Question-1

Which of the following processes make direct use of oxygen?

(a) Fermentation

(b) Glycolysis

(c) Electron transport

(d) Krebs citric acid cycle

Question-2

In TCA cycle the conversion of succinyl Co-A to succinic acid requires

(a) Co-A + GTP + iP

(b) Acetyl Co-A + GTP + iP

(c) Acetyl Co-A + GDP + iP

(d) GDP + iP

Question-3

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

(a) respirometer

(b) auxanometer

(c) potometer

(d) manometer

Question-4

What is the function of molecular oxygen in cellular respiration?

(a) It combines with glucose to produce carbon dioxide.

(b) It causes the breakdown of citric acid.

(c) It combines with carbon from organic molecules to produce carbon dioxide.

(d) It combines with hydrogen from organic molecules to produce water.

Question-5

The major reason that glycolysis is not as energy productive as respiration is that

(a) it does not take place in a specialized membrane-bound organelle.

(b) $NAD^{+}$ is regenerated by alcohol or lactate production, without the high-energy electrons passing through the electron transport chain.

(c) it is the pathway common to fermentation and respiration.

(d) pyruvate is more reduced than $CO_{2}$; it still contains much of the energy from glucose.
