The statements below about Anabolic Pathways are false. Rewrite each to make it true. 1. They depend on enzymes. 2. They are usually highly spontaneous. 3. They consume energy to build polymers from monomers. 4. They release energy as monomers to polymers. Choose the correct answer choice below and use it to explain how the second law of thermodynamics applies to metabolic reactions. Explain why the answers you did not choose are inaccurate. 1. Metabolic reactions release energy. 2. Non-spontaneous metabolic reactions require an input of energy. 3. Spontaneous metabolic reactions increase the entropy of the universe.

Which is true regarding catabolic processes? Overall, such processes require net energy input. They generally lead to the formation of smaller, simpler molecules. Such processes are typically coupled, or linked, to ATP hydrolysis reactions (i.e. ATP to ADP). None are true; A-C are all false statements.

Which of the following is TRUE for exergonic reactions? The products have more free energy than the reactants. The products have less free energy than the reactants. Exergonic reactions can always be completed spontaneously. An input of energy from the surroundings is required for the reactants to proceed. The reactions upgrade the free energy of the products at the expense of energy from the surroundings. ATP generally energizes cellular processes by releasing heat upon hydrolysis, acting as a catalyst for the direct chemical transfer of a phosphate group. By releasing an inorganic phosphate, it drives reactions by coupling with them. Light flashes can also energize chemical reactions. Which of the following statements is TRUE concerning catabolic pathways? They combine molecules into more complex and energy-rich molecules. They are usually coupled with anabolic pathways, which supply energy in the form of ATP. They involve endergonic reactions that break down complex molecules into simpler ones. They are spontaneous and do not need enzyme catalysis. They build up complex molecules such as proteins from simpler compounds. In an organism, the energy available for work is called free energy because it can be obtained without any cost. It can be spent with no cost to the universe. An organism can live off of it if necessary, and it is available for work. It is equivalent to the system's total energy.
