Where is the respiratory electron transport system (ETS) located in plants?

1. Mitochondrial matrix

2. Outer mitochondrial membrane

3. Inner mitochondrial membrane

4. Intermembrane space

The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that Adenosine Triphosphate (ATP) is formed because
1. high energy bonds are formed in mitochondrial proteins
2. ADP is pumped out of the matrix into the intermembrane space
3. a proton gradient forms across the inner membrane
4. there is a change in the permeability of the inner mitochondrial membrane toward Adenosine Diphosphate (ADP)

Which of the following statements regarding mitochondria is incorrect?

Respiratory Quotient (RQ) value of tripalmitin is:

Conversion of glucose to glucose-6-phosphate, the first irreversible reaction of glycolysis, is catalyzed by:

The respiratory quotient during cellular respiration would depend on the

1. Nature of enzymes involved

2. Nature of the substrate

3. Amount of carbon dioxide released

4. Amount of oxygen utilized
