Figure 1. Mitochondrial content and function in humans.

Figure 1

(A) Hundreds of mitochondria are present within various cells and organs across the body. (B) Mitochondrial content varies according to energy demand in different organs, where they perform multiple functions ranging from energy transformation, signaling, and hormone biosynthesis. (C) General schematic of a cell, its cytoplasm (green), nucleus (blue), and mitochondria (brown). Mitochondria are dynamic and undergo changes in shape through fusion and fission within minutes in response to external biochemical and energetic signals.
