Respiration close respirationA chemical reaction that occurs in the mitochondria of cells in which glucose and oxygen react to produce carbon dioxide and water, releasing energy. is a chemical ...

A plant's success may depend on how well the three sets of genetic instructions it carries in its cells cooperate, according to a new study led by plant scientists at Penn State. In an analysis of the ...

First and foremost, we breathe in order to absorb oxygen—but this vital rhythm could also have other functions. Over the past few years, a range of studies have shown that respiration influences ...

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 ...

Cheyne-Stokes respiration, or periodic respiration, involves an atypical pattern of breathing. It consists of cycles of deep breathing followed by shallow breathing. Cheyne-Stokes breathing can be a ...

Here we describe the case of a patient (Patient 1) who was hospitalized for non–ST-segment elevation myocardial infarction. After the patient underwent complete revascularization for three-vessel ...

Painful respiration can involve lung pain that occurs when a person breathes in or out. Infections, musculoskeletal injuries, and heart problems can cause this pain. The lungs do not have pain ...
