1- In peptidoglycan, the adjacent rows linked by Tetrapeptide side chains, which
consist of five amino acids attached to NAMs in the backbone (
).
----------------------------------------------------------------------------------------------------2- Lysozyme is digestive enzyme that occurs naturally in tears and saliva (
).
--------------------------------------------------------------------------------------------------3- Lipid A is the lipid portion of the LPS which functions as an antigen (
).
----------------------------------------------------------------------------------------------------4- The return of an endospore to its vegetative state is called germination (
).
----------------------------------------------------------------------------------------------------5- L cells form can live and divide or return to the walled state (
).
----------------------------------------------------------------------------------------------------6- Prokaryotic plasma membranes are rigid because they have sterols (
