M and the acid [HA] was 0.025 M. What percent of this acid is ionized at pH 6.0? What is the pKa of this acid? What pH would this acid be 50% lonized?arrow_forward
- The metabolism of glucose produces CO2 and H2O, how does the human body expect these reaction products?arrow_forwardThe number of ATP molecules consumed and produced during glycolysis under anaerobic conditions are summarized in the following diagram (the ATP hydrolysis and synthesis reactions are shown in green). Phosphate Carbon atom 2 ATP 2 ADP ●●●●●● Glucose I Energy-Investing Phase O 2 ATP O 6 ATP O 1 ATP 8 ATP NADH + NAD* +H* O 4 ATP ●●●● 2 ADP 2 ATP NADH + NAD +H Based on the diagram above, for each glucose molecule broken down, what is the net energy yield of glycolysis in terms of ATP under anaerobic conditions?

- Take a look at this organic reaction: iiii CH₂ CH₂ C с NAD NADH CH₂ CH₂ -C-C-CH₂-CH₂-C- __ + CO₂ The reactant molecule is re-drawn in the drawing area below. Highlight in red any groups in this molecule in which carbon atoms are oxidized by the reaction. Highlight in blue any groups in which carbon atoms are reduced. If no carbon atoms are oxidized or reduced, check the box under the drawing area. B Xarrow_forwardName the substances that are produced by the complete hydrolysis of this substancearrow_forward36. From the equation below, which statement is CORRECT?* CH,=CH2(g) + H,O(g) –H.SOL» CH;CH,OH(g) A. Ethanol can be prepared by oxidation reaction. B. Ethanol can be prepared by addition reaction. C. Water is combined with acetylene to produce ethanol. O D. Both B and Carrow_forward
