Which is FALSE?

• simple sugars are monosaccharides.

• DNA is made up of nucleotides.

• Proteins are made of amino acids.

• Monomers are made of polymers.

Some proteins are catalysts in chemical reactions, meaning they speed them up. What are these proteins called?

• monomers

• enzymes

• quickens

• neutrons

Which is NOT a function of proteins?

• They provide a hydrophobic membrane

• They act as antibodies in the immune system

• They make-up structures such as muscles

• They regulate cell processes by helping to speed up chemical reactions (enzymes)

A protein denatures when

• temperature rises above functional level

• its 3D structure is compromised, but its primary structure remains

• it increases in function

• A and B

The quaternary structure of a protein is

• the simplest structure

• the most complex level

• is less complex than tertiary structure

• is less complex than primary structure

Which of the following macromolecules is hydrophobic (repels water), and so makes them perfect for forming membranes.

• lipids

• carbs

• proteins

• nucleic acids

Carbon is perfect for forming large macromolecules because

• Carbon can bond with up to 4 other atoms.

• Carbon can bond with other carbon atoms, forming rings and branched chains.

• Carbon cannot form covalent bonds.

• A and B
