Answer
As both the neurotransmitters i.e " Dopamine and Glutamate are of excitatory type that increases/enhances the action potential.
As caffeine blocks the action of adenosine and adenosine is known to inhibit Dopamine and Glutamate.
So if Caffeine inhibits adenosine then it must be enhances or increasing the action potential because caffeine ablolishes the inhibitory action of adenosine on excitatory neurotransmitters thus it will increase action potential.
Option A is correct i.e " An increase in action potential".
Add Answer to:
Caffeine blocks the neurotransmitter adenosine from attaching to receptors. Adenosine inhibits dopamine and glutamate. So caffeine...

Which of the following would be an effect of consuming caffeine in your morning coffee? [Select all that apply] A. Adenosine cannot bind its receptor B. Adenosine cannot induce its inhibitory effects on the post-synaptic neuron C. Excitatory effects on the post-synaptic neuron, due to the lack of inhibitory effect of adenosine on the post-synaptic neuron D. More action potentials on the post-synaptic neuron, leading to increased alertness

b) (10 points) Acetylcholinesterase is a hydrolase that
hydrolyzes the neurotransmitter acetylcholine. Caffeine inhibits
the action of Acetylcholinesterase and clinical studies have
indicated that it can be involved in the slowing of Alzheimer
disease pathology. P11149 is a galanthamine analogue that has also
been studied as a potential drug for treating Alzheimer
disease.
The initial reaction rate for acetylcholine hydrolysis was measured
at an enzyme concentration of 5×10-8 M with no inhibitor present,
and in the presence of caffeine or...

The Brain on Mind Altering Drugs Psychoactive drugs alter brain function by acting at synapses in the brain, where they may mimic, enhance, or block the effects of natural signaling molecules (neurotransmitters). The neurotransmitter dopamine plays a particularly important role in creating the dependency aspect of both drug and behavioral addictions. Natural behaviors which enhance survival and/or reproduction, such as eating or engaging in sex, result in a surge of dopamine. Normally, this response helps individuals learn to repeat beneficial...

Two neurons, A and B, synapse onto a third neuron, C. If neurotransmitter from neuron A opens ligand-gated channels permeable to sodium (Na) ions, and neurotransmitter from neuron B opens ligand-gated chloride (CI") channels, which of the following statements is true? Hint: Drawing a simple diagram may help visualize this scenario. Select one: a. An action potential in neuron A causes a depolarizing EPSP in neuron B. b. An action potential in neuron B causes a depolarizing EPSP in neuron...

Part Uncle Mel suffers from depression and is having trouble sleeping. Some medications can increase the amount of neurotransmitter in the synapse by preventing its re-uptake into the presynaptic neuron or its degradation. This increases the level of the neurotransmitter in the synapse and prolongs its effects. Select which neurotransmitters you think might be a good target for anti-depressant drugs. Glutamate O GABA Serotonin Endorphins Dopamine Norepinephrine Submit Request Answer to Part D Prescription medications are designed to induce a...
