When your cells use fat for energy, the fatty acids are broken up into molecules of acetyl COA. Predict how many ATP can be made
IgorC [24]

Answer:

12 molecules of ATP can be made from one molecule of acetyl CoA.

Explanation:

If one molecule of acetyl CoA enter TCA cycle then it result in the formation of 3 molecules of NADH,1 molecule of FADH2 and 1 molecule of GTP that is equivalent to 1 molecule of ATP.

                        Now the reducing equivalent such as NADH and FADH2 enters electron transport chain and get oxidized to regenerate NAD+ and FAD along with ATP. 1 molecule of NADH produces 3 molecules of ATP whereas 1 molecule of FADH2 produces 2 molecules of ATP.

               So that net gain of ATP is given below

3 molecules of NADH = 9 molecules of ATP

1 molecule of FADH2 =2 molecules of ATP

1 molecule of GTP = 1 molecule of ATP

As a result total 12 molecules of ATP is by the oxidation of 1 Acetyl CoA  by TCA cycle .

Mendel also wondered if the inheritance of one trait affected the inheritance
svet-max [94.6K]

Answer:

A. dihybrid crosses

Explanation:

A dihybrid cross can be defined as a mating experiment between two lines/varieties/organisms that differ in two phenotypic traits. By using pea plants, Mendel performed dihybrid crosses in order to analyze the mode of inheritance of both phenotypic traits at the same time. From these mating experiments, Mendel observed that the inheritance factors (nowadays called genes) sorted independently from one another in the next generation, which is called the principle/law of Independent Assortment.
