Animals, plants and many other living organisms inhale oxygen to "burn" (oxidize) compounds like sugar into CO2 and water—a process during which the energy-rich molecule ATP is produced. Cells require ...

A team of scientists have elucidated an ancient mechanism of cellular respiration. To that end, they studied bacteria that feed on the gases carbon dioxide and hydrogen, and turn them into acetic acid ...

All organisms need ATP to live. Respiration is only around 40 per cent efficient. As animals respire, heat is also released. In birds and mammals, this heat is distributed around the body by the ...

As animals respire, heat is also released. In birds and mammals, this heat is distributed around the body by the blood and helps to maintain a constant internal temperature.

Plants and animals have many similarities when it comes to what they need to survive. Both need water and air. We often think of animals using oxygen and glucose for cellular respiration and producing ...

1 The application of an electric current to the phrenic nerve was attempted as early as 1793 by Hufeland in Göttingen, Germany, two years after Galvani had recorded his observations on "animal ...
