The decomposition of the organisms and the wastes in the soil serves the purpose of nutrient release and space recycling.
The nutrient consumed by an organism as eliminated from his body during his life, and decomposes after he dies. The decomposition releases the nutrients from the dead body, and free up the space that was prior consumed by this organism.
Caffeine since it's an ingredient that boosts you're body in energy.
Celluar respiration breaks down glucose and photosynthesis makes glucose.
When something needs to be transported against its concentration gradient, or a molecule is too big to simply diffuse through a membrane, active transport has to be used. So active transport requires energy (ATP).
Examples:
1. Antiport pumps: transport one substance in one direction while transporting another substance the other way. An example of this is the sodium-potassium pump.
2. Symport pumps - uses a substance that wants to move from an area of high concentration to low concentration and carries another substance against its concentration gradient. An example of this is the sodium-glucose transport protein
3. Endocytosis - large amounts of extra cellular fluid can be taken into a cell - needs ATP to bind proteins in the cell membrane and causes them to change their shape...which eventually causes the surrounding of the fluid to be brought in (a vesicle).
4.exocytosis - opposite of above
