Why Can't Cells Harness Heat for Work? Explained
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Discover why most cells are unable to utilize heat for work by exploring the principles of cellular thermodynamics. Learn how heat, as a form of kinetic energy, relates to cellular processes and why uniform temperature distribution within cells hinders their ability to harness heat effectively. Uncover the key factors that determine why cells can't perform work using heat.
Why Cancer Cells Remain Undifferentiated: Key Characteristics
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Explore the characteristics that distinguish normal cells from cancer cells in this informative video. Learn how normal cells perform specialized functions for overall health, while cancer cells grow uncontrollably. Discover why cancer cells lack differentiation, ignore reproduction control signals, and their connection to the absence of radical scavengers, all leading to their uncontrolled proliferation.
