The changing quantities in an experiment are called variables. A variable refers to any trait, factor, or a condition, which can prevail in distinct amounts or kinds. An experiment generally exhibits three kinds of variables: independent, dependent, and controlled.
The independent variable refers to the one, which is modified. On the other hand, the dependent variable is implied to observe that how it reacts with the change made to the independent variable. The controlled variables refer to the quantities, which one wants to remain constant.
In the given case, that is, heating a cup of water to witness that whether the sugar will get more easily dissolve. In this, the independent variable refers to the temperature of the water determined in degrees Centigrade. The dependent variable refers to the amount of sugar, which dissolves completely measured in grams.
In this, the controlled variables are stirring and type of sugar. As more stirring might elevate the amount of sugar that dissolves, and different kind of sugars might dissolve in distinct concentrations. So, in order to make sure a fair test, there is a need to keep these variables similar for each cup of water.
In the citric acid cycle, the acetyl group of each molecule of acetyl-CoA is converted into two molecule of carbon dioxide and water. It is the pathway that connects carbohydrates ,fat and protein metabolism.
The cycle which carried out by eight enzymes that completely oxidase acetate by which two carbon molecules in the form of acetyl -CoA into two carbon dioxide and water molecules.6- carbon glucose molecule is split into two 3- carbon molecules called pyruvate , which needs in order to create acetyl CoA.
Citric acid cycle is also known as krebs cycle or TCA cycle it is the series of chemical reactions to release to releases stored energy through the oxidation of acetyl-CoA from carbohydrate, fats and protein.
