[#576] Synthesis of ADP + Pi ⟶ ATP in grana photosynthesis
Correct Answer

(B) Photophosphorylation

Explanation

Solution: The synthesis of ADP + Pi ⟶ ATP in grana photosynthesis is Photophosphorylation. In the process of photosynthesis, the phosphorylation of ADP to form ATP using the energy of sunlight is called photophosphorylation. In photophosphorylation, light energy is used to pump protons across a biological membrane, mediated by the flow of electrons through an electron transport chain. This stores energy in a proton gradient. As the protons flow back through an enzyme called ATP synthase, ATP is generated from ADP and inorganic phosphate.

[#577] Which one is photophosphorylation?
Correct Answer

(B) ADP + Inorganic phosphate ATP

Explanation

Solution: ADP + Inorganic phosphate ATP is photophosphorylation. In photophosphorylation, light energy is used to pump protons across a biological membrane, mediated by the flow of electrons through an electron transport chain. This stores energy in a proton gradient. As the protons flow back through an enzyme called ATP synthase, ATP is generated from ADP and inorganic phosphate.

[#578] Which of these is a unicellular fungi?
Correct Answer

(A) Saccharomyces

Explanation

Solution: Saccharomyces is a unicellular fungus. Saccharomyces is a genus of fungi that includes many species of yeasts. They are unicellular and saprotrophic fungi. Saccharomyces cerevisiae, also known as baker's yeast, is a unicellular fungus that is used to make bread and other wheat-based products.

[#579] Maximum amount of energy/ATP is liberated on oxidation of
Correct Answer

(A) Fats

Explanation

Solution: The maximum amount of energy/ATP is liberated on oxidation of Fats. Fatty acid oxidation is the mitochondrial aerobic process of breaking down a fatty acid into acetyl-CoA units. The end products of fatty acid oxidation include acetyl-CoA, FADH 2 , NADH, water and one acyl-CoA chain that is two carbons shorter. The acetyl-CoA enters the Krebs or citric acid cycle with FADH 2 and NADH to yield ATP (adenosine triphosphate), which is used for energy.

[#580] Application of potash increases
Correct Answer

(C) Disease resistance in plants

Explanation

Solution: The application of potash increases disease resistance in plants. Potash increases disease resistance, drought tolerance, and plumpness of grain and seed, and improves stem rigidity and cold hardiness. The application of potash enhances the firmness, texture, flavor, size, and color of fruit crops, and increases the oil content of oil crops.
