CHAPTER 14: RESPIRATION IN PLANTS

 In mitochondria, protons accumulate in the

Terminal cytochrome of respiratory chain which donates electrons to oxygen is

How many ATP molecules are produced by aerobic oxidation of three molecules of glucose

Poisons like cyanide inhibit Na ⁺ efflux and K ⁺ influx during cellular transport. This inhibitory effect is reversed by an injection of ATP. This demonstrates that

Apparatus to measure rate of respiration and R.Q. is

Refer the given equation and answer the question.

2(C₅₁H₉₈O₆ ) + 145O₂ à102CO₂ + 98H₂ O + Energy

The R.Q of above reaction is

Which of the following statements (i to v) regarding glycolysis are correct.

(i) It is ten enzymatic reactions that convert a six-carbon molecule to a three carbon pyruvate and result in a net gain of 2 ATP molecules.

(ii) Glucose undergoes partial oxidation to form one molecule of pyruvic acid.

(iii) Glucose is phosphorylated to give rise to glucose – 6 – phosphate by the activity of the enzyme phosphofructokinase.

(iv) The scheme of glycolysis was given by Gustav Embden, Otto Morrison, and J. Parnas and is often referred to as the EMP pathway.

(v) ATP is utilized at two steps: first in the conversion of glucose into glucose 6- phosphate & second in the conversion of fructose – 6- phosphate to fructose 1, 6-disphosphate

Which of the metabolites is common to respiration mediated breakdown of fats, carbohydrates and proteins?

In which one of the following processes CO 2 is not released?

The chemiosmotic coupling hypothesis of oxidative phosphorylation proposes that adenosine triphosphate (ATP) is formed because

Energy for ATP synthesis is obtained by

The enzymes hexokinase which catalyses glucose to glucose-6-phosphate in glycolysis is inhibited by glucose-6-phosphate. This is an example of
