Quoted: PhysOrg news: A midsection between the head and the long tail of sperm contains mitochondria, organelles that generate a cell's power. But sperm have also developed a second energy source to power their long tail. They employ a process known as glycolysis, which breaks down glucose to derive ATP, which cells use for energy.
The pathway for glycolysis requires 10 enzymes. Using special "targeting domains," sperm tether these to a fibrous sheath that runs the length of the tail. In this study, the researchers are trying to re-create this glycolytic pathway by modifying each protein's targeting domain so that they can instead bind to nickel ions on a manufactured chip.
