It wouldn't be protein synthesis.
Ribosomes produce proteins. In a zoo, ribosomes would most likely be a food vendor.
Protein synthesis would immediately cease.
the synthesis of enzymes would stop
It would get destroyed.
This would depend on the wording of the card's lore. If the card states that "...when this card is sent to the Graveyard..." or "...if this card is destroyed by a card effect...", then it would imply that the effects are activated when it hits the Graveyard. However, if the card states "...when this card is destroyed by battle...", then this would imply that the effect would only activate if it attacked or was attacked and destroyed during the Damage Step. As for Flip Effect Monsters, their effects would only apply if they were flipped face-up before they were destroyed. If not, then their effects are not activated.
The largest number of bound ribosomes would likely be found in cells that are actively synthesizing proteins, such as cells that secrete a large amount of proteins or hormones. These cells would have a high demand for protein production, which requires a significant number of ribosomes attached to the endoplasmic reticulum for protein synthesis.
A pancreatic cell is highly active in protein synthesis, so it would likely have a large number of ribosomes compared to other cell types. Ribosomes are present in both the cytoplasm and attached to the endoplasmic reticulum in a cell.
If the ribosome of a cell were destroyed, it would likely inhibit the cell's ability to synthesize proteins, including those necessary for building and maintaining the cell wall. Without these proteins, the structural integrity and functionality of the cell wall could be compromised, leading to potential cell lysis or instability. Consequently, the overall health and survival of the cell would be significantly affected.
it would be eroded by water and wind. What? it's true!
Protein synthesis will be the cellular activity affected first if ribosomes are destroyed by a toxin. Ribosomes are responsible for translating mRNA into proteins, so their destruction would impair the cell's ability to produce essential proteins for various cellular functions.
If all the mitochondria of a cell were somehow destroyed the cell would most likely die from lack of energy/fuel to carry out its activities.
Not likely, but it would be easier to find a monster that cannot be destroyed by battle.
