Through which process, phosphoglyceraldehyde is converted into biphosphoglyceric acid?
1 Phosphorylation and oxidation.
2 Dephosphorylation and dehydrogenation.
3 Carboxylation and hydration.
4 Decarboxylation and hydrogenation.
Explanation:
Exp:A Phosphorylation and oxidation cellular respiration is the process of obtaining chemical energy from the breakdown of organic molecules that we consume through food. The $\mathrm{C}-\mathrm{C}$ bonds in the complex molecule undergo oxidation that breaks the bond between them and release lots of energy which the cell traps in the form of ATPs (phosphorylation). Hence, through Phosphorylation and oxidation process, phospho-glyceraldehyde is converted into biphosphoglyceric acid.

Select the wrong statement :
1 When tripalmitin is used as a substrate in respiration, the R.Q. is 0.7
2 The intermediate compound which links glycolysis with Kreb's cycle is malic acid
3 One glucose molecule yields a net gain of 36 ATP molecules during aerobic respiration
4 One glucose molecule yield a net gain of 2 ATP molecules during fermentation
5 The scheme of glycolysis was given by Embden, Meyerhof and Parnas
Explanation:
Exp:B Pyruvic acid formed during glycolysis undergoes oxidative decarboxylation to form acetyl CoA. This 2-carbon acetyl CoA acts as a conneting link between glycolysis and kreb cycle. - Acetyl CoA acts as substrate enters in krebs cycle and the acceptor molecule is oxaloacetate a four carbon compound. Hence, the intermediate compound which links glycolysis with Kreb's cycle is malic acid is incorrect statement.

Cyanide resistant respiration is characteristic of:
1 viruses
2 bacteria
3 plants
4 animals
Explanation:
Exp:C Cyanide resistant respiration is characteristic of plants. - During aerobic respiration is the flow of electron in usual mitochondrial electron transport chain is blocked by the presence of cyanides which inhibit the activity of cytochrome oxidize. This type of activity is known as cyanide sensitive respiration. - Plant mitochondria, however, differ from the animal mitochondria in having an alternate oxidize system pathway through which terminal oxidation of reduced coenzyme continues even in the presence of cyanides. This type of respiration is known as cyanide resistant (or cyanide insensitive) respiration.

Complete oxidation of a molecule of glucose yield :
1 15 ATP molecules
2 36 ATP molecules
3 2 ATP molecules
4 8 ATP molecules
Explanation:
Exp:B Glycolysis is a sequence of 10 chain reactions catalyzed enzymes. 38 molecules of ATP are formed in oxidation of $1 \mathrm{~mol}$ of glucose in aerobic conditions but 2 molecules of ATP are used in during glycolysis, so the net gain is of 36 molecules of ATP. The free energy released in this process in used to produce the high energy molecules ATP and NADPH.
