Which of the following statements regarding mitochondria is incorrect?
1 Enzymes of electron transport are embedded in outer membrane.
2 Inner membrane is convoluted with infoldings.
3 Mitochondrial matrix contains single circular DNA molecule and ribosomes.
4 Outer membrane is permeable to monomers of carbohydrates, fats and proteins.
Explanation:
Exp:A The enzymes of the electron transfer chain are embedded in the inner membrane of the mitochondria. The inner membrane is convoluted with infolding to increase its surface area. The outer membrane is permeable to monomers of carbohydrates, fats, and proteins for transport into the mitochondria through protein channels called porins.

The overall goal of glycolysis, Krebs cycle and the electron transport system is the formation of:-
1 Nucleic acids
2 ATP in small stepwise units
3 ATP in one large oxidation reaction
4 Sugars
Explanation:
Exp:B Respiration is an energy liberating, enzymatically controlled multistep catabolic reaction. In this process step wise break down of organic substances (hexose sugar) takes place inside the living cell. 3 major process occur in aerobic respiration- glycolysis, kreb's cycle and electron transport chain. The substrate is completely broken down to form $\mathrm{CO}_{2}$ and water and a large amount of energy is released stepwise in the form of ATP. Hence, the overall goal of glycolysis, Krebs cycle and the electron transport system is the formation of ATP in small stepwise units.

Which of the following respiratory substrate requires the highest number of $\mathrm{O}_{2}$ molecules for its complete oxidation?
1 Tripalmitin
2 Triolein
3 Tartaric acid
4 Oleic acid
Explanation:
Exp:B Triolein - Triolein is a respiratory substrates which requires highest number of ATP molecule for its complete oxidation. It is a symmetrical triglyceride which is derived from 3 units of unsaturated fattyacid chain linked with a molecule of glycerol. - Tripalmitin-Triglycerides such as tripalmitin, trilaurin, tricaprin and trimyristin are used for constructing the internal lipid core. - Tartaric acid-Tartaric acid is often used as an acidulant in grape and lime-flavored beverages, gelatin desserts, jams, jellies, and hard sour confectionary. - Oleic acid - Oleic acid is a type of fatty acid. Oils with oleic acid are used to replace saturated fats in the diet.

Salt respiration is:
1 secretion of salt through respiratory channels
2 decrease in respiration during salt absorption
3 active increase in respiration during mineral absorption
4 linking of ion movement with respiratory chain
Explanation:
Exp:C Salt Respiration :- It is the increase in the rate of respiration of a plant or tissue when it is transferred from water to a salt solution. Saline water contains $\mathrm{Na}^{+} \& \mathrm{Cl}^{-}$ions. These ions move from lower concentration to higher concentration (against the concentration gradient). In this way salt respiration requires more energy. Hence, Salt respiration is active increase in respiration during mineral absorption.
