December 8‚ 2013 PSY 200 Reflection Prelude- When signing up for psychology 200‚ I expected it to be a very interesting course much like my class from high school. With such an interest in psychology‚ I hoped that this course would help determine if this was a potential major/minor to pursue. Aside from its academic aspect‚ I took psychology to gain some personal insight. With a mother diagnosed with bipolar disorder‚ along with other family members as well as myself suffering from depression

Able‚ Not Adulterous In the timeless novel The Scarlet Letter by Nathaniel Hawthorne‚ the scarlet letter “A” is meant to be a symbol of shame and punishment given by the Puritan elders of Boston to Hester Prynne for the crime of adultery; when the story opens‚ the identity of her lover is unknown‚ but it is revealed later to be the Reverend Dimmesdale. In the Puritan society‚ the townspeople shun Hester for her sinfulness. The letter on Hester’s clothing intended to publicly humiliate and shame

Bacterial Energetics and Membranes Abstract The Mg2+/Ca2+ ATP synthase present in all bacterial membranes‚ particularly E. coli‚ couples ATP synthesis to the proton (H+) gradient produced by the ETC‚ a process known as oxidative phosphorylation. The gradient acts to power the ATPase‚ so that it may phosphorylate ADP to produce ATP. The reverse reaction of this process‚ or hydrolysis of ATP into ADP and Pi‚ may be used to observe ATPase activity when the resulting Pi is quantitatively measured

Membrane Behavior Lab Abstract: Introduction: The permeability of a cell to solutes in an aqueous medium depends upon the physical and chemical make–up of the membrane. The maintenance of the living cell depends upon the continued presence and functioning of a selectively permeable membrane. If the nature of the membrane is changed or altered in any way‚ this may well affect its permeability and thus the properties of the cell of which it is a part. Irreversible changes in the permeability

The plasma membrane is a fluid phospholipid bilayer. The outside of the bilayer is hydrophilic portions of porteins and phospholipids because they are exposed to water. This results in a stable membrane structure. Inside the bilayer hydrophobic portions of proteins and phospholipids because the inside of the bilayer is nonaqueous. the proteins bob in the fluid bilayer of phospholipids. The proteins also vary in structure and function. There are teh integral proteins; transmembrane
