You also learn why we need oxygen to stay alive and how poisons such as cyanide do their deadly work. Hemoglobin is the protein in red blood cells that carries oxygen from lungs to tissues and then takes away carbon dioxide for exhalation. Noting that biochemistry deals chiefly with just six bonding elements (out of the more than 100 in the periodic table of elements), Professor Ahern starts the course by stressing the subject’s underlying simplicity. As a novice, I wouldn't have noticed this except that Dr Ahern clearly states that the reaction from G6P to F6P doesn't change the number of atoms but only rearranges them. Biochemistry and Molecular Biology: How Life Works Reviews - page 2.

For this reason, telomerase might appear to be the secret to immortality except its unregulated presence in cells can lead to cancer. Starting with a review of previous material, Professor Nowicki sets the stage for the third major theme of the course, "Energy and Resources," which moves from the level of molecules to global ecosystems.... We look at the process by which cells obtain energy from a molecule called adenosine triphosphate (ATP).... Activation energy is the initial "push" required for a chemical reaction to proceed. Depending on your email provider, it may have mistakenly been flagged as spam. This professor is knowledgeable, organized, thorough, and concise. Similarly, proteins were once conventionally thought to have relatively fixed 3-D structures. His explanations are good enough, but rarely engaging. Then learn the deadly consequences of proteins that do not fold properly, leading to degenerative conditions such as Alzheimer's, Parkinson's, and prion diseases. This course is truly inspirational. I have to be honest and say this was the toughest course I have taken yet in the Great Courses I own. Thus far, your investigations have accounted for only part of the energy available from food.

However the course was very good and I would recommend it to a friend with a chemical background. This lecture outlines the challenges of evolution for living entities such as we recognize today, and reviews experimental data suggesting how these challenges might have been met. Zero in on DNA and how its double-helix structure relates to its function. If it is not found, please email customer service at ( or call 1-800-832-2412 for assistance. Producing the right proteins at the right time is only the first step. It's almost 75 years later, and we find ourselves in much the same position as Wells described in 1929. Caffeine fools the body—usually harmlessly—into increasing glucose in the blood, while too much fructose can lead to unhealthy accumulation of fat in the liver. Close by investigating techniques to create biological drugs on demand. Also look at strategies for reducing our reliance on environmentally unsound nitrogen fertilizers by exploiting the secret of 16-feet-tall corn plants found in Mexico.

It might be best appreciated in audio-only format. This course is a great reminder of why I enjoyed learning about this topic so much! Roughly 10,000 human diseases may be caused by mutations in single genes. A metabolic pathway is a series of biochemical reactions, where the product of one serves as the substrate for the next. Neurotransmitters, the Brain, and Addiction. For example, the relationship between an enzyme and its substrate (the substance on which it acts) was long portrayed as like a key fitting into a lock; the two had to match precisely, like puzzle pieces. Date published: 2020-08-24. Not only do these sciences tell us what’s happening at the most basic levels of living systems, but they also shed light on things such as: Drawing on years of classroom experience and his three popular textbooks, Professor Ahern conducts a graphics-intensive tour in which you always know where you are, even as you navigate the complex pathways of glycolysis and the Krebs citric acid cycle—two of the major stages leading from food to energy. He has been awarded fellowships from the Mary Flagler Cary Charitable Trust, the Alfred P. Sloan Foundation, and the John Simon Guggenheim Foundation. Investigate why water is so singularly suited to life. Enter the email address you used to create your account. Professor Nowicki describes the four earliest stages of animal development-fertilization, cleavage, gastrulation, and organogenesis-outlining the processes involved in each.... Developmental processes cause cells to differentiate into many different types of cells. Then trace the route for fatty acid oxidation. They have the ability to update the email address. Find that DNA repair can interfere with cancer treatment, when the malignant cells survive medical therapy by repairing their DNA faster than the treatment can halt the repair. Follow the metabolic pathway called glycolysis that breaks up glucose and other sugars. The increasing loss of biodiversity means that species diversity is decreasing at the very moment of our greatest strides in biological understanding. Also cover recent findings about gut bacteria that have changed our views about diet. Also see how variant forms of hemoglobin, such as fetal hemoglobin and the mutation behind sickle cell anemia, can have life-saving or fatal consequences—all depending on structure. We explore the nature of this mechanism and look at examples such as the regulation of body temperature.... Homeostasis requires the different parts of a complex organism to communicate with each other. Moved a tad quickly for my 70 year old mind so I had to pause a lot.

Examine the key steps in cholesterol synthesis, learn about its important role in membranes, and discover where LDLs (“bad” cholesterol) and HDLs (“good”) come from. It’s quite a trip! There is an abundance of detail, but it's not overwhelming because the lectures are organized and presented well, and the extensive graphics are of high quality and are very helpful. Great Course! If I were a bit younger in knowing what I know now, I am sure that Professor Ahern would have convinced me to pursue a career aimed at wrestling with the wonders of the life sciences. In the past century, progress in these complementary disciplines has been astonishing, and a week rarely passes without major advances in medicine, physiology, genetics, nutrition, agriculture, or other areas, where biochemistry and molecular biology are shedding new light on life. Consider the case of honeybees, where a special food affects which genes are expressed, turning an ordinary larva into a queen bee. Who is editing this stuff? Discover the handful of elements involved in biochemical reactions; the bonds they form; and the wide array of molecules that result, including amino acids, which are the building blocks of proteins.

These include flavors, dyes, caffeine, and even catnip. The answer is "yes and no." One reason biochemists care so much about enzymes is that many medical conditions result from enzyme activity that is excessive or insufficient. Apply new code? I found this course, Introduction to Biology, fascinating and a valuable update of my education of science. Talks include research and educational materials. Sorry, this feature is not available yet. Altruistic interactions are quite common, yet difficult to understand from an evolutionary perspective. The order of amino acids matters, but even more important are the shapes they form. Only with the accidental synthesis of urea (the principal component of urine) in 1828 did scientists begin to accept that ordinary chemistry might be behind living processes. Study how plants use sunlight and reduction reactions to build carbohydrates from carbon dioxide and water. Then follow the flow of nitrogen from bacteria to plants to us.
