The carboxylation of pyruvate by pyruvate carboxylase occurs at a very low rate unless acetyl-CoA, a positive allosteric modulat

or, is present. If you have just eaten a meal rich in fatty acids (triacylglycerols) but low in carbohydrates (glucose), how does this regulatory property shut down the oxidation of glucose to CO₂ and H₂O but increase the oxidation of acetyl-CoA derived from fatty acids?

Answer:

The mechanism shut down the oxidation of glucose to CO2 and H2O but increases the oxidation of acetyl CoA derived from fatty acids by Tri carboxylic acid cycle.

Explanation:

When a person eat meal rich in fatty acid,the ingested fatty acid will undergo breakdown to form large amount of acetyl CoA.The so formed Acetyl CoA  undergo oxidation by TCA cycle to generate CO2 and H2O.

   on the other hand when a person has eaten a meal that is low in carbohydrates(glucose),at that time less glucose molecule will undergo glycolysis and oxidative de carboxylation to form less amount of acetyl CoA.The acetyl CoA accumulates rather than going further oxidation.

   As the meal contain  low amount of glucose after a certain period of time the glucose level will be depleted.So to maintain homeostasis of body glucose level the gluconeogenesis process is stimulated.

 The conversion of pyruvate to oxaloacetate,one of the most important reaction of gluconeogenesis is boosted by the  high cellular level of  accumulated acetyl CoA.

Help me!! Suppose you must design an experiment to test how a paper airplane's shape affects the distance it will fly. Your plan
Mandarinka [93]

Explanation:

Make a standard, "dart" design paper airplane

Fold your paper into the basic dart paper plane. Fold carefully and make your folds as sharp as possible, such as by running a thumbnail or a ruler along each fold to crease it. Do not bend up the edge of the wings

Throw the plane at least four more times. Each time before you throw the plane, make sure it is still in good condition (that the folds and points are still sharp). When you toss it, place your toe on the line and try to launch the plane with a similar amount of force, including gripping it at the same spot.

Once you have a good idea of how far your plane typically flies, change the plane’s shape to increase how much drag it experiences. To do this, cut slits that are about one inch long right where either wing meets the middle ridge. Fold up the cut section on both wings so that each now has a one-inch-wide section at the end of the wing that is folded up, at about a 90-degree angle from the rest of the wing.

Make paper planes that are different sizes and compare how well they fly.

Try making paper planes out of different types of paper, such as printer paper, construction paper and newspaper. Use the same design for each.

Some people like to add paper clips to their paper planes to make them fly better. Try adding a paper clip (or multiple paper clips) to different parts of your paper plane (such as the front, back, middle or wings) and then flying it
