This proces produces Oxygen, ATP, and NADPH. Another photosynthetic process involves the production of sugar (eg. CHO ) from Carbon Diocide. This process is known as the Calvin gyde, and it uses ATP, NADPH and several enzymes. Photosynthesis has 2 important stage(s) that are described as & the Light dependent stage & the Light-independent stage Gall the above none of the above 80. If a molecule has been Reduced during a reaction, it has lost electrons and hydrogens. Tor F

Answer 1

46. Option D is correct all the above.

ATP or Adenosine triphosphate is an energy rich molecule produced by our body during the cellular respiration.

Each ATP molecule is consists of

1. Nitrogenous base Adenine.

2. A five carbon ribose sugar.

3. A triphosphate

47. True

Removal of the terminal phosphate from ATP generates 30.5KJ of energy per mole.

48.Option B is correct

Aerobic respiration involves complete oxidation of glucose into carbon dioxide and water.
Glucose breakdown or glycolysis begins in the cytoplasm that leads to the formation of two molecules of pyruvate. Pyruvate enters the mitochondria and participates in the Krebs cycle which takes place in the mitochondrial matrix. Eventually electron transport chain generates proton gradient for the formation of ATP through ATP synthase.

49. False

Glycolysis, Krebs cycle and electron transport chain only occur during the aerobic respiration. Since fermentation takes place in the absence of oxygen, it only involves glycolysis.

50. True

Electron transport chain accepts electrons from NADH and FADH2.

51. ATP synthase uses proton gradient to make ATP from ADP.

52. True

Terminal electron acceptor of electron transport chain is oxygen.

53. True

Nitrate or sulphate can be used as electron acceptor.

54. False

Carbon dioxide is released during oxidative decarboxylation and Krebs cycle.
55. True

Anaerobic respiration utilises molecules like nitrates, sulfate or sulfur, as electron acceptor rather molecular oxygen.

56. False

Fermentation is not a complete oxidation of glucose.

57. True

Amphibolic pathways involves both catabolism and anabolism.

58. True

59. All the above

60. False

Reduced molecules gain electrons and hydrogen.

61. All the above
