Photosynthesis: Crash Course Biology #108. Hank explains the extremely complex series of reactions whereby plants feed themselves on sunlight, carbon dioxide, and water, and also create some byproducts we’re pretty fond of as well.
You would be dead without plants and their magical, nay SCIENTIFIC, ability to convert sunlight, carbon dioxide, and water into glucose and pure, delicious oxygen. This happens exclusively through photosynthesis, a process that was developed 450 million years ago and actually, rather, sucks.
Photosynthesis is a powerful process that is responsible for some of life’s most vital functions. In fact, consumers like us rely on photosynthetic producers...

How do you turn light energy into chemical energy? Find out how plants perform this amazing energy transformation. We'll dive into the properties of light, how chlorophylls and other pigments absorb light, and how the absorbed energy is stored in chemical bonds.
In the Calvin cycle, energy storage molecules from the light-dependent reactions are used to capture (fix) carbon dioxide molecules and build sugars. Learn more about how this important cycle works.
The Calvin cycle enzyme rubisco is essential...but it also has a bad habit. Rubisco sometimes acts on oxygen rather than carbon dioxide, leading to a carbon-wasting side process called photorespiration. Learn about the strategies C4 and CAM plants use to minimize photorespiration.

In fact, consumers like us rely on photosynthetic producers to harness energy from the sun so that we can survive and thrive. In this episode of Crash Course Biology, we’ll explore photosynthesis in two acts, and learn how the process works inside and out.
