I think its either proteins or enzymes
lipids
enzymes helps control chemical reactions by the chemical in it called collagen when enzymes enter your body they create a chemical reactions and controls the chemical reactions you get by eating too much acids.
Thyroxine controls the rate of chemical reactions or metabolism in the body
In the human body enzymes control the rates of chemical reactions. Enzymes speed up reactions by lowering the activation energy, or the amount of energy required for the reaction to occur.
In the cytoplasm, because that is where the chemical reactions happen.
Compounds that help chemical reactions are called catalysts.
thyroxin
In the cytoplasm, because that is where the chemical reactions happen.
1- defends the body from disease 2- controls the chemical reactions 3- stores nutrients and acts as a chemical messanger
mitochondria
Chemical reactions in the body take place in water.
