Archaea and Bacterial Motility

Flashcards covering the unique properties of Archaea cell walls and the structural components of bacterial flagella.

What are the characteristics of Archaea cell walls?

They may be wall-less or have walls of pseudomurein. Also atypical

What two components found in peptidoglycan are missing in pseudomurein?

NAM and D-amino acids.

What are the two main types of prokaryotic appendages in bacteria?

1. Flagella (for movement) and 2. Pili/Fimbrae (for attachment).

What are flagella?

Thread-like structures used for movement (motility) that act as bacterial "tails" for swimming.

How many flagella can be present on a single bacterial cell?

$1$ to hundreds per cell, depending on the bacterial species.

How many parts make up the structure of a flagellum?

Flagella have $3$ parts.

What is the filament of a flagellum?

The long outer part of the flagellum, which is $10-20$ times longer than the cell.

What protein is the filament of the flagellum made of?

Flagellin.
