Biological washing liquid contains lipase. A cook spills oil on a cotton shirt. Which statement describes how the lipase in the washing liquid helps remove the oil stain at 30 °C?
- Lipase breaks down the oil into smaller soluble molecules that can be washed away.
- Lipase converts the oil into starch which is easier to remove.
- Lipase coats the oil so that it sticks more strongly to the cotton fibres.
- Lipase changes the cotton so that it absorbs the oil completely.
