Which statement is correct about organelles that provide energy?
1) They are responsible for cellular respiration.
2) Plasma Membrane
3) Golgi apparatus
4) Rough ER contains ribosomes, and smooth ER transports materials other than proteins
Recess is correct aug 2023!!!
I suppose it will be "none of these".
To determine which statement is correct about organelles that provide energy, we first need to understand which organelles are responsible for energy production within a cell. In eukaryotic cells, the two main organelles involved in energy production are mitochondria and chloroplasts.
1. Mitochondria: These organelles are often referred to as the "powerhouses" of the cell because they generate adenosine triphosphate (ATP), the molecule used by cells as a source of energy. Mitochondria are found in most eukaryotic cells and are involved in cellular respiration, a metabolic process that produces ATP through the breakdown of glucose and other organic molecules.
2. Chloroplasts: These organelles are specific to plant cells and some algae. They are responsible for photosynthesis, the process by which plants convert sunlight into chemical energy (specifically ATP) and synthesize organic compounds like glucose. Chloroplasts contain pigments called chlorophyll, which capture light energy for photosynthesis.
Now that we understand the organelles involved in energy production, we can evaluate the given statements:
a) "Mitochondria are responsible for photosynthesis." - This statement is incorrect. As mentioned earlier, mitochondria are involved in cellular respiration, not photosynthesis. Photosynthesis occurs in chloroplasts, not mitochondria.
b) "Chloroplasts produce ATP through the breakdown of glucose." - This statement is incorrect. Chloroplasts do not break down glucose to produce ATP. They generate ATP through the process of photosynthesis by capturing light energy and converting it into chemical energy.
c) "Mitochondria are commonly found in eukaryotic cells." - This statement is correct. Mitochondria are indeed present in most eukaryotic cells and serve as the primary site of ATP production.
Based on the explanations above, the correct statement is option c) "Mitochondria are commonly found in eukaryotic cells."
