which statement is true
cellular resperation takes place in the cytoplasm and mitochronda
cellular resperation takes place in mitochondria and chloroplast
cellular resperation takes place in cytoplasm and Golgi apparatus
cellular resperation takes place in cytoplasm and nucleus
The statement "cellular respiration takes place in the cytoplasm and mitochondria" is true.
The statement "cellular respiration takes place in the cytoplasm and mitochondria" is true.
The correct statement is: Cellular respiration takes place in the cytoplasm and mitochondria.
To determine the correct answer, we need to have a basic understanding of cellular respiration. Cellular respiration is the process by which cells break down glucose (sugar) and convert it into usable energy in the form of ATP (adenosine triphosphate). This energy is essential for various cellular processes.
Now, let's analyze each statement:
1. Cellular respiration takes place in the cytoplasm and mitochondria: This statement is correct. The initial step of cellular respiration, known as glycolysis, occurs in the cytoplasm. The subsequent steps, including the citric acid cycle (Krebs cycle) and electron transport chain, take place in the mitochondria.
2. Cellular respiration takes place in mitochondria and chloroplast: This statement is incorrect. While mitochondria are involved in cellular respiration, chloroplasts are responsible for photosynthesis, not respiration. Chloroplasts are found in plant cells and some algae, and they convert sunlight into energy-rich molecules like glucose.
3. Cellular respiration takes place in cytoplasm and Golgi apparatus: This statement is incorrect. The Golgi apparatus is responsible for packaging and modifying proteins and lipids, not for cellular respiration. It plays a role in protein transport within the cell, but it is not directly involved in energy production.
4. Cellular respiration takes place in cytoplasm and nucleus: This statement is incorrect. The nucleus is the control center of the cell, housing DNA, but it is not directly involved in cellular respiration. The energy-generating processes occur in the cytoplasm and mitochondria.
Therefore, the true statement is: Cellular respiration takes place in the cytoplasm and mitochondria.
