A neuron transmits information by the secretion of hormones. True or False

grandymaker [24]

Answer:

The given statement is false.

A neuron is the basic structural and functional unit of the nervous system. It helps in transmitting information from one neuron to another neuron, gland, or muscle cell.

The conduction of nerve impulse is electrochemical in nature. It transmits the impulse electrically through the axon the nerve cells and chemically through synapses (gap between two nerves cells).

The axon terminals of pre-synaptic nerve cell release chemical messengers (also called neurotransmitters) in the synaptic cleft. These messengers then bind to the receptors present on the post-synaptic nerve cell and regenerate the nerve impulse.

During which process is ethanol produced?

Kipish [7]

Answer:

Alcohol fermentation

Explanation:

When oxygen availability is low, the cell can't perform aerobic respiration to breakdown glucose. Instead, anaerobic respiration must be performed. This occurs in cells which consume large amounts of energy, such as muscle cells. Anaerobic respiration produces much less energy than aerobic respiration

One type of anaerobic respiration formed by yeast is called alcohol fermentation (also called ethanol fermentation). This begins with glycolysis, where one molecule of glucose is broke down into 2 molecules of pyruvate. The energy from this reaction generates 2 molecules of ATP, and converts NAD+ to NADH.

Then, the two molecules of pyruvate are further broke down into 2 acetaldehydes (releasing two molecules of carbon dioxide as a by-product). These two molecules of acetaldehyde are then converted into tw molecules of ethanol, using the H ions from NADH, converting it back to NAD+. See the attached picture

This process is taken advantage of to brew beer and wine.
