Eukaryotic Structures
Do eukaryotes have peptidoglycan?
No! That is unique to bacteria!
Instead, they have chitin found in fungi.
Smooth ER's job?
Produce lipids and other molecules needed to later modify proteins.
Viruses are living cells. True or False?
False: they are best described as active or inactive organism that need hosts for metabolism and replication
Viruses have DNA and RNA. True or False?
False: they can have DNA OR RNA, never both (the "or" is key)
Aerobic bacteria need large amounts of oxygen, making oxygen what vocab term?
Macronutrient
Is E. coli a protozoan.
NO. No no no.
Protozoans are large single celled eukaryotes like amoebas and E. coli is bacteria.
Where are digestive enzymes?
Lysosomes
Which viral component surrounds DNA or RNA to keep it safe?
Capsid: made of capsomere proteins
Which viral component is made of stolen host parts?
Envelope (which is optional btw)
Isotonic Solution
Water/Salt is the same inside and outside the cell.
Wild card, how much will you bet (based on eukaryotic lecture)
Are frogs eukaryotes?
What is the order of nature's assembly line?
Nucleus > ER > Golgi
Bacteriophages attack?
Bacteria
Do bacteriophages need to "uncoat" to enter a host?
No, their DNA or RNA is directly injected into the host.
Acidophiles
Like acidic environments
You breath in fungal spores while gardening and develop a respiratory infection. What mycoses is this?
Systemic: contracted through lungs and sinuses
A mushroom needs carbon from decomposing trees to survive. This makes the mushroom what vocab term?
Chemoheterotrophic
Glycoprotein spikes help with what stage of the animal replication cycle?
Adsorption: they act as "keys" to "lock" into place on host cells
Define Lysogenic Converion
A stable long-term relationship between the phage and its host in which the phage DNA becomes incorporated into the host genome
4 Stages of Growth Curve: can you give me 1?
Lag: adjustment
Log: rapid growth
Stationary: death and growth "pause"
Death: rapid death
Compare and contrast flagella in eukaryotes and prokaryotes
Euk: large, few, whip-like motion
Prok: small, numerous, circular motion
This molecule in eukaryotic cell membranes provides the cell with structural support.
Cholesterol
Ways a virus can be released?
Lysis, Budding
Oncoviruses cause?
Cancer
How are Osmosis and Phagocytosis different?
Osmosis: natural movement of water from high to low, no energy needed
Phagocytosis: active transport where things move low to high and need energy and protein carriers
