So yesterday we reviewed chapter 8, which was an introduction to metabolism. Here are some quick notes you should remember.
-Metabolism includes all of the chemical reactions in an organism.
-Catabolic pathways breaks down more complex molecules to simpler ones.
-Anabolic pathways makes complex molecules from simpler ones.
----To remember anabolic pathways, I thinking of anabolic steroids helps me. They are steroids that build up the body’s muscle mass. Don’t ask me why I know that.
-The first law of thermodynamics states that energy can be transferred and transformed but cant be created nor destroyed.
-The second law of thermodynamics explains that energy transfer or transformation increases the entropy, disorder, of the universe.
-Exergonic reactions proceeds with a net release of free energy
-Endergonic reactions absorbs free energy from its surroundings.
-Energy can be kenetic or potential.
-Kenetic: energy of motion. Ex: light and heat
-Potential: energy of position. Ex: arrangement or location.
-If it ends in –ase its an enzyme.
-Enzymes have three different inhibitors: competitive, noncompetitive and feedback.
These images may be helpful in better understanding the different inhibitors.
