Answer:
The tomato is the edible berry of the plant Solanum lycopersicum, commonly known as a tomato plant. The species originated in western South America and Central America. The Nahuatl (the language used by the Aztecs) word tomatl gave rise to the Spanish word tomate, from which the English word
The answer is B.
neutral: OH- = H+
acid: H+ > OH-
base OH- > H+
Answer:
C. THE CONVERSION OF FRUCTOSE 1,6-BISPHOSPHATE to fructose- 6- phosphate is not catalyzed by phosphofructokinase -1, the enzyme involved in glycolysis.
Explanation:
This statement is true as the enzyme involved in this step is FRUCTOSE-1,6-BISPHOSPHATASE.
Gluconeogenesis is the coversion of non-carbohydrate molecules (lactic acid, amino acids, glycerol) through the pyruvic acid into glucose in the cells.
This process takes place mainly in the liver and occurs during periods of fasting, starvation, low carbohydrate diets.
The pathway of gluconeogenesis involves eleven steps of enzymatic catalyzed reactions.
In the conversion of fructose 1,6- bisphosphate to fructose-6-phosphate is catalyzed by fructose 1,6-bisphosphatase and not by phosphofructokinase -1 which is involved in glycolysis. This step is a rate-limiting step of the pathway.
The conversion of glucose-6-phospahte to glucose is not catalyzes by hexokinase but glucose -6- phosphatase.
This is an example of negative feedback.
After a big meal, glucose levels in the bloodstream increases. The body recognises this change and goes through homeostasis, or the regulation of bodily state or internal environment.
The pancreas secretes insulin, which then binds to insulin receptors. This will result in the uptake of excess glucose from the bloodstream into cells and converted into glycogen to be stored in cells as energy storage molecules.
Since there is the counter effect of body (i.e. when blood-glucose concentration increases, the body sends a signal to decrease the blood-glucose concentration, this is called a negative feedback (instead of a positive feedback, which occurs if for e.g. the body signals cells to increase blood-glucose concentration even after blood-glucose concentration increased after a heavy meal).
Hope this helps! :)
Pairs of Chromosomes are called Sex cell pairs. Sex cells, like sperm and egg, have only a set of Chromosomes called "Daughter Cells". Sorry I didn't do all of your questions, I could only find some of the answers.
