5 Protons increase in number in stroma. Choose the correct answer from the options given below:
Explanation:
Exp:B Chemiosmosis or Chemiosmotic theory is given by Peter Mitchell explains the synthesis of ATP in the chloroplast. - During the process of photosynthesis, the synthesis of ATP causes proton gradient to develop due to the accumulation of protons in thylakoid lumen that are formed by splitting of water. As the electron moves through the photosystem, proton are transported across the membrane. Now NADP reductase (enzyme) in stroma along with the electron acceptor remove protons along with the reduction of NADPH \(+\mathrm{H}^{+}\). - This cause proton gradient across the thylakoid membrane. The ATPase enzyme has a channel which allows the flow of proton through it and during this process the ATP is synthesised. Protein increase in lumen of thylakoid. Primary acceptor of electron transfer its electron to \(\mathrm{H}^{+}\)carrier. Pheophytin acts as the first electron carrier intermediate in the electron transfer pathway of PS-II.

Energy rich macromolecules are digested by the following cell organelle
1 Mitochondrion
2 Lysosome
3 Endoplasmic Reticulum
4 Golgi bodies
Explanation:
Exp:B Lysosome, is a single membrane bound structure found in nearly all type of eukaryotic cells and contains hydrolytic enzyme which is responsible for the digestion of macro-molecules, old cell part etc. It is also called 'suicidal bag of cells'

Lysosomes are \(\mathbf{A}\) dense bodies, and originate from B
Exp:A Lysosome was discovered by de Duve in 1949 biochemically in rat liver homogenate by ultracentrifugation. Single cell membrane organelle - vacuole, E.R, Golgi body, Lysosome. Double membrane - mitochondria, nucleus, chloroplast. Membrane-less cell organelle - Ribosome, centrosome.

(a) Protein
(i) SER
(b) Lipid
(ii) Golgi body
(c) Glycoprotein
(iii) Lysosome
(d) Hydrolytic enzyme
(iv) RER

2 a-iv, b-ii, c-i, d-iii
3 a-iv, b-i, c-ii, d - iii
4 a - i, b - iii, c - ii, d - iv
Explanation:
Exp:C - Rough ER are attached with ribosomes and helps in protein synthesis. - Smooth ER are not connected with ribosome and they are function as lipid formation, detoxification, various hormones and steroid formation. - Golgi bodies function as a modification and synthesis of carbohydrate, which is a major part of Glycoproteins. - Lysosomes contain hydrolytic enzyme helps in degrade various biomolecules.
