Endospores Represent a Challenge to the Fields of Industrial and Medical

question 6

Multiple Choice

Endospores represent a challenge to the fields of industrial and medical microbiology because

• A)they are resistant to harsh environments,thus allowing survival of endospore-forming organisms under conditions in which non-endospore-forming cells would not survive.
• B)endospore-forming organisms are often dangerous pathogens.
• C)endospores are significantly smaller than vegetative cells.
• D) endospores are resistant to harsh environments,thus allowing survival of endospore-forming organisms under conditions in which non-endospore-forming cells would not survive,and endospore-forming organisms are often dangerous pathogens.

Definitions:

Postsynaptic Membrane

A specialized area of a cell membrane in a neuron, positioned after the synaptic gap, that receives signals from another neuron.

Acetylcholinesterase

An enzyme that breaks down acetylcholine, a neurotransmitter, in the synaptic cleft, effectively terminating the signal between nerve cells.

Synaptic Vesicles

Membrane-bound sacs in the presynaptic terminal of a neuron that store neurotransmitters which are released into the synaptic cleft during neurotransmission.

Voltage-Gated Channels

Protein channels in cell membranes that open or close in response to changes in membrane voltage, crucial for nerve impulse transmission.
