Does Nature Have Rights?

Release Date
Duration 00:27:51

Ecuador became the first country to enshrine the “rights of nature” in its constitution—granting wild species legal rights to exist. Today, conservationists are using it to save biodiversity hotspots.

Electron Transport Chain

This animation shows how the enzyme complexes of the electron transport chain harvest energy from cofactor molecules to pump protons across the mitochondrial membrane and establish a chemical gradient. It is the fourth of six animations about cellular respiration. These animations bring to life the molecular engines inside mitochondria that generate ATP, the main source of chemically stored energy used throughout the body.
