Researchers investigating the regulation of neurotransmitter release from presynaptic neurons proposed a model in which CDK5, a

protein expressed in axon terminals, inhibits the movement of synaptic vesicles to the presynaptic membrane... to test their model, the researchers used a modified version of green fluorescent protein...based on the model, which of the following best explains why a bright green fluorescence was observed following stimulation of a presynaptic neuron?

Answer:

"GFP contained in synaptic vesicles moved into the synaptic cleft by exocytosis."

Explanation:

Synaptic vesicles are small membrane sacs that carry neurotransmitters from the cell body where they are produced, to the presynaptic membrane of the terminal button where they are released. The release zone of the presynaptic membrane contains voltage-dependent calcium channels. When an action potential depolarizes the presynaptic plasma membrane, Ca^{2+}-channels open, and  Ca^{2+} flows into the nerve terminal to trigger the exocytosis of synaptic vesicles, thereby releasing their neurotransmitters into the synaptic cleft

What is the appropriate dose of 1:10,000 (0.1 mg/ml) concentration of epinephrine for endotracheal administration to a baby weig
vlada-n [284]
I believe the appropriate dose will be 1.5 mL, 
Epinephrine is used for both allergic reaction and heart attacks, in an effort to increase blood flow through veins and to reduce swelling in airways. When epinephrine is recognized by receptors on smooth muscles, it causes airway-blocking muscle constriction to subside. Other drugs that may be administered by the endotracheal route include atropine sulfate, lidocaine hydrochloride, naloxone hydrochloride, and metaraminol bitartrate.

What structures work in antagonistic pairs to move bones?
Olegator [25]

Answer

Option C - Skeletal Muscles

Explanation

Antagonistic pairs are the muscles that are functionally opposite, if one produces flexion, then the other's primary action is an extension. Skeletal muscles work in pairs to move a bone so that the muscles can function properly. They contract the bone making nerves deliver a message to the brain. For example. Biceps and triceps. The lower arm is moved upwards when the biceps muscle contracts and the triceps muscle is relaxed and vice versa.
