Question

Some anaerobic protists obtain energy using _________

1) mitochondria.
2) cytochromes.
3) hydrogenosomes.
4) All of the choices are correct.

Answer 1

Anaerobic protists obtain energy using hydrogenosomes, specialized organelles that enable energy production in the absence of oxygen.

Step-by-step explanation:

Some anaerobic protists obtain energy using hydrogenosomes. While mitochondria and cytochromes are associated with aerobic energy-producing pathways, hydrogenosomes are specialized organelles that help certain eukaryotic microorganisms, such as some protists, to produce energy anaerobically. In such organisms, hydrogenosomes have replaced mitochondria and are involved in metabolic processes that do not require oxygen.
