Pharmacology
This course by Academy Europe presents condensed and succinct descriptions of relevant and current Board-driven information pertaining to pharmacology without the usual associated details. It is not meant to be a substitute for the comprehensive presentation of information and difficult concepts found in standard pharmacology texts. https://youtu.be/B48jrtNBAPY Each chapter includes…
Regulation, Apoptosis, Mitosis and Replication of DNA
This course explains the semiconservative replication of DNA and the role it plays in the cell cycle. The phases of the cell cycle and mitosis (prophase, metaphase, anaphase, and telophase), as well as the regulatory mechanisms associated with cyclins and their antagonists, are all relevant topics in medical exams. Table…
Energy, Enzymes and Metabolism
Metabolism is the sum of both catabolism (pathways that break down molecules for generation of cellular energy) and anabolism (pathways that build macromolecules using cellular energy). Here, we will discuss metabolism with regards to the Laws of Thermodynamics, Enzymology, and go over some of the major metabolic pathways utilized by…
Biological Membranes
Biological Membranes are comprised of phospholipid bilayers that are formed when the nonpolar tails of glycerophospholipids and sphingolipids interact with each other in a way that exposes their polar head groups to the aqueous extracellular environment. We will discuss how this thermodynamically driven formation is dictated by the hydrophobic effect…
Biochemistry
Biochemistry is the study of life from a chemical perspective and asks how living organisms arose from biomolecules that are lifeless. These biomolecules can be isolated from organisms and examined individually, and they conform to both the chemical and physical laws that govern inanimate matter. A biochemist studies the properties…
Metabolic Regulation
Integration of cellular metabolism is controlled by insulin and the opposing actions of glucagon and epinephrine. When food is available in abundance, or when the body needs to make stored energy available, changes in the circulating levels of these hormones allow the body to respond accordingly. This discussion of metabolic…
RNA Basic Knowledge
Ribonucleic acid (RNA) is a polymeric molecule, which is implicated in different biological roles such as coding, decoding, expression of genes and regulation. Biological reactions within cells are catalyzed by some RNA molecules, which control gene expression and communicate responses to cellular signals. The structure of RNA is similar to…
Analytical Techniques in Biotechnology
Biotechnology is an emerging field that allows scientists to use analytical techniques to study the structure and function of biomolecules. Protein purification is an all but mandatory step for studying macromolecules, but this task is not necessarily easy. Several experimental methods, deductive logic, and even a little bit of luck…
Lipid Metabolism
Lipid metabolism is the process by which lipids are synthesized and degraded in cells. In this course, important lipids discussed are bile salts, cholesterols, steroids, and ketone bodies. Also covered in this course are the structures and functions of these types of lipids. The biosynthesis and metabolism of these lipid…
