Answer:
Anaerobes carry on cellular respiration in the absence of oxygen, whereas aerobes carry on cellular respiration in the presence of oxygen.
Explanation:
Many of the cell processes needed need some energy to occur. Cellular respiration is the process by which cells degrade organic compounds and turn them into energy. Cellular respiration follows two ways, which depend on the presence or absence of oxygen, and both of them begin with the process of glycolysis, which occurs in the cytoplasm and does not need oxygen to occur.
<u>Aerobic Respiration</u>
- Occurs in the presence of free oxygen.
- Series of reactions by which pyruvic acid (product of glycolysis) turns into CO₂ and H₂O, producing many ATP molecules.
- Respiration occurs in the mitochondria.
- Takes place in two steps or stages: Krebs cycle and electron transporter chain.
- Glycolysis and Krebs cycle produce electrons, which then travel along the electron transporter chain while releasing energy, and ATP is produced.
<u>Anaerobic Respiration </u>
- Occurs in the absence of free oxygen
- Series of reactions by which using pyruvate (product of glycolysis) 2 ATP molecules van be produced.
- There are two ways in which anaerobic respiration can be produced: lactic fermentation and alcoholic fermentation.
- Lactic fermentation produces lactic acid and 2 ATP
- Alcoholic fermentation occurs in two steps, and the final products are ethylic alcohol, 2ATP, and 2 CO₂
- The whole anaerobic process occurs outside the mitochondria.
False, it doesn’t depend on environmental factors
1 possible future is The Big Crunch. This theory assumes that the average density of the universe will be enough to stop its expansion and begin contracting.
2. Some theorists state that the expansion of the universe will go on forever, and if that happens, the universe will cool as it expands, and then it will become too cool to sustain life.
3. The Big Rip. The universe may keep expanding, as I mentioned before. But as it expands, the gravity may not be able to hold all the planets together, as it is now. Galaxies would tear apart first, followed by smaller black holes, planets and stars. Eventually, space would start expanding faster than the speed of light, and atoms would start breaking down into super small particles and everything would fall into nothing.
