Current Question (ID: 11549)

Question:

Which of the following statements is incorrect? (1) Glucose is the favoured substrate for respiration (2) All carbohydrates are usually first converted into glucose before they are used for respiration (3) Other respiratory substrates are also respired but they do not enter the respiratory pathway at very first step (4) Fats directly enter the respiratory pathway

Options:

1. Glucose is the favoured substrate for respiration
2. All carbohydrates are usually first converted into glucose before they are used for respiration
3. Other respiratory substrates are also respired but they do not enter the respiratory pathway at very first step
4. Fats directly enter the respiratory pathway

Solution:

Fats directly enter the respiratory pathway. Fats are first broken down into glycerol and fatty acids, which then enter the respiratory pathway at different steps. Glycerol enters as DHAP, which is converted to PGAL, while fatty acids enter as acetyl CoA.
