1) Nucleus
2) Mitochondria
3) Endoplasmic reticulum
4) Golgi apparatus

Answer 1

Cellular respiration takes place in the mitochondria of the cells.

Step-by-step explanation:

The process of cellular respiration takes place in the mitochondria of the cells.

In the first stage, called glycolysis, glucose is broken down in the cytoplasm of the cell. Then, the pyruvate molecules produced in glycolysis are transported into the mitochondria for the next stages.

During the second stage, the pyruvate enters the Krebs cycle in the matrix of the mitochondria. Finally, in the third stage, called oxidative phosphorylation, the energy carriers enter the electron transport chain on the inner membrane of the mitochondria.
