Where do the catabolic products of fatty acid breakdown enter into the citric acid cycle?
Darina [25.2K]

Answer:

acetyl-CoA.

Explanation:

Fatty acids are broken down into acetyl-CoA by the process of beta-oxidation inside the mitochondrial matrix part of the powerhouse of the cell. Whereas fatty acids are synthesized from acetyl-CoA in the mitochondria.

Then acetyl-CoA which is produced by beta-oxidation enters the citric acid cycle in the mitochondrion by combining with oxaloacetate to form citrate and then complete the combustion of the acetyl-CoA into carbon dioxide and water.

amid [387]

Answer:

A) Mass = 32 g of KCl

Explanation:

Given data:

Mass of potassium chloride produced = ?

Mass of potassium chlorate = 52 g

Solution:

Chemical equation:

2KClO₃     →       2KCl + 3O₂

Number of moles of KClO₃:

Number of moles = mass/molar mass

Number of moles = 52 g/ 122.55 g/mol

Number of moles = 0.424 mol

Now we will compare the moles of KClO₃ and KCl

             KClO₃      :       KCl

               2            :       2

          0.424         :       0.424

Mass of KCl:

Mass = number of moles × molar mass

Mass = 0.424 mol × 74.55 g/mol

Mass = 32 g

8. Write a balanced chemical equation showing how you could prepare each of the following salts from an
polet [3.4K]

Answer:

according to my reading

use own words

Explanation:

Salts are combinations of acids and bases. The cation comes from a base and the anion from an acid. Therefore, to make KNO3 we react KOH and HNO3. See how that is done? We write K and add OH to make KOH. We take NO3 and add H to make HNO3.
