No, I don't rememeber sitting for any exam in the last 6 or 7 years....
And For this I trust my less than perfect memory
No grades for me, I just need to convince people to publish my papers. And I am not sure it is easier.
For Gram - bacteria, the antibiotics work less efficiently due to the fact they have a lipopolysaccharide layer. The gram + bacteria lack this which allows more antibiotics to prove useful in treating these bacteria.

The main differenece between Gram= and Gram- is Gram+ have a thincker cellular wall and lack that lipoproteic membrane at the exterior that Gram- have. That membrane is similar in structure to the plasma membrane

So Gram - bacteria are more resistant to ALL antibiotics and not those that just target the cell wall (NAG and NAM)? Does the lipoproteic layer just protect it from the antibiotics?
