Oxygen has a partial negative charge, whereas hydrogen had a partial positive charge.
This means that water molecules are polar and can be used to dissolve a lot of chemicals, that's why water is such a popular solvent.
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 .
Answer:
D

The porcupine is a rodent with an unusual trait. Porcupines have sharp spines or quills that help protect it against its predators. This trait is different from other rodents because of its needle like quills. This animal is also similar to that of a hedgehogs.
