Cell Biology
What does Cell Biology study?
The cell structure and function
Its function is to keep the cell healthy and be a gate so substances and nutrients can go in and out.
Cell membrane
Name of the extraloop of genes. Resposible for antibiotic resistance.
Plasmid
What's a virus?
Microscopic parasite that can have DNA or RNA.
Toy Story
How do cells reproduce?
Name the three most important parts of the Mitochondria in order to create ATP.
Outer membrane, matrix and intermembrane space.
We can classify bacteria depending on:
Shape (spherical, comma, rod, corkscrew, spiral) and cell walls (gram positive and negative)
How can we classify them?
Depending on their morphology (helical, polyhedral, spherical and complex) and chemical composition (RNA or DNA).
Name of the possessed hotel in The Shining?
The Overlook Hotel
How does mitosis happens?
The cell creates two identical nucleus and then, it divides.
What happens in the RER and SER?
RER - folding of proteins
SER - creation of lipids (vesicles)
How do bacteria communicate and how can they survive?
They communicate thanks to quorum sensing and they survive thanks to endospores.
What's a virion? What's its function?
A virion is a fully assembled infectious virus and its function is to deliver DNA or RNA to the host.

Difference between sterilization and disinfection?

How do they survive? How can we kill them?
They survive thanks to their capsid and we can't kill them but inactivate them yes.
Which country was the first to give women the right to vote?
New Zealand (in 1893)
What are the subfields of cell biology?
Cell metabolism, genetic of cells, components structure, cell communication and cell cycle.
Cellular respiration, cell cycle, cell metabolism and cell transport.
How does antibiotic resistance happens?
The bacteria gets used to the antibiotic thanks to the misuse of them. They mutate (plasmids) and pass the info to other bacteria.
1. Access the host body
2. Attach to the host cell surface
3. Move across the outer cover of the cell
4. Hijack cellular machinery
5. Spread
