If fat acts as respiratory substrates then they would need to be broken down into fatty acids and glycerol. If fatty acids were to be respired they would first be degraded to .... a .... and enter the pathway. Glycerol would enter the pathway after being converted to .... b ....

A

a-pyruvic acid, b-acetyl CoA

B

a- acetyl CoA, b- PGAL

C

a- PGAL, h-acetyl CoA

D

a-acetyl CoA, b-pyruvic acid

Text Solution

Verified by Experts

The correct Answer is:
B
(B) If fat acts as respiratory substrates then they would need to be broken down into fatty acids and glycerol. If fatty acids were to be respired they would first be degraded to acetyl CoA and enter the pathway. Glyc- erol would enter the pathway after being converted to PGAL /triose phosphate /DHAP.

Glycerol would enter the respiratory pathway only after being converted to

Proteins acts as respiratory substrates then they would be degraded by proteases and the individual amino acids (after deamination) depending on their structure would enter the pathway at some stage.

A : Fat breakdown yields fatty acids and glycerol R : Glycerol enters glycolysis through serine formation.

Fat has two components, glycerol and fatty acids. They enter common pathway of respiration as

For entry into the respiratory pathway , fatty acid must convert into

Fats are broken down into glycerol and fatty acids with a series of chemical reactions occurring in the digestive tract. The fatty acids are then absorbed through the small intestine and enter lacteals. The excess of such fatty acids gets converted into fats and are stored in the adipose tissue present in the subcutaneous layer. Under starvation, the fatty acids are mobilized to be used as energy during cellular respiration. These fatty acids during cellular respiration are first broken down into

Assertion: All carbohydrates are usually first converted into glucose before they are used for respiration. Reason: Proteins fats and organic acid can also be respired but they do not enter respiratory pathway at the first step.
