Mark the given statements True (T) or False (F).

(i) The breaking of C-C bonds of complex cells, leading to release of considerable amount of energy is called respiration. The compounds that are oxidized during this process are known as respiratory substrate.

(ii) ATP acts as the energy currency of the cells.

(iii) Plants have specialized organs for gaseous exchange and they have stomata and lenticles for this purpose.

(iv) The breakdown of glucose to pyruvic acid is called glycolysis.

(v) The scheme of glycolysis was given by Embden, Meyerhof and Parnas and is often referred to as the EMP pathway.

(vi) Glycolysis occurs in cytoplasm of cell whereas citric acid cycle occurs in mitochondria membrane.

(vii) In plants, glucose is derived from sucrose which is end product of photosynthesis.

(viii) In glycolysis, a chain of 10 reaction occurs.

(ix) Glycolysis starts with one molecule of six-carbon compound glucose and ends in formation of 3 moleucles of 2-Carbon compound pyruvic acid.

(x) In all cells of animals, when oxygen is inadequate, pyruvic acid is converted to lactic acid by enzyme lactate dehydrogenase.

(xi) Pyruvic acid + CoA + 🡪 🡪 AcetylCoA + CO 2 + NADH + Above reaction is catalyzed by enzyme pyruvate dehydrogenase, which requires presence of ion.

(xii) During the conversion of succinyl-CoA to succinic acid in citric acid cycle, a molecule of GTP is synthesized. This is a substrate-level phosphorylation.

(xiii) In Mitochondrial matrix, 4 mol of NADH, 1 mol of FADH 2 and 1 mol of ATP is synthesized from 1 mol of pyruvate.
