Are glycolipids and glycoprotein intrinsic or extrinsic? My book tells me intrinsic but my teacher told me extrinsic and the internet is confusing me more.

They are extrinsic because they don’t go through the whole phospholipid bilayer, only through the first phospholipids.

are you using the OCR A Level textbook as it says 'glycoproteins are intrinsic' however in the back of the book questions, it says an example of an extrinsic protein is a glycoprotein.'

I am using the OCR A level textbook.
Glycoproteins are intrinsic - 5th paragraph on page 104 "Glycoproteins are intrinsic proteins"
Glycolipids are extrinsic - 10th paragraph on page 204 "they [glycolipids] are lipids with attached carbohydrate (sugar) chains". Therefore, as lipids are extrinsic by nature, hence a phospholipid bilayer (2 layers of extrinsic lipids), a lipid with a carbohydrate chain attached remains extrinsic.

Hope this clears this up!
