Question

Which of the following processes occurs in the mitochondria?
cellular mutations
cellular respiration
transcription
translation

Answer 1

Answer:

Process that occurs in the mitochondria is cellular respiration (second option).

Explanation:

Cellular respiration consists of the process in which an energetic substrate, such as glucose, is oxidized for energy, in the presence of oxygen. This process occurs in a cellular organelle called the mitochondrion.

In the mitochondria, oxidative phosphorylation and the electron transport chain occur as part of energy production, processes that are linked to produce cellular respiration and obtain energy in the form of ATP.

The other options are not correct because:

• Cellular mutations occur at the molecular level, in the DNA.
• Transcription occurs in the cell nucleus.
• Translation occurs in the cytoplasm, with the participation of mRNA and ribosomes.
