Chemical reaction is the process by which one or more substances are converted into different substance or substances.
The substances which undergo chemical reaction are called as reactants while the substances which are produced by the reaction are called as products. During chemical reaction, chemical bonds of substrates undergo breaking and formation process to form an entire new product which may have same or different physical and chemical properties as compared to substrates.
Energy is either used or released during the chemical reaction. When the energy is used, it is termed as endothermic reaction but when the energy is produced by the reaction, it is termed as exothermic reaction.
Lastly, gases may or may not participate in a chemical reaction.

Taking into account diabetes, the excess glucose produced in the body, glycosylates the LDL particle, which also obstructs the passage of blood flow through the vessels.
The answer is; the skeletal system and the nervous system
The skeletal system (muscle and bone) give you rigidity and enable your legs to support your weight. The muscles also act on the bone as a fulcrum allowing it possible for them to contract and make motion possible.
The nervous system is important in the coordination of movement. The brain is the center for locomotor action. This ensures you are able to place one foot in front of the other in sequence and moving your arm in concert.
