In this episode of Crash Course Botany, we’ll explore how the processes of photosynthesis and cellular respiration work, why they’re so critical for all life on Earth, and how they’re ...

Cellular respiration occurs in multiple stages: glycolysis, the citric acid cycle, and oxidative phosphorylation. Imagine a bustling city, full of people going about their daily activities.

Many diseases derive from problems with cellular respiration, the process through which cells extract energy from nutrients. Researchers have now discovered a new function for a protein in the ...

We assessed variability in the temperature dependence of ecosystem respiration within and among a range of aquatic and terrestrial environments using a global compilation of measurements of ...

It delivers oxygen and glucose to the tissues for respiration, which is the release of energy to cells. This video is about how arteries carry blood away from the heart. Find out more about GCSE ...

Animals, plants and many other living organisms inhale oxygen to "burn" (oxidize) compounds like sugar into CO 2 and water—a process during which the energy-rich molecule ATP is produced.
