In 1665, Robert Hooke observed D. Cell Walls through a microscope!
Particles in a solid are tightly and closely packed together. They do not move. For example rock, wood etc.
Particles in a liquid are loosely packed as compared to solids.They move or slide slowly. For example water.
Particles in gases are very loosely packed and freely move and float. For example oxygen.
The students will have to model their marbles accordingly. For solids they will have to put the marbles together in a cluster. For showing liquids, they will have to arrange marbles with slight gaps between them. For showing gases, they will have to arrange the marbles sparsely and scatter them in the box.
Answer:
The correct answer will be option-
1. Each turn of the Citric Acid Cycle requires two molecules of Acetyl-CoA
Explanation:
Citric acid cycle or Krebs cycle is the cyclic set of reaction taking place in the matrix of the mitochondria and associated with the production of reaction intermediates utilized in the production of the ATP molecules in the cellular respiration.
Citric acid cycle converts two molecules of Acetyl-CoA as two Acetyl-CoA are produced from pyruvate through pyruvate decarboxylation per glucose molecule.
Since the citric acid cycle is a part of the aerobic cellular respiration although oxygen is not utilized therefore it is considered an aerobic process.
Each turn of the Citric acid cycle produces one molecule of GTP, 3 NADH and 2 molecules of carbon dioxide but it does not form Coenzyme A molecule instead CoA is used and attached to Acetyl group.
Thus, the selected options are the correct answer.
