Most of the amino acids found free in the cytoplasm come from diet.
Various amino acids are present in the pool of the cytoplasm which include both essential and non-essential amino acids. Essential amino acids are those that cannot be made by the body and must be obtained from food. Non-essential amino acids are those which the body can make on its own.
In the cytoplasm, the essential amino acids found in highest concentration are lysine, threonine, valine and leucine while of the non-essential, glutamine, glycine and alanine are found in higher concentration.

Answer:
Mesopelagic zone
Explanation:
The Mesopelagic zone, also referred to as the Twilight zone, is the second oceanic zone from the top, lying just bellow the Epipelagic zone. It is occupying the waters at depths between 200 meters and 1,000 meters. The sunlight is only managing to reach the top few meters of this zone, while the rest is not receiving any sunlight, thus this zone is not supporting the plant species because they need sunlight for the process of photosynthesis. There are lot of animal species that live in this zone though, and they are ll very well adapted for it, often having hard shells or heavily scaled bodies, larger lungs and heart, and very well developed gills. Some of the animals that live in here are the crabs and the clams. They have developed all the needed characteristics to live in this zone. Because they are prey to lot of larger animals, both the crabs and the clams have started to use the soft sediments at the bottom as cover, digging themselves below it, and mostly managing to evade trouble and end up as food for the other species.
Our ancestors only eat what they needed. They did not splurge, or take their girl friends out on dinner dates for fries and greasy meals. They hunted and they dined in the driest and roughest of places. The CroMagnons, as beautful and naked as they were, because a symbol of humanity towards the future.
