OKay sure ummm lysosomes obviously have high enzyme activity because they are just vesicles packed with hydrolytic enzymes 2. mitichondria is semi-autonomous organelle that has ribosomeS so obviously enzymes are proteins right so the more the ribosomes the more the hydrolytic activity 3. nuclei manufacture ribosomes (nucleolus) but as you can see they get out of the nucleus so is there isn't much so low activity 4. a single ribosome won't do much damage ;)

this is the trend for hydrolytic enzyme activity, can someone please explain the reason for this trend?View attachment 12914

Lysosomes have the highest hydrolytic activity because their function is to break down (hydrolize) wastes or any unwanted material. Mitochondria hydrolyzes glucose during respiration, but this is nowhere near the amount of hydrolysis in lysosomes. The nucleus does have a little bit of hydrolyzing enzymes (helicase) during DNA replication (DNA needs to be broken down), but this is very little as a cell cycle could take a very long time. Finally, ribosomes barely have any hydrolytic enzymes at all.

so that means tissue fluid doesnt have proteins and platelets, while lymph does
and lymph has more phagocytes than tf

sorry i mislead you in this apparently yeah they do have proteins but im not sure about which fluid has more BUT i can tell you this more phagocytes in lymph and no platelets in either fluid
