I'm on the highway to hell

Omg, I am so fucking screwed. Somebody kill me now, please, just fucking do it. Oh my god, I am so damn fucking screwed for the fucking bio exam. Oh my god. Help me.
Oh my god. Taking a leaf out of husref's book.
Ribosomes are used in the synthesis of proteins and amino acids.
RER is used to transport proteins around the cells.
SER is used to synthesise lipids and fats, as well, as the detox. of harmful substances.
The cytoplasm is the medium by which all organelles exist. It is mostly made up of water. I think
Cell membrane is a partially permeable membrane that only allows certain organisms in and out of the cell.
The mitochondria is a rod-shaped organelle. It is the site of respiration. It has two membranes, its inner membrane is folded to increase SA for efficient R(x).
The golgi body is used to convert raw proteins from the RER into more complex proteins that are bundled up, and have vesicles pinch them off the golgi body, to be sent to the membrane.
Vacuoles are membrane-bound sacs that hold minerals that are transported around the cell. It is 90% water.
Diffusion is the process whereby molecules move from an area of high concentration to an area of low concentration.
Osmosis is the movement of water down a concentration gradient thru a partially permeable membrane.
Active transport is the movement of molecules against a water gradient, waith energy.
Benedicts test is used to test for reducing sugars. Place an equal vol. of benedicts solution to a volume sample. place it in a boiling bath, the colution should turn brick-red.
Biuret's test is used to test for proteins. Add half to the vol. of food sample NaOH. SHake. Hard. Then add CuSO4 dropwise. the sol. should turn violet.
EMulsion test. Add acohol to a dry test tube containing sample. Wait for clear mixture to appear. Then add water. Elmusion should take place.
Just kill me.
