Determine the correctness or otherwise of the following Assertion (a) ...
Plants produce glucose from fatty acids through a process called Kerbs cycle. Plants contain peroxisomes that function in the conversion of fatty acids to carbohydrates. The entire cycle is not due to peroxisomes. they are just a supporting element.
Determine the correctness or otherwise of the following Assertion (a) ...
Assertion: Plants convert fatty acids into glucose
- The assertion is **partially true**. Plants can convert fatty acids into glucose, but this process is not direct. Instead, fatty acids are first broken down into acetyl-CoA through beta-oxidation. Acetyl-CoA can then enter the gluconeogenesis pathway to ultimately form glucose. However, this conversion is not a primary pathway for glucose synthesis in plants, which primarily rely on photosynthesis for glucose production.
Reason: Plants have peroxisomes
- The reason is **true**. Peroxisomes are organelles found in plant cells that play a crucial role in the metabolism of fatty acids. They contain enzymes that facilitate the breakdown of fatty acids through beta-oxidation, which is essential for converting fatty acids into acetyl-CoA.
Relationship between Assertion and Reason
- Although both the assertion and the reason are true, the reason does not serve as a direct justification for the assertion. The presence of peroxisomes enables the breakdown of fatty acids, but they do not directly convert fatty acids into glucose. The conversion involves additional steps and metabolic pathways that extend beyond the role of peroxisomes.
Conclusion
- Therefore, the correct option is **(a)**: Both (a) and (r) are true but (r) is not the correct reason for (a). This means while the processes mentioned in both statements are valid, the relationship between them does not support the assertion directly.
