Which statement is true?
Cellular respiration takes place in the cytoplasm and the nucleus.
Cellular respiration takes place in the cytoplasm and the Golgi apparatus.
Cellular respiration takes place in the cytoplasm and mitochondria.
Cellular respiration takes place in mitochondria and chloroplasts.
Cellular respiration takes place in the cytoplasm and mitochondria.
The statement that is true is: Cellular respiration takes place in the cytoplasm and mitochondria.
To determine which statement is true, we need to understand where cellular respiration takes place within a cell.
Cellular respiration is the process by which cells convert nutrients into energy in the form of ATP (adenosine triphosphate). It occurs in the presence of oxygen and takes place in specialized structures within a cell called mitochondria.
Looking at the statements:
1. Cellular respiration takes place in the cytoplasm and the nucleus. - This statement is incorrect because the nucleus is not involved in cellular respiration. The nucleus is responsible for controlling the cell's activities and contains DNA.
2. Cellular respiration takes place in the cytoplasm and the Golgi apparatus. - This statement is also incorrect as the Golgi apparatus is involved in packaging and modifying proteins, but not in cellular respiration.
3. Cellular respiration takes place in the cytoplasm and mitochondria. - This statement is correct. Cellular respiration does occur in the cytoplasm but mainly takes place within the mitochondria, which are membrane-bound organelles found in most eukaryotic cells.
4. Cellular respiration takes place in mitochondria and chloroplasts. - This statement is incorrect. Chloroplasts are only found in plant cells and are responsible for photosynthesis, but they are not involved in cellular respiration.
Therefore, the statement "Cellular respiration takes place in the cytoplasm and mitochondria" is true.
