Answer: 17
The atomic number is the number of protons, neutrons, or electrons a cell has in its original form
Answer:
From the point of view of the type of molecule that is obtained after the degradation of the hydrocarbon skeleton, amino acids can be classified as: glucogenic and ketogenic. The main difference between glucogenic amino acids and ketogenic amino acids is that glucogenic amino acids can be converted to pyruvate or other glucose precursors, while ketogenic amino acids can be converted to acetyl CoA and acetoacetylCoA.
Explanation:
Glucogenic amino acids are amino acids that break down to pyruvate, alpha-ketoglutarate, succinyl Co-A, fumarate, and oxaloacetate and are so named because the synthesis of glucose from these molecules is feasible. Both pyruvate and the Krebs cycle intermediates noted above can be converted to phosphoenolpyruvate and subsequently glucose through gluconeogenesis.Ketogenic amino acids are the amino acids that generate acetyl-CoA or acetacetyl-CoA and are called by this name because they can cause ketone bodies. Since mammals lack the proper enzyme system, these compounds can never be used as precursors for glucose biosynthesis. Of the twenty universal amino acids, fourteen are purely glucogenic and two are purely ketogenic (leucine and lysine). The remaining four (isoleucine, phenylalanine, tryptophan and tyrosine) are glucogenic and ketogenic simultaneously since a part of the hydrocarbon skeleton originates precursors for the biosynthesis of glucose (pyruvate or Krebs cycle intermediates) and the other part acetyl-CoA or acetacetyl -CoA.
They can distinguish whether the entity is living or non living by checking whether they have all the seven characteristics of living things.
These 7 characteristics include:
Movement
Respiration
Sensitivity
Growth
Reproduction
Excretion
Nutrition.
If the entity does show all these seven characteristics, it should be a living organism.
In the past, scientists by using these 7 characteristics, they sorted living things in 5 kingdoms(plus virus), each with their own other characteristics.
The 2.5% solution is said to be Hypertonic to the cellular concentration. A hypertonic solution is one that has a bigger solute concentration outside of the cell, which mean the cell will loss water due to the osmosis process.
