Ich muss Bio Test selbst korrigieren aber komme nicht weiter?
Ich hab bio auf englisch also wenn möglich auf englisch antworten
Das sind die aufgaben :) danke im vorraus ^^

C)
I synaptic vasicle
II ligand-gated ion channel (LGIC)
[receptor for neurotransmitter]
III neurotransmitter
IV mitochondrion
D)
Caffeine primarily influences the neurotransmitter (III) and ligand-gated ion channels (II) at the synapse. It acts as an adenosine receptor antagonist, meaning it blocks adenosine from binding to its receptors. Normally, adenosine inhibits neurotransmitter release, leading to relaxation and drowsiness. However, by preventing this inhibition, caffeine increases the release of excitatory neurotransmitters such as dopamine and norepinephrine, leading to heightened alertness and wakefulness.
Additionally, since neurotransmitters like dopamine and glutamate interact with ligand-gated ion channels, caffeine indirectly enhances their activation. This results in increased neuronal excitability and faster signal transmission. Although caffeine does not directly affect synaptic vesicles (I) or mitochondria (IV), its impact on neurotransmitter release and receptor activity significantly alters synaptic function and overall brain activity.
So hätte ich die Aufgaben gelöst.
Vielleicht hilft es Dir etwas weiter.
