Respiration in Plants

283644 Cristae help in:

1 respiration

2 photosynthesis

3 transpiration

4 guttation

Explanation:

Exp:A Mitochondria is a double membrane bound cell organelles.
(i) outer membrane
(ii) inner membrane
The inner membrane folds inside and increase the surface area by forming finger like projection called cristae, which help in respiration. Cristae have 2 faces
(i) Towards matrix side $- N$ face
(ii) Cytosolic side $- P$ face
ATP synthases is an enzyme complex found in inner membrane of mitochondria.

Respiration in Plants

283645 Consider the following statements with respect to respiration.
a. Glycolysis occurs in the cytoplasm of the cell
b. Aerobic respiration takes place within the mitochondria
c. Electron transport system present in the outer mitochondrial membrane
d. $C_{51} H_{98} O_{6}$ is the chemical formula of Tripalmitin - a fatty acid
e. Respiratory quotient
$\frac{Volume of O_{2} evolved}{Volume of {CO}_{2} consumed}$
Of the above statements

1 a, b and d alone are correct

2 b, c and d alone are correct

3 c, d and e alone are correct

4 b, d and e alone are correct

5 a, c and e alone are correct

Explanation:

Exp:A Electron transport system is present in the inner membrane of mitochondria.
- The electron transport chain is a series of complexes made up of proteins and organic molecules in the inner membrane of the mitochondria. The electron are transported from $NADH + H^{+}$ and ${FADH}_{2}$ to molecular oxygen through the complexes of the ETC.
- Tripalmitin $(C_{51} H_{98} O_{6})$ - is triglyceride derived from palmitic acid, a common fatty acid.
- Respiratory quotient (R. Q) - R.Q is the ratio of volume of carbon dioxide liberated in respiration to the volume of oxygen consumed in it over specific period of time by a unit tissue, called organ or organisms.
$R.Q = \frac{Volume of {CO}_{2} liberated}{Volume of O_{2} consumed}$

Respiration in Plants

283646 When malic acid is the respiratory substrate

1 the amount of carbon dioxide released is more than the oxygen consumed

2 the amount of carbon dioxide released is less than the oxygen consumed

3 the amount of carbon dioxide released is equal to oxygen consumed

4 carbon dioxide is not released

Explanation:

Exp:A When malic acid is respiratory substrate: Then the value of R.Q is more than 1 (more than unit.)
$2 C_{4} H_{6} O_{5} + 3 O_{2} ⟶ 4 {CO}_{2} + 3 H_{2} O$
$Malic acid$
$∴ R . Q = \frac{4}{3} = 1.33 (> 1)$
Hence, the amount of carbon dioxide released is 1.33 times more than the oxygen consumed when malic acid is a respiratory substrate.
