Yes they can Only eukaryotes form multicellular organisms consisting of many kinds of tissue made up of different cell types
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.
Answer: False
Explanation:
Hemoglobin can be defined as red protein that transports oxygen to various parts of the body according to its need.
It does not transports the same amount of oxygen to all the tissues. Some tissues of the body might require more more oxygen and some cells might require less amount of oxygen.
It depends on the state of activity. It transports more oxygen to the tissue that require it the most.
Example: The skeletal muscles of the body require more oxygen and it can be more than 80% .
Hence, the given statement is false and hemoglobin does not releases the same amount of oxygen to each and every tissue of the body.
Carbon, nitrogen, oxygen, hydrogen
No. Below 1000m the sunlight could not reach therefore plant like organism would not be able to grow there. However if the organism does not need sunlight then it might have a small chance of survival. Of course there also is the water pressure that can also pose a problem. So I say No.
