Where is catalase likely to be located in cells without peroxisomes?
Understand the Problem
The question is asking about the likely location of the enzyme catalase in cells that do not have peroxisomes. It is important to identify where this enzyme is found in such cells, as peroxisomes are known to contain catalase that breaks down hydrogen peroxide.
Answer
Catalase is found in the cytosol of cells without peroxisomes.
Catalase is located in the cytosol of cells that are deficient in peroxisomes.
Answer for screen readers
Catalase is located in the cytosol of cells that are deficient in peroxisomes.
More Information
In cells with peroxisomes, catalase is typically localized within these organelles due to their role in decomposing hydrogen peroxide. However, in the absence of peroxisomes, catalase is distributed in the cytosol where it still functions to protect the cell from oxidative damage.
Tips
A common mistake may be assuming that if peroxisomes are absent, catalase is not present at all. Instead, it relocates to the cytosol.
