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.
Water Cycle is the answer
<h2>Mesophyll cells</h2>
Explanation:
The most distinctive characteristic of leaf mesophyll cells is that they are filled with many chloroplasts
Mesophyll cells constitute the main body of a leaf, occurring between upper and lower epidermis
Typically, the leaves of temperate-zone plants have two layers of mesophyll cells, the palisade mesophyll on the upper side and the spongy mesophyll on the lower side
The palisade mesophyll is a layer of densely packed, columnar cells which contain many chloroplasts, this layer is responsible for most of the photosynthesis of leaves
The spongy mesophyll is composed of large, often odd-shaped, photosynthetic cells separated from one another by large, intercellular spaces, these intercellular spaces apparently facilitate the exchange of photosynthetic gases
Traits are located on "Chromosomes" in the nucleus
