Study Notes

Role of Coenzymes The functional role of coenzymes is to act as transporters of chemical groups from one reactant to another. Ex. The hydride ion (H+ + 2e-) carried by NAD or the mole of hydrogen carried by FAD; The amine (-NH2) carried by pyridoxal phosphate…

 Beta - Adrenergic Blocking Agents     Mechanisms of Action     - Initial decrease in cardiac output, followed by reduction in peripheral vascular resistance.  - Other actions include decrease plasma renin activity, resetting of baroreceptors,  release of vasodilator prostaglandins, and blockade of prejunctional beta-receptors.   Advantages  - Documented reduction in cardiovascular morbidity and mortality.…

it's the individual pressure exerted independently by a particular gas within a mixture of gasses. The air we breath is a mixture of gasses: primarily nitrogen, oxygen, & carbon dioxide. So, the air you blow into a balloon creates pressure that causes the balloon to expand (& this pressure is generated as all the molecules of nitrogen, oxygen, & carbon dioxide move about & collide with the walls of the balloon). However, the total pressure genera…

Theories of Tooth Movement Pressure-Tension Theory: Concept: This theory posits that tooth movement occurs in response to the application of forces that create areas of pressure and tension in the periodontal ligament (PDL). Mechanism: When a force is applied to a tooth, the side of the tooth experiencing pressure (compression) leads to bone resorption, while the opposite side experiences tension, promoting bone deposition. This d…
