Chapter 4 Part 5 Flashcards
(18 cards)
What is the significance of Snow’s work in supporting the germ theory?
It provided crucial evidence for the connection between germs and disease transmission.
Snow’s work involved studying cholera outbreaks and tracing the source to contaminated water.
What type of bacteria is Clostridium botulinum?
It is an endospore-forming bacterium that causes botulism.
Botulism is a serious form of food poisoning that can be fatal.
Why is it difficult to kill Clostridium botulinum in contaminated food?
Because it forms endospores that are resistant to heat and other methods of destruction.
Endospores can survive extreme conditions, making them challenging to eliminate.
What are some examples of bacterial structures that might be used as antibiotic targets?
- Cell wall components
- Ribosomes
- DNA replication machinery
Targeting these structures can disrupt bacterial growth and survival.
How are peroxisomes similar to mitochondria?
Both are involved in metabolic processes and energy production.
However, they differ in their specific functions and the types of reactions they catalyze.
How do peroxisomes differ from mitochondria?
Peroxisomes primarily break down fatty acids and detoxify harmful substances, while mitochondria are responsible for ATP production.
Mitochondria have their own DNA and are involved in cellular respiration.
Why must the functions of lysosomes and peroxisomes be compartmentalized?
To prevent harmful reactions from affecting other cellular components.
Compartmentalization ensures that enzymes and byproducts are contained within specific organelles.
What is a good example of staphylococci?
Staphylococcus aureus
This bacterium is commonly associated with skin infections and food poisoning.
Fill in the blank: The causative agent of botulism is _______.
