In sprouting seeds, fatty acids are broken down specifically within glyoxysomes. The glyoxylate cycle, which occurs in fat-rich tissues like germinating seeds, involves enzymes that are absent in mammals and are located in specialized organelles called glyoxysomes. Where can glyoxysomes be found?

1. Glyoxysomes are present in all types of eukaryotic cells.
2. Glyoxysomes are present in sprouting seeds.
3. Glyoxysomes are located within mitochondria.
4. Glyoxysomes are located within chloroplasts.

Correct answer: Glyoxysomes are present in sprouting seeds.

Solution

Glyoxysomes are specialized peroxisomes found in germinating seeds where they play a role in the glyoxylate cycle, converting stored fats into carbohydrates. They are not present in all eukaryotic cells or organelles like mitochondria or chloroplasts.
