I need to know this for a test, please help.
Your metabolism never stops working, it just slows down. Usually later towards the evening, but if you are active (exercising) you can maintain your metabolism at a higher level for longer periods of time.
Usually 7-10. Time depends on your weight and height, also your metabolism will help flush it out of your system but you need to be active, the more active you are the higher your metabolism will be to hurry things along. Alot of water and fluids helps as well.
No. You need to make the word "children" into possessive:"Children's metabolism is known to be higher than adults'.""Children's metabolism is known to be higher than adults' metabolism.""Children's metabolism is known to be higher than that of adults."
Active transport mechanisms occur when particles move from a region of lower concentration to one of higher concentration. This requires energy, which comes from cellular metabolism and, specifically, from a molecule called adenosinetriphosphate(ATP).
Generally a child will have a higher metabolic rate due to the fact that they are more physically active than adults. Also because their metabolic system has not fully matured or developed and can easily be shaped..
men have higher metabolism.
Metabolism is not something you can just "raise" it can take years and years for your metabolism to change.
The cause of a higher metabolism (for example hyperthyroidism) may also make you feel anxious. See a doctor.
I am assuming you mean Ectotherm? Ectotherms are animals that rely on the environmental temperature for their metabolism VS Endotherms that produce their own body heat. Ectotherms become more active in warmer temperatures and sluggish in cooler ones. The exact temperature that affects metabolism is different for different species, so this answer is in general terms. Yes, Ectotherms become more active at higher temperatures. But like Endotherms can be killed by temperature extremes. Some examples of Ectotherms would be most fishes, reptiles, arachnids and the like.
To keep up with their high metabolism.
cortisol
Active transport processes, such as the sodium-potassium pump, require cells to expend energy in the form of ATP. The energy from ATP is needed to move molecules or ions against their concentration gradient, from an area of lower concentration to an area of higher concentration.
