Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.
Answer:
Aerobic respiration is a process glucose produces energy in the presence of oxygen. In this process glucose is oxidized to produce carbon dioxide, water and energy in the form of ATP.
C₆H₁₂O₆ + 6O₂ = 6CO₂ + 6H₂O + Energy (ATP)
Three main processes that make up aerobic respiration are:
1. Glycolysis: it takes place in the cytosol of the cell. Here, glucose is oxidized to form three carbon molecule pyruvate. This process produces energy in the form of 2 ATP molecules and 2 NADH molecules. These NADH molecules carries 2 energy electrons these electrons are utilized by the electron transport chain.
2. Kreb's cycle: it takes place in the cytoplasm and mitochondria of the cell. Here, the molecules of pyruvate produced during glycolysis is utilized to produce ATP.
3. Electron transport chain: glucose is not entirely converted into ATP. The NADH molecules produce during glycolysis produces 2 energy electrons these electrons are taken up by electron transport chain in the mitochondria inner matrix. A proton gradient develops across the matrix after donation of electrons to electron transport chain. This gradient in turn produces energy in the form of ATP.
<h2>Answer:</h2>
The correct options are 1,4 and 5. By looking at phylogenetic tree we can conclude this;
1. Species A and C may have shared features from a common ancestor.
4. Species B and E may have shared features from a common ancestor.
5. Species A is more related to species B than species B is related to species C
