Answer:
The correct answers are: Neurotransmitter Vesicles, Acetylcholine, Contraction.
Explanation:
- At the neuro-muscular junction, impulses are transmitted in the following manner:
- The impulse is carried by an action potential (variable opening and closing of different ion channels located on the membrane of the neurons allowing variable ion movement) to the neuron at the neuro-muscular junction.
- The action potential causes the opening of the voltage dependent calcium channels in the axon terminal of the neuron allowing the entry of calcium ions.
- This causes the neurotransmitter vesicles containing the neurotransmitter acetylcholine to fuse with the pre-synaptic membrane.
- Acetylcholine is released by the method of exocytosis into the synaptic cleft.
- The acetylcholine molecules bind to the the cognate receptors present in the membrane of the muscle cell (sarcolemma).
- This causes the flow of sodium ions into and potassium ions out of the muscle cell, which generates action potential in the muscle cell.
- This action potential causes the muscle cell to contract.
Answer:
In summary, during cellular respiration, most electrons travel the following “downhill” route: glucose → NADH → electron transport chain → oxygen.
Explanation:
Answer:
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2.
Explanation:
This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products
