the slower pace this imbalance happens it helps the kidneys maintain normal blood PH

Hydrophilic

dissolves easily in water

hydrophobic

does not dissolves easily in water

What is the importance of water in biochem ?

allows anything inside the cell to have the right shape at the molecular level

Simple diffusion ?

movement of molecules from an area in high concentration to low concentration

Osmosis

movement of water through a semipermeable membrane that does not allow solutes to cross

fluid tonicity

solutions in which the solutes is lower concentrated than the cell is hypotonic. solutes more concentrated than cell is called hypertonic

hemostasis

the body needs to reach and maintain a certain state equiliprum

Nucleasomes

section of DNA wrapped around core of protien

histones

group pf protien found in chromatin

chromatin

general term of histones and DNA

Rough ER

Produce protien and ribosomes attached to it

Smooth ER

produce lipids and detoxify toxins through the liver and kidney

What are functions of mitochonderia in animals ?

gives energy depends how much this organelle needs
