Rough endoplasmic reticulum
D
Mitochondrion
Verified step by step guidance1
Identify the process described: aerobic respiration is the metabolic pathway where cells extract energy from nutrients in the presence of oxygen to produce ATP, the energy currency of the cell.
Recall the main cellular organelles involved in energy metabolism: the Golgi apparatus is involved in protein modification and sorting, lysosomes are responsible for degradation of waste materials, and the rough endoplasmic reticulum is involved in protein synthesis.
Understand that the mitochondrion is known as the 'powerhouse of the cell' because it is the site where aerobic respiration occurs, specifically in the mitochondrial matrix and inner membrane.
Recognize that during aerobic respiration, nutrients like glucose are broken down through glycolysis (in the cytoplasm) and then further processed in the mitochondrion through the Krebs cycle and oxidative phosphorylation to generate ATP.
Conclude that the mitochondrion is the cellular structure where energy is extracted from nutrients to produce ATP during aerobic respiration.
