which statement is true? ( 1 point )
A.) Cellular respiration takes place in the cytoplasm and the nucleus.
B.) Cellular respiration takes place in the cytoplasm and mitochondria
C.) Cellular respiration takes place in the mitochondria and chloroplasts
D.) Cellular respiration takes place in the cytoplasm and the Golgi apparatus
B.) Cellular respiration takes place in the cytoplasm and mitochondria
The true statement is B.) Cellular respiration takes place in the cytoplasm and mitochondria.
To determine which statement is true about the location of cellular respiration, let's break down each of the options:
A.) Cellular respiration takes place in the cytoplasm and the nucleus.
The cytoplasm is where various cellular processes occur, but cellular respiration does not primarily occur in the nucleus. The nucleus is responsible for housing genetic material (DNA), but it does not play a direct role in cellular respiration. Therefore, Statement A is incorrect.
B.) Cellular respiration takes place in the cytoplasm and mitochondria.
Cellular respiration is a metabolic process that generates energy in the form of ATP (adenosine triphosphate). It occurs in the cytoplasm (specifically in the cytosol) and mitochondria of the cell. The mitochondria, often referred to as the "powerhouse" of the cell, is responsible for the majority of ATP production through cellular respiration. Therefore, Statement B is the correct answer as it accurately identifies the locations where cellular respiration occurs.
C.) Cellular respiration takes place in the mitochondria and chloroplasts.
Chloroplasts are only found in plant cells and are responsible for photosynthesis, not cellular respiration. Therefore, Statement C is incorrect.
D.) Cellular respiration takes place in the cytoplasm and the Golgi apparatus.
The Golgi apparatus primarily functions in protein modification, processing, and packaging, and it does not directly participate in cellular respiration. Therefore, Statement D is incorrect.
In conclusion, the statement that is true is B.) Cellular respiration takes place in the cytoplasm and mitochondria.
