Answer:
When neurotransmitter molecules bind to receptors located on a neuron's dendrites, voltage-gated ion channels open. At excitatory synapses, positive ions flood the interior of the neuron and depolarize the membrane, decreasing the difference in voltage between the inside and outside of the neuron.
Explanation:
Positive ions flow into a neuron and depolarize its membrane when a
neuron is activated.
What is a Neuron?Neurons are also referred to as nerve cells and they help to send and
receive signals from the brain.
Positive ions such as Sodium ions flood the interior of the neuron and
depolarize the membrane, in the excitatory synapse. When this occurs, the
voltage difference between the inside and outside of the neuron is
reduced.

Aerobic respiration is used to create energy when oxygen is available.
Anaerobic respiration is used to create energy when oxygen is not available.
Glycolysis is the process of breaking down a glucose molecule.
Aerobic respiration is a cellular process that occurs in the presence of oxygen. It is the primary mechanism for generating energy in cells and involves the complete breakdown of glucose to produce energy-rich molecules called ATP (adenosine triphosphate). The process takes place in the mitochondria and is highly efficient, producing a large amount of ATP.
Anaerobic respiration, on the other hand, is a metabolic process that occurs when oxygen is not available or in short supply. While it is less efficient than aerobic respiration, it still allows cells to generate ATP without the need for oxygen. One common type of anaerobic respiration is fermentation, which produces lactic acid or ethanol as byproducts.
Glycolysis is the initial step of both aerobic and anaerobic respiration. It is a series of reactions that break down a molecule of glucose into smaller molecules, producing a small amount of ATP in the process. Glycolysis occurs in the cytoplasm of the cell and is the same for both aerobic and anaerobic pathways. In the presence of oxygen, glycolysis is followed by the citric acid cycle and oxidative phosphorylation to produce more ATP through aerobic respiration. In the absence of oxygen, glycolysis may lead to lactic acid fermentation or alcoholic fermentation, depending on the organism.
