Answer:
Osmosis
Explanation:
Passive transport does not require energy for movement in and out of a place or across a membrane e.g a cell.
Osmosis uses passive transport to move materials in and out of a cell by setting up concentration gradient through a distance.
Osmosis can be defined as the movement of molecules or particles of a solution from an area of higher concentration to that of lower concentration through a semi-permeable membrane e.g plasma membrane. As we can see, the difference in concentration is the drive for the transport between the two medium. When the concentration is the same, there won't be any movement again.
Answer: Phosphorylation reactions involve the addition of a phosphate group to another molecule called ADP (adenosine diphosphate)
Explanation:
Phosphorylation can of two kinds:
I) Substrate-level Phosphorylation which occurs when ATP is produced from the phosphorylation of ADP coupled to the loss of hydrogen atoms from an organic substrate
II) Oxidative Phosphorylation occurs when ATP is produced from the phosphorylation of ADP by using proton pump fuelled by the electron transport system.
Note that the difference between both (I and II) is that the former occurs independent of the electron transport system, UNLIKE the latter.
Insects become resistant to pesticides after being exposed to it for some time.
