LESSON 23, 24 & 25

Question 1 of 10

1

ATP is produced during lipolysis

Select one of the following:

  • True
  • False

Explanation

Question 2 of 10

1

Which of these enzymes is regulated in the lipolysis of the TAG of adipose tissue?

Select one of the following:

  • ATGL (Adipose triglyceride tissue)

  • HS lipase (Hormone sensitive lipase)

  • MAG (Monoacylglyceride)

  • Adenylate cyclate

  • Lipoprotein lipase

Explanation

Question 3 of 10

1

Only in a fasting state HS lipase is phosphorylated by PKA

Select one of the following:

  • True
  • False

Explanation

Question 4 of 10

1

In mitochondrial ß-oxidation we obtain energy in the form of ATP, NADH, FADH2 and if it is a complete oxidation we obtain CO2

Select one of the following:

  • True
  • False

Explanation

Question 5 of 10

1

Which of these statements is not true?

Select one of the following:

  • In the reaction between one fatty acid and one molecule of CoA 2 ATP are required

  • AcylCoA must be transformed into acyl-carnitine to be transferred to cytosol thanks to one enzyme called CPT1

  • In the third part of mitochondrial ß-oxidation AcylCoA loses 2C atoms each step

  • One FADH2 is generated when a double bond is created between the Carbon-α and Carbon-ß of the AcylCoA

  • More energy is produced with a fatty acid of 6C atoms than glucose

Explanation

Question 6 of 10

1

Select one of the following:

  • 35 NADH and 146 ATP

  • 51 NADH and 146 ATP

  • 35 NADH and 148 ATP

  • 51 NADH and 148 ATP

  • Any of these

Explanation
