The stimulation of an inadequate number of sodium channels for the generation of a positive sodium channel feedback loop is cons
diamong [38]

Answer:

Sub-threshold

Explanation:

If the stimulus is too small to generate the action potential, it is considered as subthreshold stimulus. Subthreshold stimulus causes the opening of small number of sodium channel i.e. not enough to generate action potential because action potential is generated by complete reversal of membrane polarity. Slight depolarization is caused by subthreshold stimulus by the opening of inadequate number of sodium channel but its magnitude is not enough to reach the threshold voltage. Consequently the action potential is not generated.

The response produced by subthreshold stimulus is called as local response or local depolarization because it could not travel further. The minimum stimulus required to generate the action potential is call as threshold stimulus and stimulus greater than threshold stimulus is called as suprathreshold stimulus. It changes the frequency of generated action potential.

Place the following events in sequence: A) Food enters your large intestine; B) Food enters your small intestine; C) Food enters
Anarel [89]

Answer:

The correct sequence is

1st step- Option C

2nd step- Option B

3rd step- Option A

Explanation:

Initially, when a person swallows the food, it goes into the stomach through a muscular type of tube which helps in the transportation of food items and liquids from the mouth into the stomach, which is commonly known as the esophagus.

After passing through this tube and reaching the stomach, the liquid and food items mix up with the juice that it produces, and eventually releases its particles into the small intestine. These transported particles are known as chyme.

As the food particles reach the small intestine, its muscles allow the food particles to mix up with the digestive juices that are released from the organs namely liver, pancreas, as well as the intestine and helps in the proper digestion of the food. The walls of the small intestine extracts the nutrients that are digested into the bloodstream, where the blood supplies the nutrients into the remaining parts of the body.

After the food is digested and nutrients are absorbed into the body, the remaining waste products or undigested particles are transported to the large intestine, where it extracts the water and converts the waste particles into the stool, which are later eliminated from the body.

Thus, the correct sequence is arranged above.

Lactose when digested, it is hydrolyzed by lactase into its monomers, which are then absorbed by blood. Following are test resul
kap26 [50]

Answer: Based on the information, the person DOES NOT have lactose intolerance because glucose levels significantly increases in normal individuals after a lactose rich meal.

Explanation:

Lactose is a disaccharide carbohydrate which when taken (found mostly in diary products) is hydrolyzed by lactase into its monomers, which are then absorbed into the blood. The hydrolysis of lactose gives glucose and galactose which is carried out by the digestive enzyme lactase. Deficiency of the lactase enzyme gives rise to a disorder known as LACTOSE INTOLERANCE.

The diagnosis of lactose intolerance or lactase deficiency can be confirmed by measuring the plasma glucose concentrations, as in glucose tolerance test, after giving an oral load of lactose rich solution. If the disaccharide (lactose) cannot be hydrolysed, the constituent monosaccharides cannot be absorbed and the concentrations of plasma glucose rise VERY little.

But the fasting blood glucose done after 2 hours of drinking a lactose rich solution showed a typical rise in blood glucose levels which were 80, 90, 100, 110 and 120 mg/ dL tested for every 30 minutes. This indicates that the individual does not have lactose intolerance because the glucose gotten from hydrolysed lactose was absorbed and cause a significant rise in blood levels.
