Question

Respiratory quotient for three different substrates was calculated and tubulated as shown here.

Substrate	R.Q.
X Y Z	0.9 1 1.3

Identify X, Y and Z and select the correct option regarding them.

• A. X - Protein, Y - Fats, Z - Glucose
• B. X - Glucose, Y - Protein, Z - Organic acid
• C. X - Protein, Y - Glucose, Z - Organic acid
• D. X - Organic acid, Y - Protein, Z - Fats

Answer 1

The correct option is C X - Protein, Y - Glucose, Z - Organic acid

Respiratory quotient if the protein is 0.8-0.9

For glucose- 1

For organic acids -1.3

So, the correct option is 'X - Protein, Y - glucose, Z - organic acids'.
