Measuring mitochondrial respiration in frozen tissue samples provides the first comprehensive atlas of how aging affects mitochondrial function in mice.

One of the most momentous events in the history of life involved endosymbiosis—a process by which one organism engulfed ...

Endosymbiosis, the process by which one organism engulfed another and integrated its DNA and functions into itself rather ...

Scientists found molecular evidence supporting the idea that chloroplasts originated as energy-generating organelles and only later evolved to support carbon assimilation in plant cells.

Photosynthesis occurs in chloroplasts ... as cellulose found in the cell walls and starch used as energy storage. The glucose can also be broken down in the plant by respiration.

These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose. Then, via respiration processes, cells use oxygen and glucose to synthesize energy ...
