Document Summary

Metabolism- sum of all chemical reactions and e transformation in an organism. Metabolic pathway- begins with specific molecule, ends with product. Energy (e): the capacity to do work (or supply heat) Potential energy- stored e, the capacity to do work. 1st law of thermodynamics- e cannot be created or destroyed, only converted from one form to another conservation of e. 2nd law of thermodynamics- every e transfer or transformation increase entropy in the universe. Entropy (s)- measure of disorder randomness. (usually heat) (1) (2) Free energy (g)- e available to do work. The stud that we can keep and sue in. biological systems.

Kinetic energy release when bonds are broken, have a negative free energy (less energy stored in products). Summary: sunlight- source of e for biological systems. Has 3 phosphate groups and this is where most energy is stored.

Please think about an enzyme's role in metabolism and the processes of Anabolism and Catabolism. Comment toward's how enzymes work and tie it to a Macro (or large scale) example -OR- comment on catabolism/anabolism and tie either to a Macro (large scale) example.

Through the course, youâve learned about many different catabolic and anabolic processes. Choose any one catabolic pathway AND any one anabolic pathway that we learned about in this course. Use these two pathways as examples of the general metabolic principles of catabolism and anabolism youâve learned about in this course. Make sure to describe the general purpose and major reactants and products of each of the pathways and how each pathway exemplifies principles of metabolism. (8 sentence maximum)
