53. Combustion of carbohydrates, like in a fireplace, is a reduction-oxidation reaction in which the carbon atom is oxidized and the oxygen atom is reduced, producing water and carbon dioxide. Oxidative phosphorylation and glycolysis are also reduction-oxidation reactions that produce…
Examine the data pictured. The table shows the amount of oxygen consumed (third column) by different animals (first column) at different temperatures. The type of apparatus employed in this investigation measures the changes in volume of air to detect the…
25. Apply your understanding of how living organisms use energy to argue in favor of why it is either beneficial or detrimental for cells to use ATP rather than directly using the energy stored in the bonds of carbohydrates to…
1. What is the most important energy currency used by cells? 2. What happens when a chemical is reduced during a reaction? 3. Which pair of molecules are both oxidizing agents? 4. Which of the following reactions releases energy? 5.…

57. Activation energy is required for a reaction to proceed, and it is lower if the reaction is catalyzed. Sucrose (table sugar) is a disaccharide. When we eat sucrose it is converted to carbon dioxide and water, as with other…
46. Cell metabolism is a complex process that uses many types of chemicals in a variety of processes. Which of the following statements provides the best and most accurate evidence of this concept? 47. Which pair of descriptors of chemical…
29. Describe the connection between anabolic and catabolic chemical reactions in a metabolic pathway. 30. Does physical exercise involve anabolic processes, catabolic processes, or both? Give evidence for your answer. 31. Which statement provides the most accurate evidence to support…
1. Energy can be taken in as glucose, then has to be converted to a form that can be easily used to perform work in cells. What is the name of the latter molecule? 2. When cellular respiration occurs, what…
