CHEM 1240: Biochemistry

Discover the mechanics of voltage-gated Na+ channels and their role in neuron activity. This video breaks down key neuronal terms like resting potential and threshold to explain precisely when these channels open. You'll come away understanding that voltage-gated Na+ channels open at the threshold state initiating an action potential.

Learn about the path of blood flow in the mammalian heart and circulatory system. Discover how oxygen-rich blood from the lungs enters the left atrium and understand why other statements about blood flow are incorrect.

Learn about muscle fascicle patterns and their role in human anatomy. Our video zeroes in on the convergent pattern found in the pectoralis major. Compare this with other muscle types like the biceps brachii and gluteus maximus to deepen your anatomical knowledge.

Explore the distinct approaches of bioremediation and biological augmentation in managing environmental issues. Learn how organisms are utilized for pollutant degradation or enhancing ecological functions to mitigate environmental degradation.

Explore the secrets of fossilization in sedimentary rocks. Uncover how these rocks, like nature's archives, preserve the history of life on Earth over billions of years. Delve into the unique processes that create these historical records.

Explore the world of DNA replication by comparing it to climbing a staircase. Understand the roles of leading and lagging strands, and discover the importance of DNA Polymerase III in this intricate process.
