What is the difference between chemical reaction and mechanical reaction?

Answer 1

chemical includes constructing and breaking down large complex molecules sucj as proteins and nucleic acids.

transport involves movement and concentration of raw materials or nutrients for buildng complex molecules or growth of cellular structures.

Mechanical involves movements such as muscle contractions. without a constant source of energy, living systems would not survive

Answer 2

A chemical reaction involves the breaking and forming of chemical bonds resulting in the transformation of substances into new substances with different properties. A mechanical reaction involves forces or movements causing a change in the physical state or shape of a material without altering its chemical composition.

Answer 3

chemical reaction is in your mouth and mechanical reaction is in your stomach
