If a cell stains dark for the sdh test and light for the matpase test, how can we classify that cell?
BartSMP [9]

Cell stained light for the metaphase test and dark for the SDH, then we can classify the cell as an oxidative cell.

<h3>What is metaphase?</h3>

Metaphase, the second stage of mitosis, sees the chromosomes travel onto the spindle's equatorial plane.

<h3>What is the SDH test?</h3>
  • Oxidative cell stains are dark for the SDH test and light for the metaphase test.
  • SDH is an enzyme used in testing mainly to detect hepatocellular injury in cattle and horses.
  • SDH enzyme is also detected in human tissues. The major sites where the SDH enzymes are found in humans are kidneys, seminal vesicles and kidneys.
