All of the above answers support the endosymbiotic theory in some way
Answer:
a. Osteogenic cells can differentiate into osteoclasts
Explanation:
Osteoblasts are the cells that are formed from osteogenic cells. The osteogenic cells enter the process of bone formation. There is a secretion of organic compounds and salts to form osteoblast. Osteoclasts are the very large cells that are formed when many monocytes fuse together and are concentrated in endosteum. Osteoclasts are the cells responsible for bone resorption.
Glycolysis uses 2 ATP and produce 4ATP. So the net gain is true.
Oxygen is used in the Electron Transport Chain as the final electron recipient from complex 4 cytochrome a₃.
Explanation:
Glycolysis is the process which is common in all forms of respiration where glucose is metabolized into pyruvate. This process is very essential to continue the next steps of different respiration. Glycolysis requires 2 molecules to process substrate level phosphorylation to convert glucose to glucose 6 phosphate and fructose 6 phosphate to fructose 1, 6 bisphosphate. But it produces 4 ATPs. Thus net gain is 2ATP.
In ETC, the hydrogen carriers NADH and FADH gives off the hydrogen to reduce the complex 1 and 2 respectively and itself gets oxidized. Thus the electron given off is transferred between 4 complexes to finally give off to oxygen to form water.
It was the theory that an organism could form from something such as mud for an example.
