Which protist group exhibits mitochondrial remnants with reduced functionality?

slime molds

diatoms

parabasalids

dinoflagellates

parabasalids

Explanation:

Parabasalides have modified mitochondria to promote reduced functionality that favors your body as they are anaerobic organisms. Parabasalids have unique mitochondria. Parabasalide mitochondria are called hydrogenomasomes. Hydrogenosomes breathe anaerobically and release hydrogen as a byproduct. For this reason, we can say that these organisms exhibit mitochondrial remnants with reduced functionality.
