The correct Answer is:
To determine which points are not correct about red fibers, let's analyze each statement one by one. 1. **More myoglobin**: This statement is correct. Red fibers are rich in myoglobin, which is a protein that helps in oxygen storage and transport in muscle cells. 2. **More mitochondria**: This statement is also correct. Red fibers contain a higher number of mitochondria, which are essential for aerobic respiration, allowing these fibers to produce energy efficiently. 3. **More sarcoplasmic reticulum**: This statement is incorrect. Red fibers have less sarcoplasmic reticulum compared to white fibers. White fibers are more associated with anaerobic processes and have more sarcoplasmic reticulum to facilitate quick energy release. 4. **Depend on anaerobic process for energy**: This statement is incorrect. Red fibers primarily rely on aerobic respiration for energy production due to their high mitochondrial content. They do not depend on anaerobic processes. 5. **Gives a reddish appearance**: This statement is correct. The presence of myoglobin gives red fibers their characteristic reddish color. Now, summarizing the analysis: - Correct statements about red fibers: (i) More myoglobin, (ii) More mitochondria, (v) Gives a reddish appearance. - Incorrect statements about red fibers: (iii) More sarcoplasmic reticulum, (iv) Depend on anaerobic process for energy. ### Conclusion: The points that are not correct about red fibers are: - (iii) More sarcoplasmic reticulum - (iv) Depend on anaerobic process for energy ---
