3. You are investigating an enzymatic reaction involved in the biosynthesis of an amino acid. Based on your knowledge of biosynthetic pathways, which of the following properties would you NOT expect to apply to the reaction? a. The reaction by itself will likely have positive deltaG. b. The reaction will be classified as spontaneous. c. This reaction may require coupling to ATP hydrolysis to proceed. d. The reaction is part of anabolism. e. In an energy diagram, the products of this reaction will be at a higher energetic level than the substrates.
4. Which of the following statements about reactions classified as spontaneous is NOT true? a. In a thermodynamic sense, the reaction has the capacity to proceed. b. This reaction will release energy. c. The activation energy barrier in this reaction is required to keep the reaction products stable. d. Energy needs to be added to this reaction to overcome the activation energy barrier. e. The reaction will have an overall negative change of Gibbs free energy.
5. Which of the following statements about photosynthesis is NOT true? a. Without the input of light energy, photosynthesis is an endergonic process. b. The final step of the photosynthetic electron transport chain leads to the production of oxygen from water. c. During photosynthesis, ATP is produced using ATP synthase. d. Photosynthesis creates a proton gradient. e. During photosynthesis, the dark reactions lead to the production of glucose.
