Q

What is the Ribosome’s purpose?

A

it constructs and assembles proteins through translation

17
Q

What is the Rough Endoplasmic Reticulum’s purpose?

A

it gives proteins the purpose of inserting into the cell membrane

18
Q

What is the Golgi Apparatus’ purpose?

A

it tags proteins which then sends them to different locations

19
Q

What is the Smooth Endoplasmic Reticulum’s purpose?

A

it folds proteins and regulates calcium

20
Q

What is the Mitochondria’s purpose?

A

to produce ATP

21
Q

What is the Cell Membrane’s purpose?

A

it regulates what goes in and out of the cell

22
Q

What is the Cytoskeleton’s purpose?

A

it allows proteins to “move things along” by crossing it

23
Q

What is the Axon Hillock?

A

it’s the part that meets the body of the neuron

24
Q

What is the Axon Collateral?

A

the branches from the axons

25
Q

What is the purpose of the Presynaptic Terminal?

A

it sends electrical impulses out

26
Q

What is the purpose of the Synaptic Vesicle?

A

it releases the transmitters from the presynaptic terminal

27
Q

What is the purpose of the Postsynaptic Terminal?

A

it received the transmitters from the synaptic vesicle through receptors

28
Q

What are dendrites peppered with?

A

different synapses
