A) Which statement is true? (1 point)
Cellular respiration takes place in the cytoplasm and the nucleus.
Cellular respiration takes place in the cytoplasm and mitochondria.
Cellular respiration takes place in the cytoplasm and the Golgi apparatus.
Cellular respiration takes place in mitochondria and chloroplasts.
Cellular respiration takes place in the cytoplasm and mitochondria.
To determine which statement is true, we need to understand where cellular respiration takes place in a cell. Cellular respiration is a process that converts glucose (sugar) into energy, specifically in the form of ATP (adenosine triphosphate). This process occurs in the presence of oxygen and takes place in the mitochondria.
Now, let's analyze the given statements:
A) Cellular respiration takes place in the cytoplasm and the nucleus.
This statement is incorrect because cellular respiration primarily occurs in the mitochondria, not in the cytoplasm or the nucleus.
B) Cellular respiration takes place in the cytoplasm and mitochondria.
This statement is correct. Cellular respiration does occur in the cytoplasm and specifically in the mitochondria. The cytoplasm is the site where certain initial reactions of cellular respiration take place, and the mitochondria carry out most of the steps involved in the process.
C) Cellular respiration takes place in the cytoplasm and the Golgi apparatus.
This statement is incorrect. The Golgi apparatus is responsible for processing and packaging proteins and lipids, but it does not play a role in cellular respiration.
D) Cellular respiration takes place in mitochondria and chloroplasts.
This statement is partially incorrect. Mitochondria are indeed involved in cellular respiration, as explained earlier. However, chloroplasts are not involved in cellular respiration. Instead, chloroplasts are responsible for photosynthesis, a process in which plants convert light energy into glucose.
Therefore, the correct statement is B) Cellular respiration takes place in the cytoplasm and mitochondria.
