Question

Which of the following statements about peroxisomes is FALSE?

a. Beta-oxidation in peroxisomes can shorten very long fatty acids.

b.Mammalian peroxisomes can synthesize some lipids, including bile salts.

c.In plants, peroxisomes and glyoxysomes serve as the site of βετα− oxidation.

d.Long chain fatty acids are transported into the peroxisome via a carnitine carrier protein where they are activated for oxidation.

Answer 1

FALSE statement among the followinig is

Option d: Long chain fatty acids are transported into the peroxisome via a carnitine carrier protein where they are activated for oxidation.

This statement is false because the long chain fatty acids enter the peroxisomes in a way that includes activation in the extraperoxisomal space which is followed by transport across the peroxisomal membrane and this transport is dependent on peroxisomal ATP binding cassette proteins.
