Explanation:

The cell wall of bacteria is made of peptidoglycan, which consists of alternating N - acetylglucosamine (NAG) and N - acetylmuramic acid (NAM) sugar units. So the first blank (after NAG and) should be filled with NAM. For the part about the structure connecting through the membrane in Gram - negative bacteria, porins are proteins that form channels in the outer membrane of Gram - negative bacteria, allowing molecules to pass through.

Answer:

1. The first blank (after NAG and) answer: NAM
2. The structure in Gram - negative bacteria membrane: porin
