The two main variables in an experiment are the independent and dependent variable.
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable.
A dependent variable is the variable being tested and measured in a scientific experiment.
The dependent variable is 'dependent' on the independent variable. As the experimenter changes the independent variable, the effect on the dependent variable is observed and recorded.
For example, a scientist wants to see if the brightness of light has any effect on a moth being attracted to the light. The brightness of the light is controlled by the scientist. This would be the independent variable. How the moth reacts to the different light levels (distance to light source) would be the dependent variable.
When results are plotted in graphs, the convention is to use the independent variable as the x-axis and the dependent variable as the y-axis.
At neutral pH, the ionic group COO- on succinate makes bonds with the active site of succinate dehydrogenase. This bonding is required for succinate oxidation.
<h3>What is
succinate oxidation?</h3>
In the Krebs cycle , succinate dehydrogenase catalyzes the oxidation of succinate to fumarate, with the resulting electrons being supplied to respiratory chain complex III to decrease oxygen and produce water.
SDH oxidizes succinate to fumarate during the citric acid cycle. SDH is structurally similar to fumarate reductase, an enzyme that catalyzes the opposite process during anaerobic respiration in bacteria.

Chromosome is a threadlike structure present in nucleus .Chromosomes are composed of chromatin and carry the genes in a linear sequence; these determine the individual characteristics of an organism there are 23 pairs of chromosomes out of those one is different. In female it is XXY qnd in males it is xy
