Answer:
Prokaryotic cells are more simple and smaller than eukaryotic cells. Prokaryotic cells are structurally more simple because of their small size. It's also defined as the smaller a cell size, the greater is its surface to volume ratio (means surface area of a cell compared to its volume).
In smaller prokaryotic cells, a large surface to volume ratio is present. It means that nutrients can rapidly and easily reach any interior part of the cell.
The large eukaryotic cell have limited surface area as compared to its volume it means that nutrients cannot rapidly reach to all interior parts of the cell, because of that eukaryotic cells are more complex than prokaryotic cells, and they require specialized internal organelles to carry out processes like provide energy, metabolism and transport necessary chemicals throughout the cell.
The level of protein X in these patients will be low due to degradation in the proteasome. Ubiquitnation process occur when ubiquitin is attached to a particular protein and the protein become deactivated. Ubiquitin is a small biochemical molecule which marks out proteins for destruction. Any protein that have ubiquitin attached to it will be transported to the proteasome for destruction by degradation.
Answer:
The activity of cyclic AMP phosphodiesterase is prevented by caffeine. The caffeine prevents further dissociation of cAMP, which eventually increases the response within the body. The activity of neurotransmitters, that is, of noradrenaline or epinephrine, gets increased due to enhancement in response.
This further enhances the activity of the heart, the rate of muscle contractions, blood pressure that further helps in delivering more oxygen to the brain, and other parts of the body. Thus, the inhibition of the enzyme cyclic AMP phosphodiesterase helps the athletes to prevent the wall.
