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 .

4- Jamie does an experiment. She charges a pencil by rubbing it with a piece
lyudmila [28]

Answer:

More info given below.

Explanation:

This attraction occurs as a result of static charge. You see an atom is referred to as the smallest particle of a substance; and when an atom gains or looses electrons it becomes unstable creating a difference in potential. However in this case rubbing induces friction which induces heat. This heat excites the atom to loose electrons creating a negative charge on the silk and a converse positive charge on the pencil.
